Deep Reinforcement Learning for Option Replication and Hedging, from the Fall 2020 issue of The Journal of Financial Data Science, takes a “deep” dive into reinforcement learning approaches for option portfolios. It explores ways of training a computer “agent” by a clever form of trial and error to learn to replicate and hedge an option portfolio directly from data. It’s a positive step forward in the use of modern mathematical approaches to portfolio hedging, and the authors are extending their research in deep reinforcement learning (DRL) to real-world problems in finance, including trading, portfolio management, and hedging.TOPICS: Big data/machine learning, options, risk management, simulations
