Daniel Kahneman, et al.
Summary via publisher (Little, Brown Spark)
In Noise, Daniel Kahneman, Olivier Sibony, and Cass R.

Consequently, at horizons greater than five years, returns –individual or portfolio– will be positively skewed under reasonable parametrizations. From an investor perspective, the strong positive skewness implies that the mean compound return will serve as a poor guide for typical long-horizon outcomes. Moreover, the large effects of compounding on higher-order moments are shown to affect the validity of Taylor expansions used to approximate preferences for skewness, when applied to returns of annual or longer horizons.
