The (Mis)Behavior of Markets is a revolutionary reevaluation of the standard tools and models of modern financial theory. Mathematical superstar and inventor of fractal geometry Benoit Mandelbrot joins with science journalist and former Wall Street Journal editor Richard L. Hudson, to reveal what a fractal view of the world of finance looks like. The markets, we learn, are far riskier than we have wanted to believe. From the gyrations of IBM's stock price and the Dow, to cotton trading, and the dollar-Euro exchange rate-Mandelbrot shows that the world of finance can be understood in more accurate, and volatile, terms than the tired theories of yesteryear.
