Short seller Andrew Left is set to face a jury trial over allegations of market manipulation, according to court proceedings.

Left, a well-known figure in activist short selling, has been charged with securities violations related to his trading activities and public statements about targeted companies.

The case represents one of the most high-profile prosecutions of a short seller in recent years, as regulators have increased scrutiny of activist investors who publicly bet against companies.

Short sellers like Left typically research companies they believe are overvalued, take short positions, and then publish reports detailing their concerns to the public.

The trial will examine whether Left's actions crossed legal boundaries in his efforts to profit from declining stock prices of companies he targeted.
