The Misbehavior of Markets
Rough markets can defeat smooth assumptions.
Big Idea
The authors argue that financial markets are rougher and more prone to extreme moves than many conventional risk models assume.
Large Moves Matter
Extreme changes can occur more often than a bell-shaped model leads users to expect.
Volatility Clusters
Turbulent periods can arrive together instead of being evenly scattered across time.
Fractal Roughness
The book explores patterns that look irregular at several scales of observation.
Market Time
Trading activity changes pace, so equal amounts of clock time need not contain equal amounts of market action.
Models Have Boundaries
Fractal models offer another approach to risk, not an exact way to forecast the next price.
Khizooo Take
Check how a model treats extreme events and quiet versus turbulent periods before relying on its risk estimate.

Remember
A neat model can underestimate a rough world.
