Market timing is fun to play, but hard to make serious money, unless you take on a lot risk by leveraging up. The right way to make big buck is to study a company, do your home work, then buy and hold. 校长当年捡了一棵小黑梅,种到后院里,现在还没舍得吃呢.当初要是吃了,可就亏大发了. So I play market timing game a few times a year, just for fun!
