Marking The Close

A trader enters a series of small trades near the close of trading specifically intended to move the closing price of a thinly traded stock to a more favorable level for a position held elsewhere. What must the principal recognize about this activity?

1. A.Refer the matter to the trading desk for a discussion about trade timing best practicesWrong. This understates the seriousness of intentional price manipulation, treating it as a matter of timing preference rather than a violation.
2. B.Nothing, since trades near the close are a routine part of market activityWrong. This mischaracterizes trades specifically intended to manipulate the closing price as routine activity.
3. C.Recognize this as marking the close, a manipulative practice requiring investigation and escalationCorrect. Trades specifically intended to influence the closing price constitute marking the close, a serious manipulative practice.
4. D.Nothing, as long as the trades individually complied with applicable order size limitsWrong. Compliance with order size limits does not address the manipulative intent and effect on the closing price.

Why: This is marking the close, a manipulative practice intended to influence the closing price rather than reflecting genuine trading interest. The principal must recognize this as a serious violation requiring investigation and escalation, not treat it as an aggressive but permissible trading strategy.

In the final minute of trading, a trader enters a series of small buy orders in a thinly traded stock solely to push its closing price higher and flatter his fund's month-end valuation. This activity is:

1. A.Front-runningFront-running is trading ahead of a known customer order or pending information - no such order exists here.
2. B.A bona fide market-on-close strategyMOC orders seek the closing price honestly; these orders exist to move it.
3. C.Marking the close - manipulating the closing price with late-session ordersCorrect - trading to paint the official close is classic manipulation.
4. D.Permissible window dressing of the portfolioWindow dressing describes changing holdings before reporting dates - it does not license manipulating prices.

Why: Executing trades near the close to influence the official closing price is marking the close, a manipulative practice. The intent - moving the reported price rather than acquiring an investment - is what makes it manipulation. The clue is solely to push the closing price. Review: prohibited trading practices.

In the final minutes of the trading session, a trader who holds a large long position in a thinly traded stock enters a series of small buy orders with no apparent economic purpose other than pushing the print higher just before the close. A principal reviewing end-of-day trading activity notices the pattern. What should she conclude?

1. A.This is marking the close: entering orders near the session's end for the purpose of influencing the closing price rather than a genuine trading purpose.Correct. Purpose-driven orders near the close intended to move the print are a manipulative practice.
2. B.There is no concern because the orders were too small individually to move the price of a normal stock.Wrong. In a thinly traded name even small orders can move the print, and the concern is the manipulative purpose, not the size of any one order.
3. C.The activity is acceptable because it occurred during normal exchange trading hours.Wrong. Trading during normal hours doesn't excuse a manipulative purpose behind the orders.
4. D.The concern applies only if the trader's position was disclosed publicly as a large holding.Wrong. Whether the position is publicly disclosed has no bearing on whether marking the close occurred.

Why: Entering orders near the close for the purpose of influencing the closing price rather than for any genuine investment purpose is marking the close, a manipulative practice; the principal must escalate and investigate the trader's activity rather than treat it as ordinary late-day trading.

A firm's trade surveillance program for manipulative activity is built to review trades tied to customer complaints, but proprietary trading activity that generates no customer complaint is never independently reviewed for signs of manipulation. A principal is asked whether this surveillance design is adequate. What should she conclude?

1. A.The design is adequate, since manipulation surveillance exists primarily to protect customers who complain about their executions.Wrong. Manipulative practices like marking the close or wash trading often involve no customer order at all, so a complaint-driven trigger misses them entirely.
2. B.The design is inadequate; surveillance for manipulative practices must independently cover proprietary trading activity, not rely on customer complaints as a trigger.Correct. Manipulation surveillance must cover proprietary trading independent of any customer complaint trigger.
3. C.The design is adequate as long as proprietary traders separately certify their own compliance with trading rules.Wrong. Self-certification by the traders being surveilled is not a substitute for independent surveillance review.
4. D.The gap only matters for firms that do not also maintain a separate best execution review process.Wrong. A best execution review addresses different obligations and does not fill the gap in manipulation surveillance over proprietary trading.

Why: Surveillance for manipulative trading practices such as marking the close, wash trades, and spoofing must cover the firm's own proprietary trading activity, since a customer complaint is not a prerequisite for — and often has no connection to — this kind of manipulation; limiting review to complaint-driven trades leaves the firm's own trading essentially unsupervised for these practices.
