Dirichlet policies for reinforced factor portfolios

Eric André, Guillaume Coqueret·2021

Factor investing in equities, studied by André and Coqueret in 2021 with reinforcement learning. The abstract mentions a benchmark but not an out-of-sample test, transaction costs, multiple testing or the size of the universe.

“Across a large range of parametric choices, our result indicates that RL-based portfolios are very close to the equally-weighted (1/N) allocation.”
