Difficulty: HardTypes of Orders and Order Execution Strategies

An investor places a Good-'Til-Canceled (GTC) Buy Stop-Limit order for 500 shares of XYZ stock at $50\$50 Stop, $52\$52 Limit when XYZ is trading at $45\$45 per share. Shortly thereafter, unexpected bad news causes the stock to fall to $40\$40. Two weeks later, positive earnings news causes the stock to open after a morning trading halt at $53\$53 per share, and it trades strictly between $53\$53 and $56\$56 throughout the remainder of the trading session. Which of the following statements correctly describes the status and execution of the investor's order?

  1. The order was triggered when the stock opened at $53\$53, converting it into a buy limit order at $52\$52, but it remains unexecuted because the stock never traded at or below $52\$52.Answer
  2. B
    The order was executed as a market order at the opening price of $53\$53 because breaching the $50\$50 trigger price guaranteed immediate execution.
  3. C
    The order was automatically canceled when the stock price dropped to $40\$40 because GTC stop orders expire if the market price moves more than 10%10\% away from the stop price.
  4. D
    The broker-dealer executed the order as a principal trading from its own inventory at $50\$50 to avoid commission fees for the customer during the trading halt.

Answer

The order was activated when the stock opened at $53\$53, becoming a limit order to buy at $52\$52, but it remains unexecuted because the stock never traded at or below $52\$52.
A Buy Stop-Limit order involves two distinct price components: the stop trigger price and the limit execution price. For a Buy Stop-Limit order placed at $50\$50 Stop, $52\$52 Limit, the order remains inactive while the stock trades below $50\$50. When the stock gaps up and opens at $53\$53, the stop condition ($50\ge \$50) is met, activating the order. Upon activation, it becomes a standard Buy Limit order at $52\$52, meaning the investor is willing to buy only at $52\$52 or lower. Because the stock trades strictly between $53\$53 and $56\$56 for the rest of the day, the market price never reaches $52\$52 or lower, leaving the order active but unexecuted.

Step-by-Step Solution

1
Evaluate the order placement conditions and market movements prior to activation.
The Buy Stop price is $50\$50. When the stock drops to $40\$40, the stop instruction is not triggered because a Buy Stop requires a trade or quote at or above $50\$50.
Buy stop orders are placed above the current market price and require price appreciation to trigger.
2
Determine if the opening price after the trading halt activates the stop condition.
The stock opens at $53\$53, which is $50\ge \$50. The Buy Stop is activated/triggered.
Any trade or quotation at or above the stop price activates a buy stop order.
3
Analyze the execution parameter of the activated order.
Once activated, the Buy Stop-Limit order becomes a Buy Limit order at $52\$52. A Buy Limit order can ONLY be executed at $52\$52 or lower (better).
Limit orders specify a maximum purchase price (or minimum selling price).
4
Compare the market price range throughout the trading session against the limit price.
The stock trades between $53\$53 and $56\$56, never reaching $52\$52 or lower. Thus, the order remains unexecuted.
A limit order to buy at $52\$52 cannot be filled when market prices remain strictly above $52\$52.
