Practical Deep Reinforcement Learning Approach for Stock Trading
Practical Deep Reinforcement Learning Approach for Stock Trading
This paper investigates the application of deep reinforcement learning (DRL) to develop optimal stock trading strategies in complex and dynamic financial markets. The authors address the challenge of strategy optimization by training a DRL agent using daily price data from 30 selected stocks, which serves as the trading environment. The methodology involves leveraging DRL techniques to enable the agent to learn adaptive trading decisions aimed at maximizing investment returns.
The study evaluates the performance of the DRL-based strategy by comparing it with two benchmarks: the Dow Jones Industrial Average and a traditional min-variance portfolio allocation strategy. Results indicate that the proposed approach outperforms both baselines in terms of Sharpe ratio and cumulative returns, demonstrating its potential for enhancing profitability and risk-adjusted performance in stock trading. This work contributes to quantitative finance by showcasing DRL's capability to handle market uncertainties and optimize trading decisions effectively.
