I trade only major sure moves. I do a lot of goog as of recent. Usually when they go way up or way down I go reverse the next day. I do between 900 to 1,000 shares. Normally it is about twice a week. I have never lost a penny since I have been playing with this stock. Its swings are very predictable.
If there is any news of financial misconduct on any stock I always get a quick short out of it.
