bearish markets

I hate to be one of those guys seen as an alarmist of perma-bear.  Trust me, I prefer bullish markets and going long. I just do not see things at the moment as anything other than bearish. The last domino standing are the U.S. stocks, some of which are already feeling a change in direction. 

Not wanting to be seen as a "the sky is falling type", but I've been concerned for months and suggest, if you are going to go long, be careful.
