Sounds like you don't know your own risk tolerance? If the swings are too much you should probably sell out to Andrew Left's group … that's exactly what they want you to do.
Investing is a long term game and any good investor will tell you that. If your pain tolerance is low, which it sounds like, I would recommend looking at trading quarterly (3 months) or even longer.. This is a brand new market = high volatility. We go legal tomorrow so of course the shorts are going to try to squeeze out more shares before in the month leading up to it. Know what you own and do DD. It will continue to have high volatility until we get into next year and earning keep increasing.
