Tesla Inc Chief Executive Officer Elon Musk has sold 19.5 million shares of the electric vehicle maker worth $3.95 billion, US securities filings showed on Tuesday.
The latest sale brings the total value of Tesla stocks sold by Musk to nearly $20 bln since he disclosed his stake in twitter in April.
Musk sold a combined $15.4 billion worth of Tesla shares in April and August, but had said there were no further sales planned.
Musk, the world's richest person, took over Twitter in a $44 billion deal last month and has engaged in drastic measures including sacking half the staff and a plan to charge for blue check verification marks.
