Shares of Apple (NASDAQ: AAPL) took a big fall today, down by nearly 5%, which does drag down both the S&P 500 and the Nasadaq, but the Dow Jones Industrial Average (INDEX:^DJI) was up by nearly 1%. In this video, Motley Fool analyst Austin Smith talks about why it was a somewhat unusual day on the markets. Rather than seeing one or two stocks that compose a large percentage of the Dow, such as IBM (NYSE: IBM), make big moves to drive the Dow, it was just an overall good day for a lot of companies in the index, in the absence of any real macro news that would drive the market.

Austin tells us who some of the movers were today, and he cautions that on a day like this, in the absence of an overarching market driver, whatever your investment thesis was waking up this morning for any given company should be the same one you go to bed with tonight.
