More Money Than God, in detail
Sebastian Mallaby's history of hedge funds begins with Alfred Winslow Jones, who in 1949 invented the basic structure that still defines the industry: borrow money to buy what you think will go up, sell short what you think will go down, take a 20 percent cut of the profits. The book traces the industry from that origin through George Soros breaking the Bank of England in 1992, through Julian Robertson's Tiger Management, through the Long-Term Capital Management collapse of 1998, to the crisis of 2008 and beyond.
The central argument is counterintuitive. Mallaby's contention is that hedge funds — despite their opacity, their fees, and their occasional spectacular blowups — have generally been a stabilizing force in financial markets, not a destabilizing one. They make markets more efficient by trading against mispricing. They tend to be short when markets are euphoric and long when everyone else has fled. The firms that survived across decades did so by being right about things that consensus opinion had wrong, not by riding leverage into a bubble.
The book is strongest as character study. Soros is drawn with real complexity — intellectually brilliant, philosophically serious, and willing to take positions of such size that they could move the markets he was betting on. Robertson ran Tiger with the obsessiveness of a sports coach. Paul Tudor Jones and Michael Steinhardt get full chapters. Mallaby interviewed most of the major figures, which gives the narrative an intimacy that financial histories often lack. The LTCM chapter, covering a $125 billion collapse driven by Nobel laureates who had solved risk mathematically and then met an event outside their model, is particularly good.
The book has limits. It was completed before the full implications of algorithmic and high-frequency trading became clear, and some of its conclusions about hedge fund stability look different in light of developments since 2010. But as a historical account of how the industry evolved, who built it, and what the operating philosophy of the best practitioners actually was, it remains the definitive single volume.
The big ideas
- 1.
Alfred Winslow Jones invented the hedge fund structure in 1949 — leveraged long positions offset by short sales, plus a performance fee — and most of what followed is variation on that original design.
- 2.
The best hedge funds make markets more efficient by taking the other side of crowd behavior. They buy when everyone is selling and short when everyone is buying, which tends toward stability rather than instability.
- 3.
George Soros's reflexivity theory holds that market prices influence the fundamentals they are supposed to reflect — creating feedback loops that standard efficient-market models ignore.
