Whats a trailing stop and when is it helpful. If you bought Nvidia or any other stock and it is going on a tear upwards and you want to lock in profits, a trailing stop can be a helpful tactic to use to lock in the most profit that you can. Thanks to @Danielle Christian L for raising Nvidia and to @magnumv8driver for raising the trailing stop. There are pros and cons to trailing stops but in certain scenarios it can be useful depending on your goals. #trailingstop #fyp #investing #nvidia #traili
