Detroit, April 29: Elon Musk has sold 4.4 million shares of Tesla stock worth roughly $4 billion, most likely to help fund his purchase of Twitter.

Musk reported the sale in a filing with the Securities and Exchange Commission on Thursday. The shares were sold over the past few days, at prices ranging from $872.02 to $999.13.

The world's richest man, who is the CEO of Tesla, tweeted that he doesn't plan any further sales of the company's shares. Most of the sales took place on Tuesday, a day when Tesla shares closed down 12%, a huge single-day drop. Tesla CEO Elon Musk Backs Free Speech, Says ‘I Hope That Even My Worst Critics Remain on Twitter’.
