Why Tesla Stock Got Clobbered Today

Shares of Tesla (NASDAQ: TSLA) ran into a ditch Monday morning, sliding 4.8% as of 10 a.m. EDT on twin negative news items from Reuters and The New York Times. Remember how last week, Tesla stock got a brief pop, and investors had a chuckle, over news that Tesla was selling a limited edition "Cyberwhistle" shaped like its long-awaited (and still not here) Cybertruck? Turns out, a whistleblower within Tesla's solar systems division (the artist formerly known as SolarCity) is alleging to the Securities and Exchange Commission that the company "failed to properly notify its shareholders and the public of fire risks associated with solar panel system defects over several years," reports Reuters.
