Not speaking for stockjocky, but a couple of reasons I can think of to do that.
- Stops/Trailing-stops aren't foolproof, in a stock as volatile, & sometimes illiquid as these pennies, once it's really falling, your order may not execute at your price. It could end up way lower.
You want to be selling on the way up, while there are still buyers.
- Some of these promos, go up 100% - 1000%, some never go up at all, many go up 20% - 30% then go down, never to return.
Wise to take your 30% profit, & be ready for your next play, better to miss some of the possible upside than take a big loss.
