Low volume tends to exacerbate any moves, and I think on Friday everyone on Wall Street is going to have skeleton crews on staff.
It's a pretty good rally today but not tremendously strong. The breadth is good, but I'd like to see the volume a bit stronger.
I wouldn't discount the likelihood that next week will be flat to lower. It's a holiday week, volume will be light, and after four up weeks we'll need a pause.
We're primarily up because we're oversold and oil is down. The breadth is decent, but the volume is low. There's just not much of a catalyst to move us.
