🤖AlphaMemo is a new LLM-based agent framework that improves automated financial factor discovery by using structured memory of past search patterns rather than naive trajectory replay. The system records reusable evidence about which code modifications succeed or fail in specific contexts, demonstrating better out-of-sample performance on major indices while reducing redundant exploration.

🧠Researchers benchmark a retrieval-augmented LLM system for equity factor ranking using strictly decision-time information, avoiding data leakage common in forecasting benchmarks. The 7B model achieves modest positive results (median IC +0.154) comparable to simpler kNN baselines, suggesting real-time macro data and historical analogies drive most signal while LLMs may add marginal value in extreme rankings.

🧠Researchers introduce AlphaForgeBench, a new evaluation framework that addresses critical instability issues in Large Language Models deployed as trading agents. Rather than having LLMs generate discrete trading actions, the framework redefines their role as quantitative researchers producing alpha factors and strategies, enabling deterministic, reproducible evaluation aligned with real-world financial workflows.

🧠Researchers developed a new portfolio reinforcement learning method called macro-conditioned scenario-context rollout (SCR) that addresses market regime shifts and distribution changes. The approach generates plausible return scenarios under stress events and improves portfolio performance by up to 76% in Sharpe ratio and reduces maximum drawdown by 53%.
