A federal jury in Los Angeles convicted Andrew Left of securities fraud on Monday. Prosecutors proved that the 55-year-old trader used his reputation as a stock expert to manipulate share prices for personal gain. He typically issued bold public calls on social media to incite price moves before exiting his positions shortly after.

Justice Department lawyers argued that Left targeted small companies to create quick profits, rather than conducting genuine research. This conviction marks a major win for regulators investigating whether aggressive short sellers distort markets through misleading campaigns. Left testified in his own defense, claiming his stock theories were authentic and his actions were simply those of an active trader.

Left now faces a maximum 25-year prison term for the lead charge. He plans to appeal the verdict, insisting the jury reached the wrong conclusion. Sentencing is scheduled for August 31, marking a legal defeat for a man who built a career betting against corporate stability through public accusations of fraud.
