What I've heard is that all the "smart money" and institutional investors sold the bottom in March and are going crazy watching a rally they missed. There is a lot of cash ready to come in on a pullback, and then the rally will continue. I wouldn't sell SYX anyway. It is underpriced.
But I think it is related to the market more than to SYX itself. The whole computer retail sector was lagging when the market was surging. So my reasoning is that in a declining market and with such bad unemployment numbers - I see nothing but a continuing down turn.
Articles in Barron's have indicated this week is critical for determing the market direction for the next couple of months.
