AAPL, GOOG, CDIS, WMT, ERTS, CME, are just a few I like to look at. I don't trade these live, but since I follow the YM futures contract, they look similar and are volatile enough.
LRCX looks interesting here also... I'll trade one or two from this list seems like every week during the past couple of months. SNDK, CTX, BBY, NUE(lately), CTXS, JCI, FUEL(near ER), CFC, EBAY,.... ........ rj
Almost any naz stock that has a premarket gap greater than 5 dollars and a previous volume greater than 1 million shares.
