Do You Trust Bill Ackman to Build a $250 Billion Fund Manager?

Celebrity fund manager and activist investor Bill Ackman just sold 10% of his investment management company in a deal that valued Pershing Square at $10.5 billion. An initial public offering could come as soon as next year, the Wall Street Journal has reported.

The valuation amounts to about 64% of the $16.3 billion in assets Pershing Square is said to manage. That compares with market capitalizations of 15% to 18% of assets under management for the four public hedge-fund-style managers valued by the market at more than $10 billion: Blackstone Inc., KKR & Co., Ares Management Corp. and Blue Owl Capital Inc. Traditional public asset management companies such as BlackRock Inc., Bank of New York Mellon Corp., Ameriprise Financial Inc., T. Rowe Price Group Inc., Northern Trust Corp. and Franklin Resources Inc. have ratios from under 1% to about 4%.

Before thinking about how Ackman talked some deep pockets into that valuation, let’s consider the Finance 101 theory of asset manager valuation. We teach two simple theories to aspiring financial professionals — that managers should sell for 0% of AUM and 100% of AUM.

Before you snort in disgust at ivory-tower academics, consider the story of French entomologist Antoine Magnan, who wrote in 1934, “I applied the laws of air resistance to insects, and I arrived with Mr. St Lague at the conclusion that their flight is impossible.” This entered into popular culture as the claim that scientists think bumblebees can’t fly. But Magnan was actually calling attention to deficiencies in the understanding of aerodynamics. Modern finance professors use the simple theories to force students to think about the asset management business.

The 0% valuation is based on the legal theory that asset managers have a fiduciary duty to act in the best interests of their investors. This is why John Bogle, the founder of Vanguard Group Inc. and the most fair-minded person I ever knew, gave ownership of the company to its fund investors. Any excess value of the business, above salaries and expenses, belonged to investors, not managers. Although he benefited individual investors more than any other person in history, he died with a reported $80 million net worth — comfortably wealthy, of course, but Citadel Securities’ Ken Griffin earned as much every week in 2022.
