Overview

Computational study demonstrates superior risk-adjusted portfolio performance in multi-asset allocation, indicating the utility of embedding dual-regime signals into reinforcement learning.

Key Points

To develop and evaluate a hybrid regime-aware reinforcement learning framework using a mixture-of-experts architecture for multi-period dynamic asset allocation.
Constructed a mixture-of-experts architecture assigning distinct Bull and Bear agents optimized via Recurrent Proximal Policy Optimization (PPO) with LSTM-based actor-critic networks.
Integrated dual-regime forecasts into state representations, enforced action masking on regime-dependent asset sets, and trained policies using an offline-sim-to-online-deployment pipeline combining synthetic and historical data.
Backtested the multi-asset portfolio allocation framework over historical financial data from 1990 to 2025 against static-weight regime-switching benchmarks.
The proposed regime-aware framework outperformed static-weight regime-switching benchmark models over the 1990–2025 evaluation period.
Agents learned adaptive portfolio tilts dynamically shifting weight toward recent top-performing assets within each identified market regime.
