The Stop-Limit Order — A Stop-Loss That Protects the Price
A stop order can sell at an unwanted bargain price. So can't you nail it down and say 'never sell below this price'? That is exactly the stop-limit.
What the Stop-Limit Is
A stop-limit order combines a stop order and a limit order.
According to the SEC, when the price hits the stop price, the order is triggered — but at that point it converts not to a 'market order' but to a limit order at a preset 'limit price.'
That is, it executes only at the limit price or better. In exchange for controlling the price, it may not execute at all if the conditions are not met.
The Decisive Difference From a Stop Order
The difference between the two orders is 'what it converts into after being triggered.'
- Stop order -> market order. It prioritizes execution, so it definitely sells, but the price can turn out worse. - Stop-limit order -> limit order. It protects the price, but in a plunge it will not execute below the limit price, so the position can remain unsold.
One is 'execution first,' the other is 'price first.'
The Trade-Off in an Example
Say you set a stop-limit of 'stop $40, limit $39' on a $50 stock.
1. When the price hits $40, it is triggered. 2. Selling is attempted only at $39 or above. 3. If a gap-down sends the price plummeting to $37 in an instant, the $39 limit does not execute and the stock remains held.
The result is that you prevented a 'bargain sale' but took on the opposite risk of a 'failed stop-loss.' Which is better depends on the situation, and the key is to choose while understanding both risks.
The stop-limit, which tries to protect the price, carries the risk of the stop-loss failing to execute in a plunging market. No order eliminates loss entirely, and this article does not recommend any specific order method.
よくある質問
Q. Is a stop-limit always better than a stop order?
No. You can protect the price, but in a plunge it will not execute below the limit price, so the stop-loss itself can fall through. 'Price control' and 'certain execution' are things you must trade off against each other.
Q. Can I set the stop price and limit price the same?
If you set them equal, at the moment of triggering you cannot catch volume below that price, raising the risk of non-execution. Usually the limit price is set slightly below the stop to leave room for execution, but that means accepting corresponding slippage.
