DATA stock is up 15.3% to trade at $121.08, earlier hitting a three-year peak of $123.88 -- and has added almost 28% since bouncing from its 200-day moving average in late October.

The shares Michael Kors Holdings Ltd (NYSE:KORS) are wallowing near the bottom of the Big Board, after the retailer reported a quarterly revenue miss and same-store sales slump. After tagging a new annual low out of the gate, KORS stock was last seen down 15.5% to trade at $48.53.
