Tesla is what stock market pundits call a “story stock.” But, in fact, there’s more than one story here, and there are several very different reasons to invest, or not invest, in the innovative automaker. Some boosters want to be part of Elon Musk’s bold mission to change the world, while others simply see a company with meteoric growth and fanatical brand loyalty. Some skeptics point to the unlikelihood of a small startup scaling the auto industry’s proverbially punishing barriers to entry, while others just can’t get past Musk’s unconventional personality and snarky tweets.
