In 'What's Ahead on Wall Street' for Wednesday Feb. 10, there are several big quarterly reports investors will be paying close attention to. In the morning, Time Warner Inc. (TWX) will report quarterly results, then in the afternoon, Cisco Systems (CSCO), Tesla Motors (TSLA), Whole Foods Market (WFM) and Twitter (TWTR) will issue results. There are several reasons why all eyes will be on Tesla. So far, shares have plunged about 40% year to date. Bearish sentiment is growing ahead of earnings due to concerns about the Model X production ramp. Some analysts say this is overdone while others say it's a valid issue. On top of this, investors are worried that Tesla's gross margins have been getting worse. For the latest quarter, Wall Street is looking for earnings of $0.08 a share on revenue of $1.79 billion.
