The way I like to play it if I really like a stock start a smaller position and then wait for a pullback.But if it starts running I will add chuncks here and there. There will definetly be some pullbacks along the way but the risk you take by not at least starting a small position is the next time it pulls back it may be up to 2 or 3 cents. I've seen several people in the last week or so that have been waiting for another pullback. That's only my opinion.
