We just finished the worst month we've had in seven years. Last week was a particularly bad week, with the S&P being off about 2.5 percent and a lot of people being on vacation. It just sets the stage for a bit of a bounce back today.
Now there would be a lot of people that would argue they are worth it. I would say, okay, maybe they are. But, gosh, if there's a stumble... if you're trading at more than twice your growth rate... the down side becomes horrific.
