As discussed yesterday, AAPL was the main stock I watched today for clues whether the market will hold up today. Sure enough, after a failed sell-off attempt late morning, AAPL spent the second half of the afternoon letting sellers dictate the market. Technically today's price action was pretty meaningless for AAPL as well as for the overall market, but it paid to watch AAPL nevertheless so as not to buy into an overextended market.
