Key Takeaways:
A short-selling firm is targeting Affiliated Managers Group, a multi-billion dollar asset manager, arguing that the core profit engine of its star subsidiary, AQR Capital Management, is built on tax strategies that are facing an imminent regulatory crackdown.
"This aggressive tax positioning is built on regulatory arbitrage and is highly vulnerable to IRS scrutiny," Orso Partners’ portfolio manager Nathan Koppikar said in a letter to investors obtained by Bloomberg.
The report erased a 2.9% intraday rally in AMG’s stock, pushing it down 1.7% to $294.28. The core of Orso’s thesis is AQR's tax-aware long-short strategies, which have grown tenfold in two years to account for approximately $57 billion in assets. These products, part of a $1 trillion market, help wealthy investors defer taxes by holding winners while selling losers to harvest tax losses.
Orso argues that a regulatory hammer is about to fall. With AQR expected to contribute over 20 percent of AMG's entire earnings by 2026, any disruption to this strategy could significantly impact the parent company's bottom line. AMG reported net inflows of $51 billion last year, a 36 percent increase that it attributed "primarily driven by AQR."
The strategy in question, known as tax-loss harvesting, has become a popular product for high-net-worth individuals, offered through various vehicles like hedge funds, ETFs, and separately managed accounts. The basic principle involves offsetting taxable gains with realized losses.
However, Orso’s letter alleges that AQR uses leverage and complex derivatives to generate large trading losses, a practice that may draw unwanted attention from the U.S. Internal Revenue Service. "When the regulatory hammer falls, AQR's assets under management and fee revenues will be hit hard," Koppikar wrote.
The threat is not merely theoretical. The U.S. Treasury Department is reportedly preparing to tighten regulations on at least one category of these tax-deferral strategies. In a move seen as a precursor to broader industry constraints, Fidelity Investments began restricting new multi-leg separately managed accounts in February.
For AMG, the concentration risk is clear. The firm's Chief Financial Officer, Dava Ritchea, highlighted AQR's "strong performance, continued innovation, and differentiated expertise" in a February call. That same engine of growth is now the focal point of a targeted short campaign, presenting a direct threat to AMG's future profitability.
