Dave, I would not complain when the stock exceed my expectation, unless I am scared that it will give up all the gain for sure. Even if I expect the giving-up-gain is almost likely to happen, I wouldn't take action on it because that is always a slight chance that the stock will again exceed my expectations.
But if you're talking about worrying the stock going below $100, then it is a different discussion.
the Key is that you play with different stock with different approach. TSLA is so different that keeping a core position is more important than anything else. I wouldn't play with Appl in the same way right now.
In that sense, the title of this thread " short-term movemen is not a good focus for TSLA.
