The tweet heard around the capital markets regarding Tesla CEO Elon Musk’s idea of taking the electric auto manufacturer private is now landing him in hot water as the SEC has filed a civil lawsuit against Musk, alleging he issued “false and misleading” statements and failed to communicate material company events to regulators.

Shares of Tesla (TSLA) took a deep dive as the stock plummeted over 12% as of 11:00 a.m. ET, hurting ETFs with heavy weightings, such as the VanEck Vectors Global Alt Energy ETF (NYSEArca: GEX)–down 1.24%, ARK Industrial Innovation ETF (NYSEArca: ARKQ)–down 1.34% and the First Trust NASDAQ Cln Edge GrnEngyETF (NASDAQ: QCLN)–down 1.11%.

Downward pressure on Tesla’s share price was also applied as investors are positing whether the SEC lawsuit could bring about an abrupt departure of Musk on a temporary or permanent basis.

“The SEC civil action may lead to Musk’s exit from Tesla (either permanently or temporarily) and the Musk premium in the shares dissipating,” analyst Brian Johnson said in a note. “Tesla shares have ~$130 of Musk premium for future success that might dissipate.”

Musk’s Mercurial Behavior

The SEC lawsuit is just the latest installment of Musk’s mercurial behavior as of late, causing top executives to head for the exits earlier this month after Musk smoked marijuana on the podcast “The Joe Rogan Experience.” Musk’s behavior on the podcast is a culmination of what has been tumultuous times for the electric carmaker founder, which started when he first sent a tweet that he was considering taking the company private at a price of $420 a share, citing that it was “the best path forward.”

The decision to privatize Tesla halted trading of the company’s shares for 92 minutes, leaving Tesla investors in a panic. Not long thereafter, Musk reneged on the decision after reports surfaced that a Saudi Arabian sovereign wealth fund and tech giant Apple were potential suitors to purchase Tesla. Aside form Musk’s mercurial behavior as of late, the electric carmaker continues to burn cash as it struggles to secure alternate sources of funding.

“We see the potential for negative sentiment to impact demand and employee morale,” Morgan Stanley analyst Adam Jonas said in an investor note. “In our view, this is particularly a risk if the situation is not resolved relatively quickly.”
