Researchers have developed a novel three-phase foundation model for personalized portfolio management using deep reinforcement learning. This system addresses limitations in prior work by avoiding ticker lock-in, employing monolithic objectives, and using static user models. The model integrates a time series foundation model, Chronos, and a Mixture of Experts architecture to simultaneously pursue multiple investment goals, including tax-loss harvesting. Personalization is achieved through a lightweight LoRA module fine-tuned on individual transaction history, inferring objectives from trading behavior. AI
