This Week’s Book: The Fund of Funds King, Bernie Cornfeld

In May, I read A Short History of Financial Euphoria, which described famous financial bubbles from the 1600s’ tulip mania to the 1980s’ junk-bond frenzy and savings-and-loan crisis. One of the companies mentioned was Investors Overseas Services (IOS), a multibillion-dollar fund of funds built in the 1960s by Bernie Cornfeld. I’ve read about IOS and Cornfeld in other books and was always curious, so I read a biography about Cornfeld, The Bernie Cornfeld Story, written by an early IOS employee.

The biography provides an insider’s perspective on Cornfeld’s life, his personality, and how he built IOS. It details what allowed Cornfeld to rise from social worker in the United States to international financier in Switzerland, as well as his battles with the SEC and how his empire crumbled after IOS’s IPO in 1969.

Cornfeld’s story was pretty wild. It’s interesting to learn how he and IOS rode the bull market of the 1950s and 1960s to insane heights but then were crushed when the market began to reverse in the early 1970s.

I still want to learn more about Cornfeld and will look for more books on him and his associates.

The Bernie Cornfeld Story

July 2025

Biography chronicling the dramatic rise and fall of Bernard “Bernie” Cornfeld, who built Investors Overseas Services (IOS) into a multibillion-dollar offshore fund-of-funds empire in the 1960s. Traces his path from immigrant social worker in the U.S. to flamboyant financier in Switzerland, pioneering aggressive sales and marketing tactics, which led to rapid international growth. The book reveals deep structural flaws in IOS that ultimately led to a spectacular collapse.
A Short History of Financial Euphoria by John Kenneth Galbraith mentioned IOS and Cornfeld—that led me to this book. Inside look at how one of the first and biggest fund-of-funds worked. IOS blew up after interest rates rose, macro conditions shifted, and the business was mismanaged. Read 1970 hardcover.
