Query: For the financial theorist in you

Mandelbrot is, of course, a genius. In this book Mandelbot attacks orthodox financial theory and substitutes a fractal view of how markets everywhere behave. It's all interesting and Mandelbrot writes in a very accessible style. The conclusions he draws are non-controversial (markets are turbulent, markets are far riskier than we think, etc). An alternative to evaluating risk and reward is offered and might be of interest to theoretical finance people and perhaps some people who trade as a hobby or for a living and like to ponder ways to avoid severe financial loss or ruin. Having known a few traders in complex financial derivatives who did experience ruin, the topic is of great interest to me. As a long term investor who relies mainly on index stock and bond funds and real estate for my investments, I'm happy to see Dr. Mandelbrot's wild graphs in a book and not on my financial statements (fingers crossed!).
