Baird analyst Ben Kallo upgraded the rating for S&P 500 constituent Tesla Motors to "Outperform" this morning, setting a price target of $548. Kallo believes that a series of "less stellar quarters" has not shaken Tesla's stock price, indicating that investors are increasingly focusing on the company's future prospects. The recently proposed compensation plan is based on ambitious targets for product launches and market capitalization. If Tesla achieves these goals, Elon Musk may well deserve every cent of his trillion-dollar compensation package.
