Stop Loss or Trailing Stop?
Posted on Thursday, April 24, 2014 at 11:00 AM
The market has moved higher, lower and higher again over the last month or so. Even though the market has rallied as of late, there's still a potential for the market to move lower. Regardless, whether the market continues to move higher or lower once again it is always a good time to talk about stop losses. Traders may hear the terms trailing stop loss and stop loss order and wonder exactly what those terms mean and how a stop loss can potentailly enhance a trading strategy. Well, worry no more because that is exactly what we will review in this blog entry.

Let's start with the basics which is defining a stop loss order. Basically, a trader will tell the broker a certain price on a stock (or option) where the position will be closed; but it's a little different than a typical closing order. For longs, the closing price is below the current market price and for shorts the stop loss closing order is above the current market. Let's take a look.
Stop Loss Example
A trader could purchase a stock for $20.00 and set a stop-loss order at $18.50. This means that the position will be closed at the market price once the stock drops below $18.50, pretty simple right? It is called a stop loss order because it stops the trader from taking any more losses. Many traders use a set percentage of a trade for a stop loss order. If a trader wants to use a stop loss order for an option, the bid and ask prices would be monitored and then the same decisions as were made in the stock example are followed.
Trailing Stop Loss Example
A trader chooses a lower target price to keep losses in check and tells the broker to sell the contract once this price is violated. There is another stop loss strategy, the trailing stop loss. A trailing stop loss is either a fixed percentage or a fixed nominal increment from the current market price. Once the market price moves away from the stop, the stop moves, or trails, the market. It remains in place, though, if the market moves towards it.
Once the trailing stop loss is triggered the stock is sold, just like the regular stop loss. The benefit of the trailing stop loss is that it is flexible. If you purchase an option for $10 and set a trailing stop of 50 cents, the sell target is $9.50. Of course, as the stock increases in value, the 50-cent trailing stop will do follow (the stock trades at $10.50, the trailing stop becomes $10.00).
A trailing stop loss can be used very effectively in profit taking and it is a strategy I have used often myself. Let's revisit the $10 stock with a 50-cent stop loss. If the company reports blow-out earnings, driving the price sharply higher, it might be time to adjust the trailing stop loss. In this example, let's say the stock jumped to $12.00. A nice profit, but there could be some more room to the upside. Maybe the trader will adjust that trailing stop a little tighter to, say, 25 cents. Doing so allows the trader to lock in a profit of at least 1.75 (12 minus 10 = 2, 2 minus 0.25 = 1.75).
Consider the option next time you are in a profitable position!
