The full Kelly portfolio strategy's deficiency in the face of estimation errors in practice can be
mitigated by fractional or shrinkage Kelly strategies. This paper provides an alternative, the
RL Kelly strategy, based on a reinforcement learning (RL) framework. RL algorithms are
developed for the practical implementation of the RL Kelly strategy. Extensive simulation
studies are conducted, and the results confirm the superior performance of the RL Kelly
strategies.
