Adaptive Markets
Andrew W. Lo’s *Adaptive Markets* upends decades of financial orthodoxy by replacing the rigid Efficient Market Hypothesis with a dynamic framework rooted in evolution and neuroscience. Lo argues that financial markets aren’t governed by perfectly rational “economic men” but by humans shaped by millions of years of survival instincts—instructions that often misfire in the fast-paced, modern financial landscape. Drawing on real-world examples, from a pilot’s life-saving fear response to the 2008 financial crisis and 2007 quant crash, he explains how market efficiency shifts as investors adapt to changing environments. The book also explores how evolutionary logic applies to hedge fund evolution, regulatory design, and even using financial tools to solve global challenges like cancer research and climate change. By bridging biology, neuroscience, and finance, Lo offers a compelling new lens to decode market chaos, identify opportunities, and reimagine finance’s role in advancing human well-being.
