The determination of whether a transaction is clearly erroneous under FINRA Rule 11890 is based on a comparison between the transaction price and a reference price, which is typically the consolidated last sale immediately prior to the trade in question. The rule establishes specific numerical guidelines based on the security’s price. For a Tier 1 NMS stock priced at or above $0.00 up to and including $25.00, the threshold for a transaction to be presumed clearly erroneous is a deviation of 10% or more from the reference price. In this scenario, the reference price is $23.50. The execution price is $20.21. The percentage deviation is calculated as follows: \[ \text{Percentage Deviation} = \frac{|\text{Reference Price} – \text{Execution Price}|}{\text{Reference Price}} \] \[ \text{Percentage Deviation} = \frac{|23.50 – 20.21|}{23.50} \] \[ \text{Percentage Deviation} = \frac{3.29}{23.50} \approx 0.14 \] This represents a 14% deviation from the reference price. Since the 14% deviation is greater than the 10% threshold applicable to stocks in this price range, the transaction is presumed to be clearly erroneous. This presumption allows the executing firm to submit a review request to FINRA. The rule’s purpose is to provide a mechanism to rectify trades that occur at prices so far from the prevailing market that their execution would be detrimental to the integrity of the market. The determination is based on the objective numerical guideline, not on the order type or the size of the transaction, although other factors can be considered by FINRA in its review.

First, the Reference Price is established as the consolidated last sale immediately prior to the transaction in question, which is $55.00. Next, the applicable Numerical Guideline from FINRA Rule 11890 for an NMS stock priced above $50.00 during regular trading hours (9:30 a.m. – 4:00 p.m. ET) is determined. This guideline is 10%. Then, the price threshold is calculated. Since this was a sell order, the lower boundary of the acceptable price range is calculated. Lower Boundary = Reference Price × (1 – Numerical Guideline) Lower Boundary = \( \$55.00 \times (1 – 0.10) = \$55.00 \times 0.90 = \$49.50 \) The execution price of $48.95 is compared to this lower boundary. Since $48.95 is less than $49.50, the transaction’s price deviates from the Reference Price by an amount that exceeds the Numerical Guideline. Therefore, the transaction is found to be clearly erroneous. Finally, the resolution is determined. Under FINRA Rule 11890, for a standard clearly erroneous transaction in an NMS stock that is not an Outlier Transaction (i.e., a deviation of 3 times the Numerical Guideline or more), the transaction is adjusted to the price that is least disruptive to the market. This price is the Reference Price itself. Therefore, the trade will be adjusted to $55.00. FINRA Rule 11890 provides a framework for addressing transactions that occur at prices so far from the prevailing market that they are clearly a result of error. The process begins by identifying the Reference Price, which is typically the last consolidated sale price before the disputed trade. Based on this price and the time of day, a specific percentage-based Numerical Guideline is applied. For NMS stocks trading above $50.00 during regular market hours, this guideline is 10%. A transaction is deemed clearly erroneous if its price deviates from the Reference Price by an amount equal to or greater than this guideline. Once a trade is found to be clearly erroneous, a FINRA Officer determines the remedy. The standard procedure, unless both parties agree otherwise or it qualifies as an Outlier Transaction, is to adjust the trade price to the original Reference Price. This approach is considered the least disruptive to the market, as it effectively reprices the execution to the last valid market price before the error occurred, rather than nullifying the trade entirely or adjusting it to the edge of the guideline threshold. This process ensures fairness and maintains market integrity by correcting obvious errors without completely voiding the transaction.

The determination of whether a transaction is clearly erroneous under FINRA Rule 11890 is based on numerical guidelines that compare the transaction price to a reference price. The reference price is typically the consolidated last sale immediately preceding the transaction in question. In this scenario, the reference price for INVD stock is $50.00. For an NMS stock with a reference price between $25.00 and $50.00 inclusive, the numerical guideline for a clearly erroneous transaction is a deviation of 10%. The first step is to calculate the threshold price deviation in dollars. This is done by multiplying the reference price by the guideline percentage: \[\$50.00 \times 10\% = \$5.00\] This means any trade occurring more than $5.00 away from the reference price of $50.00 may be considered clearly erroneous. The next step is to calculate the actual deviation of the trade in question. The trade executed at $44.00. The deviation from the reference price is: \[|\$50.00 – \$44.00| = \$6.00\] The final step is to compare the actual deviation to the calculated threshold. The actual deviation of $6.00 is greater than the $5.00 threshold. Because the transaction price deviates from the reference price by an amount that exceeds the applicable numerical guideline, an exchange official will rule the transaction to be clearly erroneous. The standard procedure for such a ruling, when the trade is not within the “Outer Boundary” for adjustment, is to nullify the trade, effectively voiding it as if it never happened.

Step 1: Identify the firm’s primary regulatory constraint. Apex Trading is a distribution participant in a secondary offering for INVC, making it subject to SEC Regulation M, Rule 101. This rule generally prohibits the firm from bidding for or purchasing a covered security during the restricted period. Step 2: Identify the nature of the customer’s order and the associated obligations. The order from Provident Trust is for \(500,000\) shares, which qualifies as a block transaction. This brings FINRA Rule 5270 (Front Running of Block Transactions) into consideration. The firm has a duty of best execution to its customer. Step 3: Analyze the exceptions within the applicable regulations. Regulation M, Rule 101(b)(5) provides a specific exception for unsolicited brokerage transactions. Since the order from Provident Trust was not solicited by Apex Trading, the firm is permitted to accept and execute it on an agency basis. Step 4: Synthesize the requirements. The firm is caught between its role as a distribution participant and its duty to a brokerage client. The exception for unsolicited brokerage transactions in Regulation M is critical. It allows the firm to fulfill its duty to the customer without violating its obligations as an underwriter. However, the firm must be extremely careful not to use the knowledge of this large incoming order for its own benefit, such as by adjusting its proprietary positions or influencing the offering price. The most appropriate course of action involves executing the customer’s order while ensuring that information barriers (i.e., Chinese Walls) are maintained between the trading desk handling the customer order and the syndicate/underwriting department involved in the distribution. This prevents the material, non-public information about the block order from improperly influencing activities related to the offering, thereby satisfying the principles of both Regulation M and FINRA Rule 5270. The core regulatory challenge is managing the dual roles of distribution participant and broker. Regulation M’s prohibitions are strict, but they are not absolute and contain specific, well-defined exceptions to allow for normal course of business activities, such as handling unsolicited customer orders. The exception under Rule 101(b)(5) is designed for precisely this type of scenario. It allows a firm to continue servicing its clients without having to cease its entire brokerage operation in a security it is underwriting. The key is the unsolicited nature of the transaction. If the firm had solicited the order, the exception would not apply. Furthermore, the firm must ensure that its actions do not constitute front-running. Executing the customer order is permissible, but trading ahead of it for the firm’s own account or using the information to benefit the distribution would be a clear violation. Therefore, robust information barriers are a necessary compliance control to manage this conflict of interest and demonstrate that the customer order was handled appropriately and without misuse of information.

The reference price for determining if a transaction is clearly erroneous is the consolidated last sale price immediately preceding the transaction(s) in question. In this scenario, the reference price is \( \$49.95 \). According to FINRA Rule 11890, for an NMS stock with a reference price above \( \$25.00 \) and up to and including \( \$50.00 \), the numerical guideline for a clearly erroneous transaction is a price deviation of \( 10\% \). To determine the threshold price, we calculate \( 10\% \) of the reference price: \[ \$49.95 \times 0.10 = \$4.995 \] The price at which a transaction would be considered clearly erroneous is any price at or below the reference price minus this deviation: \[ \$49.95 – \$4.995 = \$44.955 \] The lowest execution price was \( \$35.00 \), which is significantly below the \( \$44.955 \) threshold. The actual deviation percentage for the lowest trade is: \[ \frac{(\$49.95 – \$35.00)}{\$49.95} \approx 29.9\% \] Since \( 29.9\% \) is greater than the \( 10\% \) guideline, the transactions qualify for review as clearly erroneous. Regarding the procedure, FINRA Rule 11890 specifies the timing for submitting a review request. For transactions occurring at or after 3:55 PM Eastern Time, the request must be submitted by 9:30 AM Eastern Time on the next trading day. Because the event occurred at 3:55 PM ET, this extended deadline applies. Upon review, a FINRA officer or the relevant exchange has the authority to declare the transactions null and void (break the trades) or adjust the execution price. Given the severity of the price dislocation across multiple executions, nullifying the trades that occurred at or below the threshold is a highly probable outcome.

The determination of a violation is based on the specific constraints of SEC Regulation M, Rule 103, which governs passive market making. 1. Identify the governing regulation: A broker-dealer acting as a distribution participant and also making a market in the same security must comply with Regulation M. The firm has elected to operate under the Rule 103 safe harbor for passive market making. 2. Analyze the core principle of Rule 103: A passive market maker is prohibited from entering a bid or effecting a purchase at a price that exceeds the highest current independent bid for the security. The purpose of this rule is to prevent the market maker from artificially supporting or raising the price of the security it is distributing. 3. Evaluate the action in question: The firm enters a bid at $50.26. The highest independent bid (the NBB from other market participants not involved in the distribution) is $50.25. 4. Conclusion: By entering a bid of $50.26, the firm’s bid exceeds the highest independent bid of $50.25. This action would create a new, higher national best bid, which is explicitly forbidden for a passive market maker. Therefore, this action constitutes a violation of Rule 103. SEC Regulation M provides exceptions to the general prohibitions against bidding for or purchasing securities during a distribution. Rule 103 specifically allows a broker-dealer to engage in passive market making for a Nasdaq security, provided it adheres to strict limitations. The fundamental restriction is that a passive market maker’s bid cannot at any time exceed the highest bid placed by an independent market maker. This prevents the distribution participant from leading the market upward or creating artificial price support. Furthermore, a passive market maker’s daily net purchases are limited to the greater of 30% of its average daily trading volume (ADTV) in that security or 200 shares. If the highest independent bid drops, the passive market maker must lower its bid accordingly, although it is not required to do so immediately. However, under no circumstances can it enter a bid that would establish a new high for the market. The rule is designed to permit liquidity provision without allowing for manipulative activity that could improperly influence the offering’s success.

The correct course of action is for Kenji to continue his normal trading activity based on his independent analysis of publicly available market data. FINRA Rule 5270, the front running rule, prohibits a member from trading a security or a related financial instrument when the member has material, non-public market information concerning an imminent block transaction in that security. A block is generally defined as a transaction of at least 10,000 shares or a market value of at least $200,000. The critical element is the possession of material, non-public information about the block order itself, such as its size, side, or limit price. The rule provides specific exceptions. One of the most important is for firms that have established and maintain effective information barriers, or Chinese Walls, between the department with the block order information (e.g., the institutional desk) and other departments that trade for the firm’s account (e.g., the proprietary trading desk). If these procedures are in place and effective, and the proprietary trader has no actual knowledge of the customer’s block order, trading by the proprietary desk is not considered a violation. In this scenario, Kenji’s observations are based entirely on market data that is available to all participants. He is observing unusual volume and price action, which is a form of market intelligence, not a breach of non-public information from his firm’s institutional desk. His firm’s information barrier is specifically designed to prevent the non-public details of the block order from reaching him. Therefore, his trading decisions, derived from his own analysis of public data, do not constitute front running.

The determination of the correct action rests on the specific exceptions outlined in FINRA Rule 5280 regarding trading ahead of research reports. The primary purpose of this rule is to prevent a member firm from using its advance knowledge of its own research to trade for its own benefit in its principal account. However, the rule is not intended to paralyze legitimate, client-driven business when proper controls are in place. The rule contains critical exceptions for information barriers and the facilitation of unsolicited customer orders. In this scenario, the firm has established and documented information barriers, or firewalls, between the research department and the trading desk. This means the trading desk is not privy to the content or timing of the upcoming research report. Furthermore, the order from the institutional client is explicitly unsolicited. Therefore, the trading desk is not acting on the basis of the nonpublic research information. Fulfilling a duty to a client by executing an unsolicited order is a permissible activity. This can include the firm acting in a principal capacity to facilitate the large block trade for the client, provided this action is consistent with the firm’s normal market making or facilitation activities and is not a pretext to circumvent the rule’s core prohibition. The combination of an effective information barrier and the unsolicited nature of the client’s order makes the execution permissible under the rule.

The core issue revolves around the specific constraints placed on a passive market maker under SEC Regulation M, Rule 103. This rule provides a safe harbor for a distribution participant to continue making a market in a security during a distribution’s restricted period, but only under strict conditions designed to prevent manipulation. The most critical of these conditions is that a passive market maker’s bid cannot exceed the current highest independent bid (HIB) for the security. An independent bid is one made by a market maker who is not a participant in the distribution. In this scenario, the highest independent bid is $25.50. The customer has submitted a limit order to buy at $25.52. Displaying this order would require the firm to post a bid of $25.52. Since $25.52 is higher than the HIB of $25.50, the firm is explicitly prohibited from displaying this bid while acting as a passive market maker. The firm’s obligation to display a customer limit order under Regulation NMS does not override the specific prohibitions of Regulation M during a distribution. To handle the order, the trader must either route the order to another market center for execution or display, or the firm must withdraw its registration as a passive market maker for that security before it can display a bid at $25.52.

The proposed action constitutes a violation of FINRA Rule 5270. The core of the issue is front running, which is the prohibited practice of trading a security or a related financial instrument while in possession of material, nonpublic information concerning an imminent block transaction in that security. First, the 500,000 share order for Global Tech Inc. (GTI) clearly qualifies as a block transaction, which is generally defined as a transaction involving at least 10,000 shares or a quantity of stock with a market value of $200,000 or more, whichever is less. The knowledge of this impending large order is considered material, nonpublic market information because it is reasonable to expect its execution will impact the market price of GTI. Second, FINRA Rule 5270 explicitly extends the prohibition beyond the security itself to any “related financial instrument.” This includes options, derivatives, or any security convertible into the underlying security. Therefore, trading GTI call options based on the knowledge of the impending stock block order falls directly under the rule’s purview. Third, the violation is triggered by the possession of the information and the subsequent trading activity, not by the formal transmission of the block order to an execution venue. The fact that the institutional desk is still finalizing terms does not negate the fact that the trader has knowledge of an “imminent” block transaction. The firm has the information, and any proprietary trading based on that information before it is made public is a breach of the rule. The intent is to prevent the firm or its employees from profiting from advance knowledge of a client’s large order that can move the market.

Kenji’s actions constitute a violation of FINRA Rule 5270. The purchase of the call options based on the knowledge of the imminent block trade is a prohibited activity known as front running. FINRA Rule 5270, the front running rule, prohibits a member from trading a security or a related financial instrument for its own account, or for an account over which it has discretion, when it possesses material, non-public market information concerning an imminent block transaction in that security. A block transaction is generally defined as an order for 10,000 shares or more, or a quantity of stock with a market value of $200,000 or more. The information Kenji received about the 250,000 share buy order for XYZ Corp. clearly qualifies as material, non-public information about an imminent block transaction. The rule explicitly includes trading in related financial instruments, which encompasses options, futures, and other derivatives. By purchasing XYZ call options just before the block trade was expected to execute, Kenji was attempting to profit from the anticipated upward price movement that the large buy order would likely cause. This action is a direct violation of the rule’s intent, which is to prevent market participants from taking unfair advantage of information that is not available to the public. The rule’s permitted exceptions, such as for bona fide market making or hedging a pre-existing position, do not apply to Kenji’s speculative transaction.

The daily purchase limit for a passive market maker under SEC Regulation M, Rule 103 is the greater of 30% of its average daily trading volume (ADTV) or 200 shares. First, calculate the firm’s daily purchase limit based on its ADTV. ADTV = 100,000 shares Purchase Limit = \(0.30 \times 100,000 \text{ shares} = 30,000 \text{ shares}\) Since 30,000 is greater than 200, the daily purchase limit is 30,000 shares. Next, calculate the firm’s net purchases for the day. The limit applies to net purchases, not gross purchases. Gross Purchases = 35,000 shares Sales = 4,000 shares Net Purchases = \(35,000 \text{ shares} – 4,000 \text{ shares} = 31,000 \text{ shares}\) Finally, compare the net purchases to the daily purchase limit. Net Purchases (31,000) > Purchase Limit (30,000) The firm’s net purchases exceeded its permissible daily limit. SEC Regulation M is designed to prevent manipulation by individuals with an interest in the outcome of an offering. Rule 103 specifically provides an exception for market makers who are also distribution participants, allowing them to engage in passive market making for a Nasdaq security that is the subject of an offering. This activity is strictly regulated to ensure the market maker does not artificially influence the stock’s price. A passive market maker’s bids and purchases are subject to two primary limitations. First, its bid cannot exceed the highest current independent bid for the security. Second, its daily net purchases are restricted. The limit is calculated as the greater of 30 percent of the market maker’s average daily trading volume (ADTV) in the security or 200 shares. It is critical to understand that this is a net purchase limit, meaning the market maker’s total purchases minus its total sales for the day cannot exceed this threshold. In this scenario, the firm’s net buying activity surpassed its calculated 30 percent ADTV limit, constituting a direct violation of the rule’s volume constraint. This rule ensures that while a distribution participant can provide liquidity, it cannot become an overly aggressive buyer that could improperly support the security’s price during the distribution period.

The trader’s action constitutes a violation of FINRA Rule 5270, which governs the front running of block transactions. This rule prohibits a member or an associated person from trading for their own account, or soliciting others to trade, when they possess material, non-public market information concerning an imminent block transaction in that security, a related financial instrument, or a security underlying the related financial instrument. In this scenario, the information about the 500,000-share buy order is clearly material, as it is reasonably certain to affect the market price of the stock. It is also non-public, as it has not been widely disseminated. The fact that the trader overheard this information rather than receiving it through a formal channel does not change its non-public nature. Crucially, FINRA Rule 5270’s prohibition extends beyond the security itself to include related financial instruments. Options are explicitly defined as related financial instruments. Therefore, by purchasing call options on the stock with the knowledge of the impending block purchase, the trader is engaging in a prohibited activity. The intent is to profit from the anticipated price movement caused by the block order. The rule is not limited to only the firm handling the block order; it applies to any member or associated person who comes into possession of such knowledge. The trader’s actions are a direct attempt to capitalize on advance information about a market-moving event, which is the precise conduct the front-running rule is designed to prevent.

The determination of a clearly erroneous transaction under FINRA Rule 11890 is based on specific numerical guidelines relative to a reference price. The reference price is the consolidated last sale price immediately prior to the transaction in question, which is \( \$48.50 \). For an NMS stock priced between \( \$25.00 \) and \( \$50.00 \), the numerical guideline for a transaction to be considered clearly erroneous is a deviation of 10% or more from the reference price. First, calculate the percentage deviation of the trade: Percentage Deviation = \(\frac{|\text{Transaction Price} – \text{Reference Price}|}{\text{Reference Price}}\) Percentage Deviation = \(\frac{|\$52.00 – \$48.50|}{\$48.50}\) Percentage Deviation = \(\frac{\$3.50}{\$48.50} \approx 0.07216\) or \(7.22\%\) Next, compare this deviation to the rule’s threshold: The calculated deviation is \(7.22\%\). The FINRA threshold for this price range is \(10\%\). Since \(7.22\%\) is less than the \(10\%\) threshold, the transaction does not meet the numerical criteria to be deemed clearly erroneous. Therefore, the trade will be upheld. FINRA Rule 11890 establishes objective numerical guidelines to determine if a trade qualifies as clearly erroneous. This process is designed to bring finality to trades and provide a fair mechanism for addressing obvious errors without disrupting the market. For a trade to be considered for nullification or adjustment, a member firm must submit a review request, typically within 30 minutes of the execution. FINRA officials then evaluate the trade against the reference price, which is almost always the last consolidated sale before the disputed trade. The applicable percentage deviation varies based on the security’s price and the time of the trade. In this scenario, the stock’s reference price of \( \$48.50 \) falls into the category where a 10% deviation is required. The actual trade’s deviation was calculated to be approximately \(7.22\%\). Because this figure is below the 10% threshold, the trade does not meet the presumptive requirements for being clearly erroneous. While officials have some discretion, particularly in cases involving multiple disruptive trades or other extraordinary circumstances, a single trade falling this far inside the guideline is overwhelmingly likely to be upheld. The intent of the trader or the cause of the error is not the primary factor; the objective numerical deviation is the key determinant.

The core of this scenario revolves around the specific obligations of a passive market maker under SEC Regulation M, Rule 103. A passive market maker is a market maker that is also a distribution participant in an offering. To prevent manipulation during the restricted period, its market making activities are limited. The primary rule is that a passive market maker’s bid cannot exceed the highest independent bid for the security at the time the bid is entered. In this case, the initial highest independent bid was $25.10, and Apex permissibly entered its bid at that price. When the highest independent bid subsequently drops to $25.05, a key provision of Rule 103 comes into play. The rule does not require the passive market maker to immediately lower its bid. The passive market maker is permitted to maintain its bid at the higher price ($25.10) until that bid is either executed or the firm itself decides to update or withdraw it. This provision allows the passive market maker to provide liquidity without being forced to contribute to downward price pressure, which could be detrimental during an offering. Therefore, the permissible action is to maintain the existing bid. Lowering the bid is an option but not a requirement. Raising the bid is prohibited, and withdrawing the quote is also an option but not the only permissible course of action.

The determination of a violation is based on a step-by-step analysis of the trader’s actions against specific FINRA rules. Step 1: Identify the information obtained by the trader. The trader, Kenji, obtained knowledge of an imminent 200,000-share buy order. This qualifies as a block transaction, which is generally considered to be an order for 10,000 shares or more of a single stock or a quantity of stock with a market value of $200,000 or more. Step 2: Assess the nature of the information. The information about the impending block order was not publicly available. Therefore, it constitutes material, non-public market information. Step 3: Analyze the trader’s action. The trader executed a proprietary trade in the same security (INVT) based on this non-public information before the institutional order was made public or had a chance to be executed. Step 4: Apply the relevant regulation. This action falls directly under the prohibition of FINRA Rule 5270, Front Running of Block Transactions. This rule prohibits a member from trading a security or a related financial instrument for its own account while in possession of material, non-public information concerning an imminent block transaction in that security. Step 5: Evaluate the outcome. The fact that the institutional block order was a limit order that never executed, and that the trader’s position may not have been profitable, is entirely irrelevant to the determination of the violation. The violation occurred at the moment the proprietary trade was executed with the knowledge of the imminent block transaction. The rule is designed to prevent traders from taking advantage of such information, regardless of the final outcome of either the block order or the proprietary trade.

This is a conceptual question and does not require a mathematical calculation. The core issue is the application of FINRA Rule 5320, Prohibition Against Trading Ahead of Customer Orders. FINRA Rule 5320 generally prohibits a member firm from trading a security for its own account when the firm has an unexecuted customer order for that same security that could be executed at the same or a better price. In this scenario, Apex Trading Solutions holds a large institutional customer limit order to buy stock XYZ at or below a specific price. Subsequently, the firm’s proprietary trading algorithm executes buy orders for the firm’s own account in XYZ at prices that would have satisfied the customer’s limit order. The critical factor is that Kai, the proprietary trader, has knowledge of the customer’s order. Even though an algorithm executed the proprietary trades, Kai is responsible for the trading activity of his desk. The rule provides for certain exceptions, such as the establishment of effective information barriers between the department handling the customer order and the proprietary trading department. However, since Kai himself is aware of the customer order, no effective information barrier exists with respect to his proprietary trading activities. His knowledge of the unexecuted customer order, combined with the firm’s proprietary trading at prices that would have fulfilled that order, constitutes a violation. The automated nature of the execution does not absolve the firm or the trader of their responsibility under the rule, as the trader with knowledge of the customer order is ultimately responsible for the proprietary trading system’s actions. The firm has failed to prevent its proprietary interests from being placed ahead of its customer’s interests.

The proprietary trade is permissible under the specific exceptions to FINRA Rule 5320. The general principle of Rule 5320, the prohibition against trading ahead of customer orders, states that a firm holding a customer order may not trade a security for its own account at a price that would satisfy the customer’s order, unless the firm immediately thereafter executes the customer’s order up to the size and at the same or better price than it traded for its own account. However, the rule provides specific exceptions, most notably for orders from institutional accounts. For this exception to apply, several conditions must be met. First, the customer must qualify as an “institutional account” as defined in FINRA Rule 4512(c), which includes entities like banks, insurance companies, registered investment companies, and any person with total assets of at least 50 million dollars. In this scenario, the pension fund with over 1 billion dollars in assets clearly meets this definition. Second, the member firm must have provided clear written disclosure to the institutional customer, both at the time of account opening and annually thereafter, stating that the firm may trade for its own proprietary account at prices that could satisfy the customer’s order. Third, the institutional customer must have been given a clear opportunity to “opt-in” to the full protections of Rule 5320, and in this case, the customer affirmatively chose not to. Since all these conditions were met—the client is an institutional account, proper disclosures were made, and the client did not opt-in to the rule’s protections—the firm’s proprietary trading desk is permitted to execute its own order without being in violation of the trading ahead rule.

The determination of whether a trade is clearly erroneous is governed by FINRA Rule 11890, which sets specific numerical guidelines based on the security’s price. The first step is to establish the reference price, which is the consolidated last sale price immediately preceding the transaction in question. In this scenario, the reference price is \(\$65.00\). Next, the appropriate percentage guideline must be identified. For NMS stocks priced above \(\$50.00\), the guideline for a transaction to be presumptively erroneous is a deviation of \(10\%\) or more from the reference price. The threshold price is then calculated by applying this percentage to the reference price. The deviation amount is \(\$65.00 \times 10\% = \$6.50\). For a sell order that drives the price down, the erroneous price threshold is the reference price minus the deviation amount: \(\$65.00 – \$6.50 = \$58.50\). The trade in question executed at \(\$57.85\). Since this price is below the calculated threshold of \(\$58.50\), the transaction is deemed clearly erroneous. When a trade is found to be clearly erroneous but does not meet the more extreme criteria for nullification (typically a \(20\%\) deviation for this price range), the standard procedure is to adjust the trade price. The transaction is not busted but is repriced to the nearest point of the non-erroneous range, which is the threshold price itself. Therefore, the execution at \(\$57.85\) will be adjusted to \(\$58.50\). This process ensures market integrity by correcting obvious errors without completely voiding the transaction, balancing the interests of both parties involved.

The calculation to determine the adjusted trade price is as follows: 1. Identify the Reference Price: The consolidated last sale immediately prior to the transaction in question is \( \$23.50 \). 2. Determine the Applicable Numerical Guideline: According to FINRA Rule 11890, for NMS stocks with a Reference Price at or above \( \$0.00 \) and up to and including \( \$25.00 \), the numerical guideline for a clearly erroneous transaction is 10%. 3. Calculate the Percentage Deviation of the Trade: \[ \text{Deviation} = \frac{|\text{Reference Price} – \text{Trade Price}|}{\text{Reference Price}} \] \[ \text{Deviation} = \frac{|\$23.50 – \$20.50|}{\$23.50} = \frac{\$3.00}{\$23.50} \approx 0.1277 \text{ or } 12.77\% \] Since 12.77% is greater than the 10% guideline, the transaction is presumptively clearly erroneous. 4. Calculate the Adjusted Price: When a trade is adjusted, it is priced at the Reference Price, plus or minus the numerical guideline percentage. Since the erroneous trade was executed below the Reference Price, the adjustment is made by subtracting the guideline amount from the Reference Price. \[ \text{Guideline Amount} = \text{Reference Price} \times \text{Numerical Guideline} \] \[ \text{Guideline Amount} = \$23.50 \times 0.10 = \$2.35 \] \[ \text{Adjusted Price} = \text{Reference Price} – \text{Guideline Amount} \] \[ \text{Adjusted Price} = \$23.50 – \$2.35 = \$21.15 \] FINRA Rule 11890 provides a framework for addressing transactions that are clearly erroneous. The rule establishes specific numerical guidelines to determine if a trade’s price deviates substantially from the prevailing market. For NMS stocks, these guidelines are tiered based on the transaction’s reference price, which is typically the consolidated last sale price immediately preceding the trade. In this scenario, the stock’s reference price of twenty three dollars and fifty cents falls into the tier for securities priced up to and including twenty five dollars, which has a ten percent deviation threshold. The executed trade’s price represents a deviation greater than this ten percent threshold, making it presumptively erroneous. When FINRA or an exchange determines that a trade is clearly erroneous and decides to adjust it rather than bust it, the price is not simply reset to the reference price. Instead, the trade is repriced to the reference price plus or minus the permitted deviation amount. Because the erroneous trade occurred below the reference price, the new, adjusted price is calculated by taking the reference price and subtracting the value of the ten percent guideline. This ensures the adjusted price falls precisely at the outer boundary of what would have been considered a non-erroneous price.

The arrangement described is a violation of FINRA Rule 5250. This rule explicitly prohibits a member firm from accepting any payment or other consideration, directly or indirectly, from an issuer or its affiliates and promoters, for publishing a quotation, acting as a market maker in a security, or submitting an application in connection therewith. The core of the issue lies in the definition of “other consideration.” While no direct cash payment is being made, the promise of exclusive order flow for all of NanoVate’s corporate treasury stock buybacks is a significant, tangible benefit. This benefit is being offered specifically to induce Apex Trading to perform its market-making duties in a particular way, namely by maintaining a continuous and tight two-sided quote. The rule is designed to prevent such conflicts of interest, ensuring that a market maker’s quotations are the result of independent judgment and market conditions, not compensation from the issuer. An issuer paying for liquidity or a tighter spread compromises the integrity of the market and the market maker’s role. Therefore, linking the valuable and exclusive order flow to the performance of market-making functions constitutes a prohibited quid pro quo under Rule 5250.

This is a non-mathematical question. The solution is arrived at through logical deduction based on FINRA rules. Step 1: Identify the relevant regulations. The scenario involves two distinct pieces of material, nonpublic information. The first is the knowledge of an impending institutional block order to buy, which is governed by FINRA Rule 5270, Prohibition Against Front Running of Block Transactions. The second is the knowledge of a pending research report with a “Strong Buy” rating, which is governed by FINRA Rule 5280, Trading Ahead of Research Reports. Step 2: Analyze the impact of FINRA Rule 5270. This rule prohibits a member from trading a security for its own account when it possesses material, nonpublic market information concerning an imminent block transaction in that security. The 500,000 share “not held” order from the institutional client clearly constitutes a block transaction. The trader’s awareness of this order, before it is fully executed and reflected in the market, is material nonpublic information. Therefore, establishing a proprietary long position in the same security would be a direct violation of the front-running rule. Step 3: Analyze the impact of FINRA Rule 5280. This rule prohibits a firm from purposefully altering its inventory position in a security in its principal account based on material, nonpublic information regarding the content or timing of its own research report. The trader is aware that the research department will issue a “Strong Buy” recommendation. This is material information that is not yet public. Establishing a long position in anticipation of the price increase that may follow the report’s dissemination is a clear violation of this rule. Step 4: Synthesize the findings. The trader possesses two independent pieces of information, each of which, on its own, would prohibit the proposed proprietary trade. The existence of one violation does not negate or permit the other; it compounds the prohibited nature of the activity. The firm cannot use one piece of nonpublic information to justify trading on another. Therefore, the proprietary trading desk is unequivocally barred from establishing a long position in the security.

1. Identify the governing rule: The scenario involves trading ahead of a large customer order, which is primarily governed by FINRA Rule 5270, Prohibition Against Trading Ahead of Customer Orders (Front Running). 2. Analyze the elements of a front-running violation under Rule 5270. A violation occurs when a firm or associated person, with material, non-public knowledge of an imminent block transaction, executes an order for a proprietary account or a discretionary account in the same security, a related financial instrument, or an option on the same side of the market to capitalize on the transaction’s market impact. 3. Evaluate the facts of the scenario against these elements. – Imminent Block Transaction: Yes, the firm received a 500,000 share order. – Proprietary Trade: Yes, Anika traded for the firm’s proprietary account. – Related Instrument: Yes, Anika traded call options, which are related financial instruments. – Possession of Material, Non-Public Information: This is the critical element. The scenario explicitly states that Anika was unaware of the institutional block order and that a robust information barrier existed between her proprietary trading desk and the institutional desk. 4. Conclude based on the analysis. Since Anika did not possess the material, non-public information about the block order, a key prerequisite for a front-running violation is missing. The existence of effective information barriers is a recognized method for firms to prevent the misuse of such information between departments. Therefore, her trade, based on independent analysis, does not constitute front-running. FINRA Rule 5270 is designed to prevent individuals and firms from misusing advance knowledge of large, market-moving orders for their own benefit. The rule’s definition of a violation hinges on the possession of material, non-public information concerning the terms and conditions of an imminent block transaction. This includes information about the security, the size of the order, and the side of the market. The prohibition extends beyond the specific security to include any related financial instrument, such as options or convertible securities, whose value would likely be affected by the execution of the block order. A critical component of compliance for multi-service firms is the implementation of effective information barriers, often called Chinese Walls. These are policies and procedures designed to prevent the flow of sensitive information between departments, such as between an institutional sales desk that receives client orders and a proprietary trading desk. If these barriers are properly established and maintained, and a trader in one department acts without the knowledge possessed by another, a violation of Rule 5270 can be avoided, even if the timing of the trades appears advantageous. The trader’s actions must be based on legitimate, independent analysis, and the firm must be able to document the effectiveness of its information barriers.

The determination of whether a transaction is clearly erroneous is governed by FINRA Rule 11890, which establishes numerical guidelines based on the security’s price. The first step is to identify the correct reference price, which is the consolidated last sale price immediately preceding the transaction in question. In this scenario, the reference price is $44.90. Next, the appropriate numerical guideline must be applied. For an NMS stock priced at or above $25.00 but less than or equal to $50.00, the threshold for a clearly erroneous transaction is a deviation of 10% or more from the reference price. The calculation of the percentage deviation is as follows: The absolute price deviation is the difference between the reference price and the trade price: \[ \$44.90 – \$35.10 = \$9.80 \] The percentage deviation is this absolute deviation divided by the reference price: \[ \frac{\$9.80}{\$44.90} \approx 0.21826 \] Expressed as a percentage, this is approximately 21.83%. Since 21.83% is greater than the 10% threshold, the transaction qualifies as clearly erroneous. When a trade is deemed clearly erroneous but does not meet the criteria for nullification, FINRA will typically adjust the execution price. The adjustment is made to the price level that represents the outer limit of the numerical guideline. For a trade executed below the reference price, the adjustment price is calculated by subtracting the guideline percentage from the reference price. The adjustment calculation is: \[ \text{Adjustment Price} = \text{Reference Price} \times (1 – \text{Numerical Guideline}) \] \[ \text{Adjustment Price} = \$44.90 \times (1 – 0.10) \] \[ \text{Adjustment Price} = \$44.90 \times 0.90 \] \[ \text{Adjustment Price} = \$40.41 \] Therefore, the transaction will be repriced to $40.41. This process ensures that the parties to the trade are brought back to a price that would not have been considered clearly erroneous, maintaining market integrity without completely voiding the transaction.

The firm, Apex Trading Solutions, has committed a violation of FINRA Rule 5280. The core of this rule is to prevent a member firm from using advance knowledge of its own research to its advantage in the market, thereby disadvantaging clients and undermining the integrity of the research. The rule specifically prohibits a member firm from purposefully altering its inventory in a security or a related derivative in its proprietary account while in possession of material, non-public information concerning an imminent research report on that security. In this scenario, a research report containing a material change—an upgrade from “Neutral” to “Buy” and a significant price target increase—was being prepared within the firm. The firm’s proprietary trading desk then increased its inventory in the subject security, INVD. The violation is assessed at the firm level. The fact that the individual trader, Marco, was not explicitly told about the report’s contents is not a valid defense for the firm. The firm is considered to be in possession of the information as soon as its research department creates it. The firm has an obligation to establish, maintain, and enforce robust information barriers, or “Chinese Walls,” to prevent information from passing between the research and trading departments and to restrict proprietary trading activity in such circumstances. Marco’s trading, even if based on his own analysis of market data, represents a failure of these controls and constitutes the firm trading ahead of its own research report. The rule’s purpose is to prevent the very appearance of impropriety and to ensure that the firm does not profit from information before it is disseminated to clients who may rely on it.

The core issue is whether the proprietary trading desk’s actions constitute front running under FINRA Rule 5270. Front running is the practice of trading a security based on advance knowledge of a large, non-public customer order that is likely to affect the security’s price. In this scenario, the institutional sales desk’s receipt of the large block order for INVC stock is considered material non-public information. The rule prohibits a member firm from trading the subject security or a related financial instrument for its own account when it possesses this information. However, FINRA Rule 5270 provides specific exceptions. A critical exception applies to firms that have implemented effective information barrier policies and procedures. If a firm can demonstrate that the proprietary trading was conducted by a separate department that did not have actual knowledge of the customer’s block order, and the trading decision was based on independent analysis, it is not a violation. In this case, the proprietary desk’s trading was triggered by a quantitative model reacting to public market data, specifically the price and volume changes resulting from the initial partial executions of the block. The desk was not acting on knowledge of the impending, unexecuted portion of the block order. Therefore, as long as the information barrier between the institutional sales desk and the proprietary trading desk is robust and effective, the proprietary desk’s trades do not constitute a front-running violation. The rule’s intent is to prevent trading based on the confidential knowledge of the order itself, not to prohibit legitimate trading strategies that react to public market information, even if that information is a byproduct of the block order’s execution.

The core of this scenario involves evaluating potential violations of FINRA Rule 5270 (Front Running of Block Transactions) and FINRA Rule 5280 (Trading Ahead of Research Reports) within a multi-service broker-dealer. The proprietary trader’s actions must be assessed in light of the firm’s internal controls, specifically its information barriers. 1. Identify the material, non-public information (MNPI) present within the firm: a. Knowledge of the institutional client’s impending block sale order. b. Knowledge of the research department’s forthcoming “sell” recommendation. 2. Analyze the position of the proprietary trader: The trader is separated from the sources of this MNPI by a robust and effective information barrier. The basis for the trade is documented as independent quantitative analysis. 3. Apply FINRA Rule 5270(d)(1): This rule provides a specific exception to the prohibition on front-running. It states that the prohibition shall not apply to transactions that the firm can demonstrate are unrelated to the customer block order. This includes trades for a firm’s proprietary account if the firm has implemented information barrier policies and procedures, and the individuals making the trading decision had no knowledge of the customer’s order. 4. Apply FINRA Rule 5280: This rule prohibits a member firm from purposefully establishing, increasing, decreasing, or liquidating an inventory position in a security in advance of a research report. However, similar to the front-running rule, an effective information barrier that prevents the proprietary trading desk from knowing about the content or timing of the research report serves as a valid defense. 5. Conclusion: Since the proprietary trader’s decision was based on independent analysis and they were shielded from the MNPI by an effective information barrier, their trading activity does not constitute a violation of either Rule 5270 or 5280. The key is the documented independence of the trading decision and the proven effectiveness of the firm’s information barrier policies. The existence of robust information barriers is a critical compliance mechanism for multi-service firms. These barriers, often called Chinese Walls, are designed to manage and prevent conflicts of interest and the misuse of confidential information between different departments, such as institutional trading, proprietary trading, and investment banking or research. For these barriers to be considered effective, they must be formalized in the firm’s written supervisory procedures and be subject to regular monitoring and enforcement. The burden of proof lies with the firm to demonstrate that the proprietary trade was not made on the basis of the protected information. This requires meticulous record-keeping, including documenting the rationale for trades made by the proprietary desk, to substantiate the independence of their actions. Without such a system, the firm would be presumed to be trading on the information it possesses, regardless of the department in which the trade originated.

The determination of the regulatory violation involves a step-by-step analysis of the trader’s actions against specific FINRA rules. First, we identify the nature of the information used by the trader. The trader gained advance knowledge of an imminent block transaction in INVT stock that was not yet public. This constitutes material, non-public information regarding market activity. Second, we analyze the trader’s subsequent actions. The trader executed proprietary trades for the firm’s benefit in both the underlying stock (INVT) and its related derivative instruments (call options) based on this advance knowledge. Third, we apply the relevant rules. FINRA Rule 5270, Prohibition Against Front Running of Block Transactions, explicitly prohibits a member from trading a security or a related financial instrument while in possession of material, non-public information concerning an imminent block transaction in that security. The rule’s scope includes trading for the member’s own account and covers both the underlying equity and its options. While the firm’s proprietary trading also occurred before a customer’s resting limit order, which implicates FINRA Rule 5320, the foundational violation is the misuse of the block order information. The front running action is the primary offense because it is predicated on the specific knowledge of the block trade, which is a more specific and encompassing violation in this context than the general prohibition against trading ahead of a customer. The purchase of options further cements the violation under the specific provisions of the front running rule.

The determination of whether a trade is clearly erroneous under FINRA Rule 11890 depends on the security’s price, the time of the trade, and the percentage deviation from a reference price. The reference price is the consolidated last sale price immediately preceding the transaction in question. In this scenario, the reference price is \( \$27.60 \). The trade occurred at 2:15 PM ET, which is during normal market hours and not within the special opening (pre-9:50 AM ET) or closing (post-3:35 PM ET) periods that have different guidelines. For an NMS stock priced between \( \$25.00 \) and \( \$50.00 \), the numerical guideline for a clearly erroneous transaction is a deviation of 5% from the reference price. To determine the threshold price, we calculate 5% of the reference price and subtract it: Threshold Price = Reference Price x (1 – Percentage Guideline) Threshold Price = \( \$27.60 \times (1 – 0.05) \) Threshold Price = \( \$27.60 \times 0.95 \) Threshold Price = \( \$26.22 \) The trade executed at \( \$25.95 \). Since the execution price of \( \$25.95 \) is below the calculated threshold price of \( \$26.22 \), the transaction is presumed to be clearly erroneous. The firm should submit a written complaint to FINRA Market Operations within the required timeframe, typically 30 minutes from the execution time, to have the trade reviewed for potential adjustment or nullification. The fact that the order was intended as a limit order but executed as a market order due to a glitch is the reason for the error, but the adjudication of the trade itself relies solely on the numerical guidelines set forth in the rule.

The conclusion is that a violation of FINRA Rule 5270 has occurred. The analysis proceeds as follows: 1. Identify the core prohibition of FINRA Rule 5270. The rule prohibits a member firm or its associated persons from trading a security or a related financial instrument for its own account when in possession of material, non-public information concerning an imminent block transaction in that security. 2. Establish the existence of a block transaction. Raj received a non-public order to sell 500,000 shares, which qualifies as a block transaction. The information about this order is, by definition, non-public until the order is executed and reported. 3. Evaluate the information possessed by the proprietary trader, Kenji. Kenji became aware of an imminent large sell order in INVT through two channels: an overheard conversation and a flag from an internal monitoring system. While he did not know the exact size or the client, the knowledge that a “big seller is coming” is considered material information because it could reasonably be expected to impact the short-term price of the security. The rule does not require knowledge of every specific detail of the order. 4. Analyze the proprietary trader’s action. Kenji initiated a short position in INVT for the firm’s proprietary account. This trade was on the same side of the market as the client’s block order (a sell order). 5. Connect the information to the action. Kenji’s trade was based on the material, non-public information he possessed concerning the imminent block transaction. Therefore, his actions directly fall under the prohibition of Rule 5270. The firm’s information barriers were ineffective in this instance, and the method by which Kenji obtained the information, whether through conversation or a system flag, does not provide a safe harbor from the rule. The possession of the information and the subsequent proprietary trade are the key elements of the violation.
