Thank you, this is a great article. I noticed a similar distribution for stock returns and similar results when fitting a gaussian distribution. Larger returns (say, 3+ standard deviations away from the mean of approximately 0) were predicted with very low frequencies, while the returns closer to 0 were a good fit to the model. There's money to be made in accurately estimating expected future total returns in the stock market. To understand how to do this for stocks, we have to break total return down into its components.
