High-dimensional multi-period portfolio allocation using deep reinforcement learning

International Review of Economics & Finance2025-02-27Paper
Executive summary

This paper proposes a deep reinforcement learning framework combining CNN and WaveNet for high-dimensional multi-period portfolio allocation and risk management.

What it examines

Researchers propose a novel multi-period portfolio optimization strategy using deep reinforcement learning. The method employs CNNs to capture dynamic price patterns and WaveNet to model asset dependencies, integrated within a Markov decision process framework with a multi-period Bellman equation. It addresses traditional limitations and adapts to high-dimensional market data effectively.

What it concludes

The study shows that using deep reinforcement learning to choose investments over several periods can make better decisions in complex financial markets by handling risks and costs. It may be used for dynamic asset allocation and algorithmic trading. Future research could refine the model and test it in different markets.
