A high-profile research analyst who identifies and bets on troubled companies has acquired an unusual and perhaps unwarranted amount of influence in the brief period of time he’s been in this line of work. Forty-six-year-old Fraser Perring, a resident of Lincoln, England, founded and runs Viceroy Research with two other analysts. Their investigations of what they claim are misleading corporate disclosures or flawed business models have regularly sent the stock prices of their targets spiraling downward. Perring is a short seller who appears to relish the attention that comes from being publicly bearish on companies in a marketplace that seems largely designed to push stock prices higher. And with no client funds to manage (Perring trades only for his own account) and thus few regulatory disclosures to make, he is free to discuss his globe-trotting lifestyle with a reporter or use his Twitter account to launch broadsides against anything that irks him.
