A federal jury in Los Angeles has convicted Andrew Left, the 55-year-old founder of Citron Research, on one count of securities fraud scheme and 12 counts of securities fraud, finding him guilty of manipulating stock prices to generate at least $21 million in illicit profits over several years. The verdict, delivered after a 15-day trial, marks one of the most significant market-manipulation convictions targeting a prominent financial commentator in recent US history.

How the Scheme Worked

According to trial evidence, Left exploited Citron Research's market-moving reputation by quietly building long or short positions — often through short-dated options contracts — in targeted companies before publishing investment commentary. Once his reports triggered price movements, he would close those positions within hours, at prices that frequently diverged sharply from the longer-term targets he had publicly promoted to investors.

Prosecutors argued that Left used his regular appearances on major business television networks to project credibility while concealing his true trading intentions. The government said he was, in effect, taking positions opposite to the guidance he was publicly dispensing.

The Nvidia Trade That Featured at Trial

One of the most striking examples presented to the jury involved chipmaker Nvidia in November 2018. Prosecutors alleged that Left encouraged a portfolio manager to develop a bullish thesis on the stock, accumulated his own positions, and then posted publicly on Citron's social media account: 'Citron buys $NVDA. This is the first time in 2 years stock offers an appealing risk-reward to investors . . . We see $165 before we see $120.' Despite that public projection, he reportedly sold his positions less than two hours later, earning more than $960,000 in profit, according to prosecutors.

What Federal Authorities Said

Bill Essayli, First Assistant United States Attorney, said Left used television appearances to disguise his intentions and manipulate the market. 'Left used his TV appearances to disguise his intentions, manipulate the stock market, and pad his pockets,' Essayli said. 'A fair and transparent securities market is a foundation of our nation's financial system. We will continue to bring to justice individuals who abuse the public trust placed in financial advisors.'

Patrick Grandy, Assistant Director in Charge of the FBI's Los Angeles Field Office, warned that such frauds erode investor confidence. 'While this conviction cannot make up for the significant and emotional harm he inflicted upon his unwitting investors, it does send a message to those who may be looking to profit from similar schemes — think twice,' Grandy said.

Verdict, Acquittals, and Sentencing

The jury acquitted Left on four securities fraud counts related to trades involving four specific companies. He is scheduled to be sentenced on 31 August before US District Judge Virginia A. Phillips. Prosecutors said he faces a statutory maximum of 25 years in federal prison on the securities fraud scheme count and up to 20 years on each individual securities fraud count.

Citron Research's Rise and Fall

Citron Research spent roughly two decades as one of Wall Street's best-known activist research firms, regularly publishing reports that challenged the valuations of publicly traded companies. Left cultivated a large following among both retail and institutional investors through frequent financial television appearances. The conviction now casts a long shadow over that legacy and raises broader questions about the accountability of market commentators who hold significant sway over retail investors.
