Morgan Stanley analyst Adam Jonas maintains an 'overweight' rating on Tesla stock with a price target of $400. He believes that the lines between the automobile and mobile device market will blur as cars become increasingly defined by their software. This could have implications for Tesla, as the company's future may depend on expanding beyond just selling cars. Jonas also noted that Tesla vehicles have often been described as iPhones on wheels, and rumors of Tesla's own smartphone project have circulated for some time.
