MetaPS: Adaptive Strategy Selection for Financial Markets Using Simulated Supervision

The article analyzes MetaPS, a simulation‑guided framework that adaptively selects executable trading programs from a strategy library, showing that supervised meta‑strategy learning improves returns across 0.8B‑9B parameter models and outperforms fixed‑strategy baselines, direct decision agents, and prompt‑based LLM agents in both stock and sandbox environments.

AI‑Trader: Real‑time Benchmark for Autonomous LLM Agents in Financial Markets

The AI‑Trader benchmark evaluates large language model agents in fully autonomous, real‑time US stock, Chinese A‑share, and cryptocurrency markets, revealing that general intelligence alone does not guarantee profitable trading, while robust risk‑control mechanisms drive cross‑market stability and excess returns.

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.
