One aspect which is potentially tractable even when the events themselves are stochastic is the probability of a of a given size and duration, defined as the area between a time series and a constant threshold.

Retrieved 22 February 2013. 13 Biological flight data can also apparently be mimicked by other models such as composite correlated random walks, which grow across scales to converge on optimal Lévy walks. We show how a particular type of autocorrelation generates power laws consistent with a truncated Lévy flight.

Financial asset prices are unlikely to follow Gaussian distributions.
The market is a Random Walk with a Levy Flight.
This is a Fact and has been statically proven over.
Here is a small example that proves it is a levy flight and not 100 random like some claim(100.
