Sometimes you feel awful because you just missed a trade you were following, for only a little... I just missed a +85% profit for $0.01... Yep, for just a cent!
In these cases, you need to remember to NEVER chase a stock. Just forget about it and move to the next opportunity, there are plenty of them, all the time.
As I said earlier, after 3100 resistance was broken at Shanghai, risk appetite would be back. And that was very fast because it was combined with good earnings news!
