I have never shorted a penny, nor will I ever. As the risk is too great. Your downside is limitless and your upside limited to the price (rather small) of the share. Why would I put myself in such a situation. Surely that cannot be rational.

Your strategy may be right 99 of the time. It may feel good pocketing profit afer profit. That may strengthen your resolve to continue following your system. But on your hundredth trade you may loose 20 times what you have previously made in all your trades.

I am the the biggest skeptic around. I don't believe the news and think listening to it makes people stupid. But I also know that the one time out of a hundred the news is right the result is going to be so big that it could bankrupt me if I had short exposure.

You CANNOT know everything. You can limit your downside.
