Day trading AAPL is like milking a cow for me -- it just keeps on giving. It has everything you could want for day trading: volatility, liquidity, easily shortable, and -- most important of all, it trends strongly. Just wait for basic technical patterns (e.g., today at about 3PM EST it began to break down on strong relative volume) and jump on board. FYI, my basic filter is: NASDAQ Average True Range(10) > 1.35 Close > 10 Close < 80 Average Volume(90) > 3000000 This gives: AAPL BRCM SNDK NVID MRVL ERTS GILD But AAPL is, for me, much easier to pick off technically. Anyone else have a favorite cash cow?
