$MU This trend is basically a heart-rate trading situation. The volatility in the storage chip sector right now is extremely extreme—it's almost no different from betting on a table. When it jumps upward, it can instantly surge by more than a dozen percent; when it drops, it’s also a collapse of several percentage points.

With this roller-coaster trend, be sure to watch the risks and don’t go in too heavily chasing.
