Austin, Texas - Tesla boss Elon Musk has sold another batch of shares – this time worth $3.6 billion – in the electric vehicle manufacturer, a filing with the US Securities and Exchange Commission revealed on Thursday.

Over a period of three days ended December 14, Musk sold 22 million shares in Tesla.

Following the news, Tesla stock went down around 3% on Wednesday's regular trading, and sunk a further 3.2% in pre-market trading on Nasdaq on Thursday.

In the middle of the stake sale, Musk on Tuesday tweeted, "At risk of stating obvious, beware of debt in turbulent macroeconomic conditions, especially when Fed keeps raising rates."

This is the second time that Musk has sold his Tesla shares after the $44 billion Twitter purchase in October. In November also, Musk sold 19.5 million shares worth $3.95 billion partly to fund his Twitter deal.

Musk, who remains the largest shareholder in Tesla with 13.4% stake, in April this year had sold billions worth of Tesla shares, but said then in a tweet that, "No further TSLA sales planned after today."

However, in August, Musk sold around 7.9 million shares in Tesla reportedly worth around $6.88 billion.

He was then facing a legal battle for his intended withdrawal from the planned Twitter acquisition, and stated that the sale was to avoid an emergency sale of its stock in the event of a forceful Twitter deal.

The news of share disposal comes at a time when Tesla's share price more than halved in 2022, and Musk is facing criticism from Tesla investors over his much greater concentration on Twitter than on Tesla.

In November last year, Musk had sold some of his Tesla shares to pay taxes after asking his Twitter followers their opinion about the proposed sale in a poll.
