Shares of Tesla plunged more than 9 percent Friday after news of a pair of C-suite executive resignations and a bizarre video showing CEO Elon Musk smoking pot on a podcast, capping a tumultuous month since Musk launched the company into controversy with a take-private tweet.

The stock opened Friday's session at $260.10, extending a painful week for the automaker. As of Thursday's close, the stock had already lost 7 percent on the week.
