A buyer places a purchase order through Broker-Dealer A, and a seller places a sale order through Broker-Dealer B. After the trades are matched, both firms report net positions, and the trades are cleared and settled through a central clearing agency.
Which statement best describes the role of the clearing agency in this transaction? Answer: It acts as the buyer to every seller and the seller to every buyer, reducing settlement risk.
Clearing agency / central counterparty concept: after trades are matched, the clearing corporation interposes itself by novation, becoming the buyer to each selling member and the seller to each buying member and thereby reducing settlement risk. The clearing agency does not set member commission or markup rates; it does not review or guarantee the quality of investment advice; and it does not maintain the issuer's ownership register or transfer certificates directly between the underlying buyer and seller. Transfer agents and registrars handle ownership records.
An institutional account needs to buy 100,000 shares of a liquid NYSE-listed stock. Broker A quotes a commission of $0.01 per share and expects an average execution price $0.04 above the NBBO ask. Broker B charges no commission but expects an average execution price $0.09 above the NBBO ask. The adviser must seek best execution.
Which statement is correct? Answer: Broker A provides the better execution because its total expected cost of $5,000 is lower than Broker B's $9,000.
An investment adviser's fiduciary duty under the Investment Advisers Act of 1940 includes seeking best execution. Here, best execution is assessed by total expected cost, not by the stated commission alone: Broker A costs 100,000 × ($0.01 + $0.04) = $5,000, while Broker B costs 100,000 × $0.09 = $9,000. Because $5,000 is lower, Broker A provides the better execution. The zero commission saves only $0.01 per share and does not offset the extra $0.05 per share in expected execution price; the cost estimates are not equivalent; and splitting the order does not by itself satisfy the duty.
A portfolio manager executes a market order to buy 20,000 shares of a NYSE-listed stock. At order entry, the NBBO is $25.00 bid / $25.04 ask, with 2,000 shares displayed at the ask. The broker reports fills of 2,000 shares at $25.04, 12,000 shares at $25.06, and 6,000 shares at $25.09. The commission is $0.005 per share.
Measured against the displayed ask price at order entry, the total transaction cost attributable to this order is closest to: Answer: $640
Execution-cost analysis separates explicit costs, such as commissions, from implicit costs, such as spread and market impact. At the displayed ask of $25.04, 20,000 shares would cost $500,800; the actual fills cost $501,340, so the implicit cost is $540. The commission is $0.005 × 20,000 = $100, so the total transaction cost is $640. The $100 option reflects only the explicit commission, the $540 option reflects only the implicit price deterioration, and the $1,040 option results from using the midpoint ($25.02) rather than the displayed ask as the benchmark.
- A broker-dealer routes customer orders to a market maker that pays the firm $0.002 per share for the orders. Which of the following statements is true?
Answer: The arrangement is permissible if the firm continues to seek best execution and discloses the payments in its required reports.
Under SEC Rule 606 and FINRA Rule 5310, payment for order flow is permitted but is a conflict of interest that must be disclosed. A firm receiving payment for order flow must continue to satisfy its best-execution obligation, and the arrangement must be disclosed in the firm's required order-routing reports. The statement that the arrangement is prohibited because it conflicts with best execution is wrong: the conflict is managed through disclosure and the continuing best-execution duty. The statement that each customer must give written consent is wrong: Rule 606 requires disclosure in routing reports, not customer-specific consent. The statement that the arrangement is prohibited unless execution is at the NBBO on every order is wrong: no such condition exists; the best-execution obligation does not require NBBO execution on every order.
- Which of the following statements is true regarding a designated market maker (DMM) on a national securities exchange?
Answer: A DMM may trade for its own account to maintain a fair and orderly market, without guaranteeing a particular execution price.
Under exchange rules, a designated market maker has an affirmative obligation to maintain a fair and orderly market in its assigned securities and is permitted to buy and sell for its own account as part of that role. A DMM is not required to guarantee execution of every market order at the national best bid or offer, and it does not guarantee a particular execution price. The statement that a DMM may quote two-sided markets only when customer order flow is unbalanced is wrong because the DMM must maintain continuous two-sided quotations. The statement that a DMM may trade for its own account only to correct an imbalance in customer order flow is wrong because the DMM's proprietary trading authority is part of its broader market-making obligation and is not limited to correcting imbalances.
A portfolio manager must buy 50,000 shares by the end of the trading day. The NBBO is $50.00 bid / $50.03 ask, with 1,000 shares displayed. A patient strategy would work the order over several hours with an expected average fill near $50.02; an immediate market order is expected to average near $50.10.
Which statement correctly describes the execution-cost tradeoff? Answer: Patient trading reduces market impact but creates delay risk; immediate execution reduces delay risk but increases market impact.
Execution costs include explicit costs such as commissions and implicit costs such as the bid-ask spread, market impact and opportunity/delay risk. Working an order over time can reduce market impact, but the price may move adversely while the order remains unfilled; an immediate market order largely removes delay risk but consumes displayed liquidity and is likely to increase market impact. That tradeoff is the correct description. Immediate execution is not superior when avoiding market impact is the main concern, because immediate execution is the more impact-prone approach. Patient trading does not always produce a higher purchase cost; it incurs delay risk, but the expected fill in the stem is lower than the immediate order's expected fill. The two approaches are not identical in expected cost because the stem gives different expected average fill prices, and the asserted inclusion of commissions and spreads cannot make those expected costs equal.
An investor who expects a decline sells short 500 shares of ABC through her margin account at $80 per share. ABC will trade ex-dividend next week.
Which statement about the short sale is correct? Answer: The sale proceeds are held as collateral, the investor owes any dividend paid, and a rising stock price reduces equity.
Short-sale mechanics: the short seller sells borrowed shares and must eventually replace them. The proceeds are held as collateral in the margin account, the short seller owes any dividend to the lender, and the position loses value as the stock price rises. Maximum gain is achieved only if the stock falls to zero, but maximum loss is unlimited; short proceeds are not available as free buying power; and the dividend is owed to the lender, not credited to the short seller.
- Which statement correctly describes a possible effect of high-frequency trading on institutional execution costs?
Answer: High-frequency trading can narrow quoted spreads, but may increase adverse selection and information leakage for large institutional orders.
Market microstructure: high-frequency traders can add liquidity and tighten quoted spreads, but their ability to detect and react to institutional order flow can increase adverse selection and information leakage for large institutional orders, potentially worsening execution. The statement that high-frequency trading supplies effectively unlimited liquidity is wrong because displayed high-frequency liquidity is finite and can be withdrawn quickly. The statement that high-frequency trading is generally prohibited from trading against institutional orders on exchanges is wrong; no such general prohibition exists, and high-frequency traders may take the other side of trades. The statement that institutional orders are too large to interact with high-frequency liquidity is wrong because institutional orders are typically worked into the market in smaller pieces and can interact with high-frequency traders.
- Which of the following statements is true regarding a dark pool?
Answer: A dark pool is an alternative trading system that can match large orders without pre-trade display in the public quote stream.
Under SEC Regulation ATS, a dark pool is an alternative trading system that matches orders internally without pre-trade display in the public quote stream, allowing large orders to be executed with less market impact. The statement that a dark pool displays its best-priced orders in the public quote stream before execution is wrong because non-display is the defining feature of a dark pool. The statement that a dark pool is a national securities exchange is wrong: a dark pool is operated by a broker-dealer as an ATS, not as an exchange. The statement that a dark pool executes all trades at the national best bid or offer and does not use midpoint pricing is wrong because dark pools commonly execute at the midpoint, a price within the spread.
An investor owns 1,000 shares of a stock trading at $61 per share. To limit downside risk without accepting an execution below $55, she enters a sell stop-limit order with a stop price of $58 and a limit price of $55. The stock then gaps down and opens at $50.
Which of the following outcomes is correct? Answer: The order is triggered and becomes a sell limit at $55; with the market below $55, it will not execute.
Stop-limit order mechanics: a stop-limit order is triggered when the stop price is reached, then becomes a limit order at the limit price. The $50 opening price is below the $58 stop, so the order is triggered; because the sell limit is $55 and the current market is $50, the order is not marketable and will not execute. A trade at $55 or higher would be required for execution. The choice saying it fills at $50 describes a stop-market order, not a stop-limit order; the choice saying it is not triggered misapplies the trigger condition, since a sell stop is activated when the price is at or below the stop; the choice saying it fills at $55 treats the limit price as a guaranteed execution, which it is not.
- Which of the following statements is true regarding a cash dividend on a stock that has been sold short and remains short through the record date?
Answer: The short seller owes the lender of the borrowed shares an amount equal to the dividend, and the expected ex-dividend price decline offsets that obligation.
Under short-sale rules and stock-loan practice, the short seller is not the shareholder of record and does not receive cash dividends paid on the borrowed shares. Because the lender does not receive the issuer's dividend while the shares are out on loan, the short seller must pay the lender an amount equal to the dividend. The expected decline in the stock price on the ex-dividend date is an economic benefit to the short seller, but it is offset by the dividend obligation. The short seller is not entitled to the dividend from the issuer, does not pay the buyer of the borrowed shares, and the dividend is not held in escrow by the broker.
- Which of the following statements regarding a sell stop-limit order is true?
Answer: A sell stop-limit order becomes a limit order at the limit price once the stop is reached, filling only at that price or higher.
Under FINRA and exchange order-handling rules, a stop-limit order is elected when the stop price is reached, and it then becomes a limit order at the stated limit price, not a market order. For a sell stop-limit order, the resulting limit order can be filled only at the limit price or higher, so a fill is not guaranteed once the market has traded through the stop price. The statement that it becomes a market order and is filled at the next available price describes a plain stop order, not a stop-limit order. The statement that it remains a stop order after the stop price is reached is wrong because the order has already been converted to a limit order. The statement that it is cancelled when the market passes through both prices is wrong; if not executed, it remains a working limit order until filled, cancelled, or expired.
A customer places an order to buy 500 shares of a Nasdaq-listed stock. The broker-dealer fills the order from its own inventory at $41.50 when the independent inside market is $41.40 bid / $41.45 ask.
In this trade, the broker-dealer is acting as which of the following, and how is its compensation best described? Answer: Principal; the $0.05 above the inside ask is a markup earned as the counterparty.
Principal versus agent: when a broker-dealer sells shares from its own inventory, it is the counterparty to the customer, so the trade is as principal. The dealer's compensation is the markup, here the $0.05 difference between the customer price and the inside ask. An agent would receive a commission and would not take the other side; a markdown applies when a dealer buys from a customer below the inside bid; and the absence of a separate commission does not mean no compensation was earned.
A portfolio manager wants to sell 500,000 shares of a Nasdaq-listed stock and is concerned that a displayed order would cause other traders to move quotes before the block is completed.
Which execution venue or approach most directly addresses that concern? Answer: A dark pool or alternative trading system, where orders interact with hidden liquidity and are not displayed before execution.
Market-impact control: displayed orders can reveal size and cause liquidity providers to adjust quotes. Dark pools and alternative trading systems match orders without pre-trade display, which can reduce market impact for large blocks. A market-on-open order still participates in a public auction, a displayed limit order reveals the order, and an immediate-or-cancel order generally accesses only currently displayed interest and is unlikely to complete a block of this size.
