SEC Investor Education Office Offers Advice on "Stop" and "Stop-Limit" Orders

Steven Lofchie Commentary by Steven Lofchie

The SEC Office of Investor Education and Advocacy ("OIEA") issued a bulletin offering advice to investors about when to use "stop" and "stop-limit" orders to buy and sell stocks.

The OIEA recommended that, when using a "stop" order, investors consider the following factors:

  • The stop price is a trigger that causes a stop order to become a market order. For that reason, the execution price for a market order received by an investor can deviate significantly from the stop price, especially in a fast-moving market where prices change rapidly.

  • A stop order could be triggered by a short-term, intraday price that might lead to an execution price that is substantially worse than the stock's closing price for the day.

  • Different brokerage firms have different standards for determining when the stop price has been reached (e.g., the last-sale price versus the quotation price).

In addition, the OIEA urged investors to keep the following factors in mind when using a "stop-limit" order:

  • The stop price is a trigger that causes a stop-limit order to become a limit order that will be executed at a specified price. As in the case of all limit orders, a stop-limit order may not be executed if the price of the stock moves away from the specified limit price.

  • Like stop orders, a stop-limit order can be triggered by a short-term, intraday price that can result in an execution price that is inferior to the stock's closing price for the day.

  • Different broker firms might have different standards for determining whether the stop price of a stop-limit order has been reached, as they might have different standards in making the same determination for a stop order.

Commentary

Firms should provide standardized educational documents to their retail clients that would clarify the mechanics and limitations of various types of orders, as well as the possible results of those orders in a volatile market.
