The VWAP Order and the Proprietary Bid

A JSE member receives a discretionary VWAP instruction from a portfolio manager to buy 600,000 shares of a mid-cap over two trading days, with a volume cap of 10% of daily traded volume. The dealer also runs a proprietary book that already holds 50,000 shares. On day one, the dealer buys 120,000 shares for the client, then buys 30,000 for the proprietary book before filling the client's remaining order; the share price rises 1.8% and the client's average price is R22.15 against an arrival price of R21.80. At 14:00 the same day, another institutional client calls with an urgent sell order for 400,000 shares. Before executing that sell, the dealer sells 40,000 proprietary shares. The compliance surveillance report flags the sequence but the dealer says the proprietary trades were 'independent' and that the client order was not guaranteed.

1. Analyse the conflicts and whether the dealer's conduct breaches order-handling and market-integrity standards.

Read the worked answer

The sequence raises two separate conflicts. First, the dealer bought for the proprietary book after receiving the client's VWAP order and before completing it, in the same stock and in the same direction. That is classic front-running risk: the proprietary trade can move the price against the client and benefits from the client's anticipated demand. Even if the trades were 'independent', the timing and direction create an inference that the client order was exploited. Second, selling proprietary shares immediately before executing a large client sell order avoids loss at the client's expense. The dealer's claim that the client order was not guaranteed misses the point: the duty is to handle the client order fairly and not to trade ahead of it. Best execution also requires the member to consider price, cost, speed and likelihood of execution; a 35-cent slippage against arrival needs explanation. Volume caps and VWAP instructions do not authorise proprietary front-running. Market-integrity standards prohibit misleading or abusive conduct, and the firm's surveillance should treat repeated patterns as potential market abuse, not just a conflict.

2. What should compliance do with the surveillance alert and what controls should be introduced?

Read the worked answer

Compliance should not close the alert with a dealer explanation. It should preserve order and trade logs, proprietary book records, recordings and chats, and reconstruct the timeline. It should test whether the proprietary trades were pre-planned, whether the dealer knew of the client orders, and whether other clients were affected. The matter should be escalated to the JSE and, if there is a suspicion of market abuse, considered for reporting to the FSCA. Pending investigation, the dealer should be restricted from trading the stock and from handling the affected client orders. Client remediation may be required if the client's execution was disadvantaged. Controls should include a mandatory no-proprietary-trading restriction in stocks with pending client orders, a watchlist and restricted list, pre-trade checks that compare proprietary orders against the client order book, surveillance scenarios for front-running and 'sell ahead of client sell', and independent review of VWAP executions. The firm should also review remuneration and incentives that reward proprietary profit.

3. How should the client's VWAP order have been handled to manage the conflict?

Read the worked answer

The order should have been handled under a documented conflict-management plan. Before accepting the VWAP instruction, the desk should have disclosed the proprietary position and either ring-fenced the stock, obtained consent to trade alongside, or declined the mandate. Execution should have been sequenced so that client orders are completed before any proprietary order in the same direction, unless a written policy permits otherwise and the client is not disadvantaged. The dealer should not have used knowledge of the client's pending sell to sell proprietary first. A central order book with time-stamped client and proprietary orders, and a rule that proprietary orders cannot jump ahead of unexecuted client orders, would have made the conduct visible. The client's average price and arrival price should be independently reviewed, and any slippage attributable to the proprietary trades should be remediated. The firm should document the conflict decision and provide the client with clear disclosure of the execution arrangement.
