Summary: Stocks continued their choppy trading trend at midday Thursday. A mixed bag of earnings reports are pressuring the S&P 500 and Nasdaq into the red. Qualcomm (QCOM) is almost 12% lower after reporting disappointing results. The chip maker also cut its fiscal 2015 outlook. Investors didn't react much to pending home sales cooling off more than expected in December. Contracts to buy previously owned homes dropped .7% but that's still stronger than a year ago. We'll get a better sense of how the consumer is feeling when Amazon (AMZN) and Visa (V) report after the close. Google (GOOG) is also on tap to release. Analysts are expecting the search giant to report earnings of $7.19 a share.
