Apple's stock has had a big run since the market bottomed in March of 2009. Since then the stock has been riding the 10 month moving average up(I tweeted y'day the 8 month but the 10 month works too). If your an Apple investor, watch for a break below the 10 month moving average to take some profits. The monthly chart is also showing a possible "head and shoulders top" in the making. It may take another 3-12 months to make the right shoulder. In the meantime watch $585(10 month ma).
