Andrew Left, the high-profile short-seller and founder of Citron Research, is set to stand trial in May for alleged securities fraud and stock price manipulation. Left, who rose to fame by correctly calling several notorious stock market frauds, denies the charges and says he's confident he will prevail, though he admits to feeling nervous as the trial approaches.

Why it matters

Left's case highlights the ongoing tensions between short-sellers, who aim to profit from falling stock prices, and regulators who are cracking down on alleged market manipulation. The outcome could have broader implications for how short-sellers are able to operate and share their views on social media.

The details

Left was indicted in July 2024 on charges that he manipulated the prices of over 20 stocks, including Tesla, Nvidia, and Meta Platforms. He is accused of providing false and misleading information, including tweeting bullish commentary that pushed prices up, and then selling shortly after. The feds also allege that he maintained undisclosed relationships with hedge funds.

  • Left found out he was under investigation in January 2021 when FBI agents visited his home.
  • Left was indicted in July 2024.
  • The trial is scheduled to begin in May 2026.
