A stop-loss order (S/L) is a fundamental trading tool specifically designed to limit an investor’s loss on a security position. By setting a stop-loss order, an investor instructs the broker to sell the asset when it reaches a particular price level. The main goal is to prevent further losses beyond the investor’s risk tolerance threshold.
How Does a Stop-Loss Order Work?
A stop-loss order becomes a market order to sell once the asset reaches the designated stop price. This predefined price acts as a trigger, converting the stop-loss order into an executable order to sell at the prevailing market price.
Example of a Stop-Loss Order
- Investor Buys Shares: Suppose an investor owns shares purchased at $50 each.
- Setting the Stop-Loss: The investor places a stop-loss order at $45.
- Market Fluctuation: If the stock price drops to $45, the stop-loss order is activated.
- Sell Execution: The shares are sold at the current market price, ideally close to $45.
Types of Stop-Loss Orders
Fixed Stop-Loss Orders
A fixed stop-loss order has a predetermined stop price that does not change. This price remains constant regardless of market movements.
Trailing Stop-Loss Orders
A trailing stop-loss order adjusts the stop price as the market price of the asset moves in favor of the investor. The stop price has a predefined distance, either in percentage terms or dollar amount, from the current market price.
Special Considerations
Slippage
Slippage is a key risk in stop-loss orders. It refers to the difference between the anticipated price of a trade and the actual price at which the trade is executed. High market volatility can cause significant slippage.
Market Gaps
Market gaps occur when there is a difference between the previous day’s closing price and the next day’s opening price. In such cases, the asset might be sold at a much lower price than the stop price.
Historical Context
Stop-loss orders have been used by investors and traders for decades as a safeguard against market volatility. They have become an integral part of modern trading strategies, allowing investors to manage risk more effectively in fluctuating markets.
Comparisons and Related Terms

Market Order
A market order is an instruction to buy or sell a security immediately at the best available current price. It differs from a stop-loss order in that it is executed at the current market price without waiting for a predetermined price level.
