Because that's the way the market works these days. Stocks always overreact to both the upside and downside.
I'm not going to argue with you any longer about share price or the tit for tat going on. I have better things to do with my time, and anyone who reads the SEC filings understands everything they need to know.
You can get caught up in the day to day share price movements if that's interesting to you, or you think you can make money trading in/out day to day - you do this, you've said so, and I have no doubt that you will continue to. Whatever you post is a simple indication of how you are looking to trade in the next few days. If that works for you, more power to you.
