George Soros

George Soros (born 1930, Budapest) is a macro investor and founder of Soros Fund Management, best known for the 1992 trade that broke the Bank of England by shorting the British pound (GBP) for a reported $1B profit. He introduced the concept of reflexivity to financial theory in The Alchemy of Finance (1987), arguing that participant expectations in markets do not merely reflect reality but actively shape it — creating feedback loops that can sustain prices far from any intrinsic value before collapsing sharply.

His reflexivity framework distinguishes him from efficient-market theorists: Soros argued that markets are not self-correcting machines but unstable systems where belief and price reinforce each other. This makes large trend trades possible (riding the self-reinforcing loop) and also creates sharp reversals (when the loop breaks or reverses).

Beyond theory, Soros is known for concentrated macro bets based on narrative and capital flow analysis — not company fundamentals. He cited his own fallibility as a feature of his method: "I'm only rich because I know when I'm wrong."

GCR cited Soros as a primary intellectual influence, explicitly connecting Soros's reflexivity and contrarianism to his own "Tree of Life" trading philosophy.
