With the stock sporting a triple-digit price-to-earnings ratio (and that's on a forward-looking basis), the case for buying Tesla before its July earnings report just isn't there. Any new investor is betting big on the company's ability to deliver on its bold promises -- I'm not confident it can.

The Wall Street Journal, citing people familiar with the situation, on Tuesday reported that Troy Jones, who on his LinkedIn page is described as a vice president of sales and service in North America, has left Tesla after a 15-year run with the EV maker. Tesla did not respond to a request for comment in time for publication.
