Andrew Left Convicted in LA for Securities Fraud

A federal jury in Los Angeles convicted Andrew Left, founder of Citron Research, on multiple securities fraud counts for using public market commentary and social media posts to influence stock prices while trading the affected securities.

The three-week trial ended with jurors finding Left guilty on the central securities fraud count and on several additional counts tied to specific securities; he was acquitted on other charges.

Prosecutors told the jury that Left used public statements to shape investor sentiment and then quickly closed positions, generating more than $20 million in profits from 2018 through 2023. The case began with an indictment filed in 2024.

Evidence introduced at trial included private messages prosecutors said contradicted Left’s public commentary, messages suggesting coordination with hedge funds, and exchanges in which Left discussed the reach of his research and his social media influence on retail investors.

Left criticized the verdict and indicated he will appeal. In a written statement he wrote, “My market commentary reflected genuinely held opinions,” adding he believed there was nothing improper in profiting from market moves that followed publication of his analysis.

Left remains free pending sentencing, which is scheduled for August.

Legal and market observers said the verdict could affect how short sellers document research, disclose positions and communicate with other market participants. Some firms adjusted disclosures and compliance procedures after the 2024 indictment.

Sentencing will determine any fines and trading restrictions, and Left’s planned appeal will proceed through the federal courts.
