That is a good point about shorting, I personally haven't considered it due to fear of being on the wrong side of a call and my lack of trading expertise. It is certainly something I should look into.

Thanks for the comment!

A general rule for me is to go with the trend. If it's in a long-term down trend I'm short. If the long-term trend reverses, I am long. You can set up stop losses to prevent a bigger loss than you are comfortable taking.
