Tesla boss Elon Musk has sold shares in his group again.

The entrepreneur sold a little more than 934,000 papers for 906 million US dollars, according to mandatory reports to the US Securities and Exchange Commission on Tuesday night.

This means that Musk has already sold a total of almost 12 million Tesla shares worth a good 12.7 billion dollars (11.25 billion euros) since he sold ten percent of his 17 percent stake in a Twitter vote in early November at the electric car maker.

Musk had Twitter users vote whether he should part with ten percent of his Tesla stake in order to pay more taxes.

To achieve this goal, Musk has to sell more Tesla shares.

The 10 percent corresponds to around 17 million Tesla shares.

Musk is Tesla's largest single shareholder.

Tesla stock has come under pressure since Musk began selling shares in early November, losing 21 percent in value from its November 4th high.

The annual growth is currently 37 percent.

The wealth of the Tesla boss is according to Bloomberg calculations at 254 billion dollars.

Musk's wealth is largely based on owning stocks, which are not taxed until sold.
