We argue that the natural candidate for such statistics is the investment horizons distribution. This distribution of waiting times needed to achieve a predefined level of return is obtained from (often detrended) historic asset prices. Such a distribution typically goes through a maximum at a time called the {\em optimal investment horizon}, $τ^*_ρ$, since this defines the most likely waiting time for obtaining a given return $ρ$. By considering equal positive and negative levels of return, we report on a quantitative gain-loss asymmetry most pronounced for short horizons. It is argued that this asymmetry reflects the market dynamics and we speculate over the origin of this asymmetry.Latex, 6 pages, 3 figuresSoft Condensed MatterStatistical MechanicsStatistical Financetext
