Apple's quarterly earnings report will be released today, and it's again expected to be another great quarter, thanks in large part to the new iPad and continued strong sales of the iPhone 4S. According to AppleInsider, analysts are expecting Apple to report sales of up to 30 million iPhones and 11.5 million iPads. Really, all the news is good, so why is the stock going down? It hit a peak of 644 on April 10, and now, just over two weeks later, it's trading around 558 as I write this — a drop of over 13%.
