TY - JOUR T1 - Dynamic Replication and Hedging: <em>A Reinforcement Learning Approach</em> JF - The Journal of Financial Data Science SP - 159 LP - 171 DO - 10.3905/jfds.2019.1.1.159 VL - 1 IS - 1 AU - Petter N.

Based on reinforcement learning (RL), a well-established machine learning technique, the authors propose a model that is flexible, accurate and very promising for real-world applications. A key strength of the RL approach is that it does not make any assumptions about the form of trading cost. RL learns the minimum variance hedge subject to whatever transaction cost function one provides. All that it needs is a good simulator, in which transaction costs and options prices are simulated accurately.TOPICS: Options, big data/machine learning, portfolio management/multi-asset allocation ER -
