Abstract: | Portfolio Selection (PS) is a perennial financial engineering problem that requires determining a strategy for dynamically allocating wealth among a set of portfolio assets to maximise the long-term return. We investigate state-of-the-art Deep Reinforcement Learning (DRL) algorithms that have proven to be ideal for continuous action spaces, mainly Deep Deterministic Policy Gradient (DDPG) and Twin Delayed Deep Deterministic Policy Gradient (TD3), for the PS problem. Furthermore, we investigate the effect of including stock movement prediction indicators in the state representation, and the potential of using an ensemble framework that combines multiple DRL models. Our experiments show that TD3-based models generally perform better than DDPG-based ones when used on real stock trading data. Furthermore, the introduction of additional financial indicators in the state representation was found to have a positive effect over all. Lastly, an ensemble model also showed promising results, consistently beating the baselines used, albeit not all other DRL models. |
