Stop Loss

Stop Loss is a pre-determined price level at which a trader or investor exits a losing trade to prevent further losses.

It is a risk management tool that automatically triggers a sell order when a stock falls to a specified price. Instead of emotionally holding a losing position hoping for a recovery, a stop loss enforces disciplined risk management. Stop losses are essential for both intraday traders and long-term investors. What is a Stop Loss? Suppose you buy a stock at ₹500 and set a stop loss at ₹475 (5% below your buy price). If the stock falls to ₹475, your stop loss order is triggered and the position is automatically sold, limiting your loss to 5% (₹25 per share). Without a stop loss, the stock could fall to ₹300 and your loss would be 40% — a loss far beyond your original risk tolerance. There are two types of stop losses. A "sell stop" (more common) triggers a sell when the price falls to or below your stop level. A "buy stop" triggers a buy when the price rises to or above your specified level (used to enter a stock that is breaking out upward). Most retail investors use sell stops. Setting the right stop loss level is both an art and a science. Too tight (e.g., 1% below your buy price) and normal market volatility will trigger the stop before the stock has a chance to move in your favour. Too wide (e.g., 20% below) and your risk per trade becomes very large. Common approaches include: setting stop loss below recent support levels (₹480 if ₹485 was a support), using a percentage of your risk tolerance (2% of portfolio per trade), or using the Average True Range (ATR) indicator. In intraday trading, stop losses are typically kept tight — 0.5% to 2% of the buy price. In delivery-based investing, stop losses are wider — 15% to 25% — because short-term volatility is expected and the investor is betting on long-term value. A delivery investor buying a stock fundamentally believed to be worth ₹1,000 at ₹800 should set a mental stop loss at ₹650 (the level at which the fundamental thesis would be proven wrong). Stop losses do not guarantee execution at the specified price in fast-moving markets. In a gap-down opening (like the March 2020 COVID crash when Nifty opened 15% lower), a stop loss at ₹470 on a stock bought at ₹500 would be triggered at the open, possibly executing at ₹440 or lower. This is called "slippage." To mitigate this, traders use "stop-loss market orders" (triggers a market sell at the stop level) or "stop-loss limit orders" (triggers a limit sell at the stop price or better). Always understand how your broker's stop-loss order type works before placing it.
