Beating mean-variance with stochastic dominance!
Mean-variance with stochastic dominance may sound like a foreign language to most, but for traders modelling and algorithms are central to helping gain an edge over their counterparts.
Today, mean-variance models are the preferred risk models as they are easy to understand and convenient from a computational point of view. However, they mainly only use two statistics to characterise the portfolio return distribution and thus, may ignore important information.
A more general approach is stochastic dominance, which considers the entire distribution of a random variable and relies on expected utility theory. It assumes risk-averse investors maximising expected utility without the drawback of defining a specific utility function. So, it is appealing to a wide group of investors.
Second-order stochastic dominance particularly is broadly accepted as important principle in portfolio optimisation. Its approach, even though being computationally intensive, ensures that the cumulative portfolio return exceeds the return of a given benchmark.
It can reduce downside risk on one side, and increase upside potential on the other side. And isn’t that what traders are looking for? Beating mean-variance with stochastic dominance!
