This is a big issue as these indexes that everyone follows are now heavily weighted withe a few of the high flier stocks, like Apple. If those companies stumble, the entire market will fall with them. It's ironic that much of the gain we've seen the past several years has come on the backs of a couple dozen companies and now we're going to see the impact of that.
Sure feels like we're right back where we were in 2007 before the bottom fell out last time. Hope I'm wrong, but sure feels similar.
