Micron Technology (MU) released its fiscal third-quarter numbers yesterday after the bell. Today, the stock is doing horribly. During the afternoon trading session, shares were off by well over 12%.

Of course, one wonders: is this a buying opportunity? According to TheFly, Wedbush thinks so. As for me, I'm not so certain. Yes, I look at the sell-off, and I recognize the potential for a next-day bounce, or a bounce a few days from now. It happens.
