Portfolio Management with Amazon SageMaker RL

Portfolio management is the process of constant redistribution of a capital into a set of different financial assets. Given the historic prices of a list of stocks and current portfolio allocation, the goal is to maximize the return while restraining the risk. In this demo, we use a reinforcement learning solution framework to manage the portfolio by continuously reallocating several stocks. Based on the setup in [1], we use a tensor input constructed from historical price data, then apply an actor-critic policy gradient algorithm to accommodate the continuous actions (reallocations). The customized environment is constructed using Open AI gym, and the RL agents are trained using AWS SageMaker.
