NEW YORK: For a few tumultuous years, Tesla Inc gave the bulls reason to believe and bears reason to doubt. Sure, Elon Musk was pulling off what legacy automakers tried and failed to do - make electric cars cool - but he was presiding over an inexperienced enterprise, and the old guard would catch up.
As Tesla observers try to understand how and why the stock has tripled in a little more than three months, analysts and Musk’s own rivals are second-guessing the notion that the Model 3 maker will be caught anytime soon.
