Stop-Loss Order
An instruction to sell a security when it reaches a specified price, automatically limiting the investor's loss on a position.
01—What is Stop-Loss Order?
The definition — and what it means in practice.
A stop-loss order is an instruction to sell a security once its price reaches a pre-set “stop” level. When the stop price is touched, the order is triggered and sent for execution, aiming to cap the loss on an existing holding. It is commonly used as a risk-control tool for long positions. A stop-loss focuses on price, not on company fundamentals or time held.
Stop-loss orders matter because market moves can be fast, and you may not be watching the screen during trading hours. By deciding your exit level in advance, you reduce the chance that a small decline becomes a much larger loss. It also helps enforce discipline: you define the maximum downside you are willing to tolerate per share, then let the order handle execution when the market reaches that level.
If you bought at Rs 100 and set a stop-loss at Rs 90, your sell instruction triggers if the price falls to Rs 90, helping limit your loss.
- A stop-loss is an automatic sell trigger set at a chosen price level.
- It is designed to limit downside on an existing position, not to maximise profits.
- The trigger price is your choice; execution depends on available liquidity at that time.
- Using stops can reduce emotion-driven decisions during volatile moves.
02—How stop-loss order works on the PSX
The Pakistan-specific rules, conventions, and numbers.
On the Pakistan Stock Exchange (PSX), a stop-loss is a practical way to manage risk when you cannot monitor prices throughout the trading day. You place the instruction through your broker’s trading system, and it triggers when the specified price level is reached during market hours. This is especially relevant for retail investors who may trade alongside work or other commitments.
Daily price limits (circuit breakers) on most PSX equities are typically ±10% or Re 1 around the previous close (LDCP), whichever is higher. That means a stock may not trade beyond its limit in a single session, which can affect how quickly a stop level is reached. Even when triggered, the sale still depends on normal trading in the market and the available buyers at the time.
03—Common misconceptions
Where investors most often get this wrong.
A stop-loss guarantees I will sell exactly at my stop price.
A stop-loss triggers a sell when the stop level is reached, but the actual execution can differ depending on liquidity and order matching.
Stop-loss orders are only for short-term traders.
Long-term investors can also use them as a risk-management tool to cap downside on specific holdings, especially in volatile periods.
Setting a stop-loss removes all risk from the position.
A stop-loss can limit losses, but it cannot eliminate market risk. Prices can move quickly and execution depends on trading conditions.
