Though Tesla’s shares doubled over the past 12 months, they’ve had a tough run since the inauguration. Investors are waiting to see if Elon Musk can keep the company’s charmed run going.

Musk, who also runs SpaceX and a number of other companies, has been known to make big often exaggerated promises. For example, he once called the Hyperloop, which was never built, the "fifth mode of transport" and famously promised to take Tesla private in a Twitter post, saying he had secured financing that he didn't have.

Tesla Inc directors Kimbal Musk and Robyn M Denholm as well as Chief Financial Officer Vaibhav Taneja sold shares of the company over the past week, according to recent filings with the Securities and Exchange Commission.
