cartechboy (2660665) writes "Elon Musk is the CEO and founder of both Tesla Motors and Space X, and in the past he was the founder and CEO of PayPal. You might say he's a busy guy. Tesla seems to be doing quite well these days, but one bond trader thinks Elon should quit making electric cars and should focus his efforts on making batteries. Bond manager Jeffrey Gundlach believes the "killer" return speculative investors could get from Tesla becoming a battery-only business. Gundlach says he's already tried to meet with Musk to persuade him to take the battery-only route. Speaking to Bloomberg, he said Tesla could be "wildly transformational" in the same way electricity and electromagnets were at the advent of their discovery. With strong demand, it seems people are interested in Tesla's vehicles which leads me to believe Elon won't take Gundlach's advice. Should he?"
