Tesla boss Elon Musk wiped $14bn (£11bn) off the carmaker's value after tweeting its share price was too high.

It also knocked $3bn off Mr Musk's own stake in Tesla as investors promptly bailed out of the company.

"Tesla stock price too high imo," he said in one of several tweets that included a vow to sell his possessions.

In other tweets, he said his girlfriend was mad at him, while another simply read: "Rage, rage against the dying of the light of consciousness."

In 2018, a tweet about Tesla's future on the New York stock market led to regulators fining the company $20m and Mr Musk agreeing to have all further posts on the platform pre-screened by lawyers.

'Headache'

On Friday, the Wall Street Journal reported it had asked the billionaire if he was joking about the share price tweet and whether it had been vetted, receiving the reply "No".

Tesla's share price has surged this year, putting the electric carmaker's value at close to $100bn, a mark that would trigger a bonus payment of hundreds of millions of dollars to the entrepreneur.

"We view these Musk comments as tongue in cheek and it's Elon being Elon. It's certainly a headache for investors for him to venture into this area as his tweeting remains a hot button issue and [Wall] Street clearly is frustrated," Wedbush Securities analyst Daniel Ives told Reuters news agency.

In 2018, Mr Musk tweeted that he may have secured funding to possibly remove Tesla from the stock market and take it private, which again led to swings in the share price. The Securities and Exchange Commission judged it a market-moving comment, fined him and forced Tesla to put in place checks to ensure it did not happen again.

But last month, a federal judge said Tesla and Musk must face a lawsuit by shareholders over the going-private tweet, including a claim that Mr Musk intended to defraud them.

Earlier this week he tweeted to his 33.4 million followers some strong criticism of US stay-at-home restrictions because of the coronavirus pandemic. Last year he found himself in court after tweeting that a British diver was a "pedo guy".

Mr Musk said the promise to sell his possessions included his house, formerly owned by actor and producer Gene Wilder, and bought in 2013.

"One stipulation on sale," he tweeted, "I own Gene Wilder's old house. It cannot be torn down or lose any of its soul."
