Orso Partners has short position in Affiliated Managers, Bloomberg says

Orso Partners has taken a short position in Affiliated Managers (AMG) Group, the company that backs AQR Capital Management, Loukia Gyftopoulou of Bloomberg reports, citing a letter to the fund’s investors. AQR’s recent growth “is built on regulatory arbitrage that faces immediate scrutiny,” Orso portfolio manager Nathan Koppikar wrote in the letter. Orso contends the most direct way to play the “inevitable fallout” of AQR is by betting against Affiliated Managers, Gyftopoulou points out. Shares of Affiliated are down 1% to $295.77 following Bloomberg’s report.
