A fat tailed probability distribution is one in which extreme events are more probable.
For example the normal distribution is typically a very good fit over a wide range of the
most likely outcomes in finance. However, it is generally accepted that extreme events
such as crashes are more probable it suggests.
This means that a model based on the normal distribution will give good estimates over
a reasonable range, but still under-estimate extremes. For example a model might accurately
estimate the chance of a share price falling 10%, but greatly under-estimate the chance of
the market falling 50%.
