Closing-Price Buying and Unapproved Cross Trades
A dealer at a brokerage executes orders for a fund management client whose fee arrangement includes a performance fee measured against month-end net asset value. Over six consecutive trading days the client buys 180,000 to 250,000 shares of an illiquid mid-cap in the final four minutes of the session, at prices between 1.4% and 3.1% above that day's volume-weighted average price. On each day the stock closes at or near its high. Separately, the dealer has been matching the client's sell orders against a buy order from another client account at the previous day's closing price, with both clients' verbal consent recorded in the dealer's own notes but no written cross-trade approval. The firm's automated surveillance has generated alerts on both patterns. The dealer's annual bonus is linked to commission revenue.
1. Assess the closing-period buying. Is it manipulation or legitimate execution? What evidence would change your conclusion?

Start by separating intent from effect, because the pattern alone is not proof.
Pointing to manipulation: buying only in the close, consistently above the day's VWAP, concentrated in the last minutes of an illiquid stock, repeated over six days, with a performance fee struck on month-end NAV - the closing price directly determines what the manager earns. Repetition removes the one-off explanation, and the dealer's commission-linked bonus adds motive.
Pointing to legitimate execution: if the client instructs "complete the order today", or the benchmark is the closing price (index trackers and many rebalancing strategies must buy at the close), paying above VWAP is the expected cost of the strategy, not evidence of abuse.
Evidence to obtain: the client's written instruction and stated benchmark; order tickets with timestamps; the intraday order book to see whether the buying moved the price or merely followed it; whether the dealer solicited the order or chose the timing; whether the same pattern appears in other months or other client accounts; the fund's month-end NAV path; and communications between the dealer and the fund manager.
What would change the conclusion: a written instruction to trade at the close, or a closing-price benchmark, would move this from manipulation to a best-execution and disclosure question. Absent that - a dealer choosing the timing, on an illiquid name, into a fee that pays on the close - escalate to a formal investigation.
2. What is wrong with the cross trades, and what should have happened instead?
Read the worked answer
Cross trades are permitted only inside a documented policy that protects both clients. Here five things are wrong.
- No written approval. Verbal consent recorded by the person who benefits from the trade is not consent; it is the dealer's own note of his own conversation.
- Stale price. The previous close may transfer value from one client to the other, especially in an illiquid stock where the true price may be several percent away.
- Conflicting fee structures. A price favourable to the performance-fee account disadvantages the other account, and neither client can see the trade that produced it.
- Conflicts and best execution. The dealer acts for both sides and the firm earns commission on a trade that never touches the market, so best execution for each client is not demonstrably achieved.
- Priority. Client orders should not be crossed where a market order could have executed better for either side.
Correct handling: a written cross-trade policy; written consent from both clients for each trade, or a standing instruction with defined limits; a price derived from an independent reference - VWAP, the mid of the prevailing bid/offer, or an independent valuation for illiquid stock - never the prior close by default; disclosure of the cross to both clients; fair allocation of any price benefit; and a record showing the cross was at least as good as the available market alternative.
3. As compliance, what interim measures, investigation steps and reporting decisions follow from these alerts?
Read the worked answer
Immediate. Preserve records - order tickets, recordings, emails, chat, the dealer's notes - and issue a litigation hold. Place the dealer under heightened supervision; consider removing the trading mandate pending review; stop any further cross trades by that desk. Check whether other client accounts show the same closing-period pattern.
Investigate. Interview the dealer and, where possible, the fund manager. Obtain the client's written instructions. Reconstruct each day's order book to test whether the buying moved the price or followed it. Compare the fund's execution at other brokers on the same days. Quantify the effect on NAV and therefore on the performance fee. Test the cross-trade pricing against independent references for each date.
Decide and report. If the evidence supports intentional price influence, that is market manipulation and must be reported to the regulator; do not wait for certainty. A suspicious transaction report goes to the financial intelligence unit, while the conduct breach follows the firm's disciplinary and regulatory-notification process. Notify senior management and the board risk committee, and review whether the client relationship also needs action.
If the conclusion is poor execution or procedural failure without intent, the outcome is remediation, retraining, tighter cross-trade controls and possibly compensation to the affected accounts. Document every decision and its basis - the file will be read by someone who was not in the room.
