U.S. Stocks Open Slightly Lower as Earnings Season Rolls on

U.S. stocks opened slightly lower Tuesday as earnings season hits full stride. Fitbit (FIT) shares opened lower despite revenue nearly tripling and its profits were down 33%. However, the wearables company is selling 14 million shares in a follow up public offering, diluting the value of the stock. Fitbit says the share sale will give it financial flexibility. Wall Street would like to see the money used to create new products. Tesla (TSLA) is scheduled to report quarterly results after the closing bell. The electric car maker is set to report a 4th consecutive quarterly loss. Revenue is projected to rise to $1.24 billion, a 33 percent increase from a year earlier. Analysts say they will be watching closely the production schedule of the Model X and Model S vehicles. Tesla's goal is to deliver at least 50,000 autos this year.
