What is one advantage of using a stop-loss order?

Using a stop-loss order is advantageous because it automates the process of selling an asset once it reaches a predetermined price level, thereby helping to prevent excessive losses. This mechanism allows investors to set a specific price at which their shares will be sold, which provides a safety net and reduces the need for constant monitoring of the stock's performance.

By implementing a stop-loss order, investors can protect their investment from significant downturns while also ensuring that they do not make panic-driven selling decisions during market volatility. This proactive approach helps create a disciplined investment strategy and can provide peace of mind for investors by limiting potential losses.

Other options do not accurately reflect the nature or benefits of a stop-loss order. For instance, it does not ensure profits, identify market trends, or directly improve cash flow management. Rather, its primary function is to mitigate losses, making it a critical tool for risk management in trading.
