Soros's Reflexivity — How Markets Shape the Reality They Reflect

Standard financial theory assumes markets reflect reality. Soros observed the opposite: markets also create reality. This insight — reflexivity — explains why bubbles are not just mispricing errors but self-reinforcing processes that fundamentally alter the underlying businesses and economies they appear to reflect.

Why This Matters

George Soros's theory of reflexivity, developed over decades of macro investing and articulated in The Alchemy of Finance, challenges the assumption that stock prices passively reflect underlying fundamentals. His observation: the relationship between price and fundamentals runs in both directions. Prices do reflect fundamentals (the standard view), but fundamentals are also shaped by prices. A rising stock price allows a company to raise cheap equity capital, makes acquisitions easier, attracts talent, and enhances the company's ability to negotiate with customers and suppliers — all of which improve the fundamentals that supposedly justified the price rise. This two-way feedback loop creates self-reinforcing processes that overshoot far beyond what passive reflection of fundamentals would produce.
