I have no problem changing my mind on a dime. In fact, the stock market is one of the only places where being a "flip-flopper" is a good thing!
This morning I bought 100 shares of FB for $65.31. I'm riding this thing to $70, potentially higher. In addition to this stock swing trade, I set up a credit put spread as well. Specifically I sold a 64.50/64 weekly put spread that expires on Friday. In all I collected $100 of premium on this trade. I think it's safe to say FB will be ABOVE $64.50 by the end of the week.
