AAPL is another to keep a close eye on

Over the last several month and really over all of 2012, the market has had difficulty holding large losses of over 1% in the a.m. trade.

AAPL just broke a support level and I mean just broke it, triggered a bunch of stops and thus is worth keeping a close eye on.

 On a daily chart it is a very slight break, almost imperceptible

On a 1 min chart, there's the trendline for support, note the volume pick up as it is broken as traders still use EXACT support and resistance numbers.
