What is a stop-loss order?

A stop-loss order is an instruction placed with a broker to sell a security when its price falls to a designated level, known as the stop price. Once this price is hit, the tool automatically triggers an order to sell the security. In some trading strategies, such as short selling, it can also be used to buy a stock back if the price rises beyond a certain point.

By predefining exit levels, stop-loss orders can help investors potentially manage downside risk and reduce the impact of emotional decision-making.

How a stop-loss order works

In practice, a stop-loss order works as follows:

• Set a stop price below the current market level to potentially limit losses.
• When the stop price is reached, the order converts into a sell instruction.
• For a stop-market order, execution happens at the next available price.
• For a stop-limit order, execution only occurs within defined price boundaries.
• Traders may adjust stop-loss levels as part of ongoing risk control strategies.

Types of stop-loss orders

There are two commonly used types of stop-loss orders:

• Stop-loss limit order: A stop-loss limit order is used to buy or sell the stock at a specific price or within a defined price range. For example, if you bought a stock at Rs. 100, you might place a stop-loss limit order at Rs. 95. If the stock price reaches Rs. 95, the stop-loss order will be triggered, but trade will only happen if you find a buyer willing to pay Rs. 95 or more. The risk here is that if no buyer is available at that price, your order might remain unfulfilled or only partially executed.
• Stop-loss market order: A stop-loss market order is used to buy or sell the stock at the best available price once the stop level is triggered. So, if your stop price is Rs. 95 and the stock drops sharply, your order will be triggered and sold at the next available market price, which could be Rs. 94.80 or lower, depending on liquidity. While you may not control the price, the order is more likely to go through.

Advantages and disadvantages of using a stop-loss order

A stop-loss order has potential benefits and limitations that investors should be aware of:

Pros:

• Automates risk control and reduces emotional decision-making
• Helps limit potential loss without the need for constant monitoring
• Can be integrated into algorithmic and momentum-based strategies

Cons:

• May be executed at an unfavourable price in fast-moving or illiquid markets
• Does not guarantee a specific execution price during price gaps
• Can be triggered prematurely in volatile or choppy trading conditions (also known as whipsaw risk)

Importance of stop-loss orders

The importance of stop-loss orders has increased as retail and app-based trading have become more common. For investors who are unable to track markets during the day, stop-loss orders can introduce a degree of risk mitigation. For those pairing direct equity investments with mutual funds, stop-loss mechanisms can offer tactical discipline that supports broader financial goals.

Limitations

Stop-loss orders depend heavily on market liquidity. In thinly traded stocks, there may not be sufficient buyers or sellers at the stop price. This can result in slippage—where the executed price is lower than expected.

Additionally, temporary price spikes or dips can trigger a stop-loss, only for the stock to recover shortly after. Since stop-loss orders are placed with the broker, platform outages or delays during volatile periods may also affect execution.

Conclusion

Stop-loss orders are not just trade instructions—they form part of a structured risk-management strategy. By predefining when to exit a position, they help investors navigate volatility while limiting potential losses.

In mutual funds, too, fund managers may use similar risk mitigation strategies. Understanding these can help investors get better insight into how their portfolio is being handled.

Investors are advised to consult a certified financial advisor before making any investment decisions.
