vipetrul,

The question of when to sell depends on when you bought. At what price did you enter the trade? Where was your stop (either mental or actual) when you entered the trade? Is the current profit at least double your original risk?

Usually questions of this nature are looking for some kind of advice to relieve anxiety/fear. It does not help your current situation, but I strongly encourage you to enter future trades with a predetermined game plan. No football team says "go deep" on every down. They have a whole playbook before they ever set foot on the field.

The great thing about stocks is that nobody trades a single share. Usually even small traders own 50+ shares. I generally dump 1/3 - 1/2 of my position if I get an itchy trigger finger. It helps me lock in some mental profits, calm down and assess the situation more clearly.
