Be sure you have an exit strategy.
Selling part of your holding as it moves upward (scaling out) is always a nice way to avg out of a position once it has achieved targets or minimum targets, such as my 25 goal area I set last week. Otherwise set stop-losses to lock in profits while trailing the performance (hence perhaps setting trailing-stop-loss, etc.)
