As earnings continue to flood the markets this week, traders struggle to find any consistent trend. The markets were mixed yet again today as earnings beats and misses play tug of war with the broad based indices. The Dow 30 was down 25, the S&P 500 was flat, and the Nasdaq 100 added 12. 

The big focus from here that will steal the media headlines will be Apples (AAPL  ) earnings release scheduled for after the close today. There are many opinions as to the results and analysts opinions are basically split between bullish and bearish.
