NEW YORK (Real Money) -- Every dog in this market does have its day. At least that's what it seems like when I look at what was running, that is, the biggest percentage gainers in the S&P 500.

Take the leader of the pack, Micron (MU), the low-cost DRAM and flash memory producer that had been so much higher but has been sliced by 50% because supply finally overtook demand in its core products.
