InvestPhilBench: A Multi-Layer Dynamic Benchmark for Evaluating Large Language Model Procedural Reasoning in Expert Investment Philosophy
Researchers introduce InvestPhilBench, a comprehensive benchmark for testing large language models' ability to reconstruct and apply expert investment decision frameworks. The v0.6 release reveals that while state-of-the-art models achieve high composite scores (0.932), they exhibit significant procedural reasoning deficits (GRA scores of 0.57-0.77), indicating that fluent prose masks deeper gaps in step-by-step investment logic.
