Some hedge funds are experiencing very bad days lately, as retail investors bet against their heavy short positions to many well-established U.S. companies. With Gamestop’s meteoric rise still intact, yesterday was American Entertainment Holdings (NYSE: AMC) which caused a headache to many other hedge funds, after a huge jump of 301% in a single trading session. With short interest remains at unsustainable levels all market participants are awaiting for today’s market session.
