Nate Anderson, founder of Hindenburg Research, a prominent US short-selling firm, said in a statement that he had decided to disband the research group. "Nearly 100 people, including billionaires and oligarchs, have been subject to civil or criminal prosecution by regulators at least in part because of our work," he wrote. "We have shaken up some empires that we believe need to be shaken up." "Right now, I will focus on making sure everyone on our team can achieve what they want next."
