As Tesla stock has fallen in recent weeks, members of the board and an executive at Elon Musk's company have sold off millions of dollars in stock, according to filings.

After a slight rebound earlier this week, Tesla's TSLA stock is back to falling, keeping with its recent performance. Even U.S. President Donald Trump's purchase of one hasn’t done much to spark real momentum for the electric vehicle (EV) leader.

Kimbal Musk, the brother of Tesla CEO Elon Musk, has been offloading shares of Tesla in recent months just as the stock has made a massive retreat from all-time highs. The electric vehicle maker, however briefly, had been among the select group of trillion-dollar companies following the stock’s post-U.S. presidential election surge.
