Investor background
William von Mueffling
“The successful buyers of growth…focus on the strength of the franchise.”Bruce Greenwald, identifying Warren Buffett and William von Mueffling as examples
William von Mueffling is the president and chief investment officer of Cantillon Capital Management, a global equity investment firm he founded in 2003. He began his career researching European companies at Deutsche Bank before earning an MBA from Columbia Business School in 1995. Bruce Greenwald’s value-investing course helped him combine business-cycle analysis with the principles of intrinsic value and margin of safety.
Von Mueffling first became prominent at Lazard Asset Management, where he managed hedge funds and established an exceptional record during the technology bubble. Institutional Investor reported that the Lazard European Opportunities Fund returned an annualized 58% between August 1998 and December 2002. When he left Lazard, much of his team and nearly $3 billion of client capital followed him to Cantillon.
His present philosophy, however, was shaped partly by failure. After losses and costly short covering during the 2009 market rebound, he closed Cantillon’s long-short funds, returned approximately $3.5 billion and concentrated the firm on long-only investing.
Cantillon seeks what von Mueffling calls “financial productivity at a discount”: businesses capable of sustaining high returns on capital because they possess genuine competitive advantages. The firm studies networks, brands, distribution systems, scarce physical assets and other barriers to replication. It also examines whether management can reinvest or distribute the resulting cash without destroying shareholder value. High historical ROE alone is insufficient; the economic reason for that ROE must be durable.
Von Mueffling is worth following because he combines a documented early record, more than three decades of global company research and an unusually coherent quality-value framework. Unlike highly concentrated investors, Cantillon generally owns a broader collection of exceptional businesses. Its focus lies less in making a few dramatic bets than in repeatedly purchasing sustainable financial productivity below intrinsic value.
