How DeepAries’s Adaptive Rebalancing Timing Boosts Portfolio Returns

DeepAries is a novel deep reinforcement‑learning framework that jointly learns when to rebalance a portfolio and how to allocate assets by combining a Transformer‑based state encoder with PPO, and extensive experiments on four major markets show it significantly outperforms fixed‑frequency baselines in risk‑adjusted return, transaction cost, and drawdown.
