Mr. Musk, who bought Twitter for $44 billion, sold 19.5 million shares of the electric car company from November 4 to November 8, according to Tuesday’s filings with the Securities and Exchange Commission.
In all, Mr. Musk has sold more than $19 billion worth of Tesla stock since April, including those in Tuesday’s filings, likely to fund his share of the Twitter purchase.
Most of Mr. Musk’s wealth is tied up in shares of Tesla Inc. On Tuesday, his personal net worth dropped below $200 billion, according to Forbes, but he is still the world’s richest person.
Mr. Musk had lined up banks, including Morgan Stanley, to help finance the Twitter deal. His original share of the deal was about $15.5 billion, Wedbush Analyst Dan Ives estimated.
But if equity investors dropped out, Mr. Musk would be on the hook to replace them or throw in more of his own money.
Tesla’s shares closed down $5.78 or 2.9%, at $191.30. The stock has lost 52% of its value since the start of this year.
In comparison, the S and P 500 index has lost about 20% of its value so far this year.
