I wish it worked that way. But it doesn't. That's like predicting if you are going to score on a first date. You just can't predict at "Hello, my name is Cockhound!" It gets better at, "Oh, Cockhound, you're so funny!" And pretty good at "Cockhound, are you as good as your name?"
Sure it does. I know, predicting specially about the future is a difficult business, but you either can or can't. Everybody can guess after a rally when the market is consolidating where it would end. Guessing at the beginning of the rally, now we are talking!
