Trading is a risky business, and one of the keys to successful trading is understanding the tools of risk management. Stop loss and stop limit orders are two such tools that traders use to reduce their exposure to risk.
A stop loss order is a type of order placed with a broker in which an investor instructs the broker to automatically sell a position if it reaches a certain price. The order is most often used to place a stop on downside losses to prevent further losses. Put another way, a stop loss order will be triggered if the price of a security falls to the level specified in the order. For example, if an investor buys a stock at $50 and places a stop loss order at $45, the order will be triggered if the stock falls to $45, and the investor will be sold out of the security at that time.
The purpose of a stop loss order is to limit the risk of a trade by automatically stopping a position should it move to an undesired price. By controlling their risk in this manner, traders and investors can protect their capital and sleep soundly at night.
Stop limit orders are similar to stop loss orders, but with an important distinction. A stop limit order does not necessarily fill at the specified stop price, but will only fill at the specified limit price or better. That is, a stop limit order combines two order types--a stop and a limit order. An investor will place a stop limit order by specifying two prices: a stop price and a limit price. For example, if an investor buys a stock at $50 and places a stop limit order with a stop price of $45 and a limit price of $44, the order will be triggered if the stock falls to $45. However, rather than immediately selling the stock at $45 as with a stop loss order, the order will then become a limit order. This means that the position will only be sold once it trades at a price of $44 or lower.
The purpose of using a stop limit order is to ease the possibility of a trader getting filled at a significantly different price than was intended. Say, for example, that the stock at $50 rapidly falls to $45 and then continues to trade around that level for a period of time. With a stop loss order, the investor would be sold out at $45 before the stock stabilizes. With a stop limit order, the investor will only be sold out at $44 or lower--giving the stock time to settle at a more advantageous price.
Stop loss and stop limit orders are just two of the tools available to traders and investors looking to reduce their risk. When used correctly and modified to fit individual trading styles and objectives, they can be effective tools for limiting losses and protecting profits.
