A report by a news agency that the Securities and Exchange Commission is looking into claims that the electric-vehicle maker failed to properly disclose safety risks associated with its solar panels added to a number of concerns that have tanked the stock's value.
The electric-vehicle maker's stock price has plummeted since it hit an all-time high last month.
The images are from the same company.
The SEC opened an investigation into whether or not SolarCity and the energy company it acquired in 2016 did not publicly disclose a "liability and exposure to property damage, risk of injury", according to a report.
The SEC investigation marks the first time the agency has looked into the SolarCity acquisition, which sparked a years-long shareholder lawsuit.
The SEC's Division of Enforcement confirmed in a letter to the whistle blower in late September that they were still investigating the claims, according to a report.
The company's market value plummeted by more than $250 billion over the same period, after the Monday plunge pushed the stock down more than 20% from a record closing high of $1,229 on November 4.
Representatives for the Securities and Exchange Commission did not respond to Forbes' request.
Musk suggested last month that he would sell about 10% of his stake in the company, sparking concern among investors about how the share prices would hold up. About 5% of the shares Musk owned have been sold.
A group of shareholders took the billionaire to court after they objected to the SolarCity acquisition, which they said was a rescue of a troubled company founded by Musk's cousins. In October, a judge dismissed the direct claims against Musk, but gave shareholders the chance to file a lawsuit in the future.
The number is big.
A total of $977 billion. On Monday, the market value of the company was down from a record $1.2 trillion in early November. Despite crashing since then, shares are still up over the past year, compared to the S&P 500.
Surprising fact.
Musk became the first person to be worth more than $300 billion last month, but he is now worth about $259 billion. Jeff Bezos, the world's second-richest person, is worth $197 billion.
The SEC is investigating claims of solar panel defects.
After taking a break, Musk is back to selling stock.
The dispute was tied to Musk's statements.
This year, the stock of the electric car maker has lost $140 billion in one day.
