Musk purchased 10.7 million shares on Nov. 8 and has sold 10.1 millions shares for $10.9 million

Elon Musk sold another round Tesla shares in order to satisfy his tax obligations relating to the exercise of options for buying 2.1 million shares.

According to regulatory filings, reported by Reuters, the Tesla chief executive sold 934 091 shares of electric vehicle manufacturer worth $1.01 Billion.

Musk started selling shares last month, after he asked his 60,000,000 Twitter followers if they wanted to sell some Tesla stock.

He wrote, “Much has been made recently of unrealized gains as a way to tax avoidance. So I propose selling 10% my stock.” Musk claims that 58% of respondents said yes.

The initial tweet was costly. Bloomberg reports that he lost $50 billion over the next two days due to shares falling.

Musk has sold 10.7 million shares to $10.9 billion and purchased 10.7 million shares since Nov. 8.
