Not me. I got out of my "short the market/make money when the market goes down stock" because I was losing money.
Normally what I do, is, by using Scottrade, I look at what has either gone up big or gone down big and then watch them on a chart. If the one that goes up is holding it's position, I might buy some and just watch it closely, like I did on Friday. Or, I might see something that went down big, but then is quickly going back up. That one is a lot more risky and definitely has to be watched real close.
