Can AI Do Financial Research? LLM-Guided Hypothesis Discovery in Asset Pricing
Researchers have shown that large language models (LLMs), a type of artificial intelligence, can autonomously generate and test asset pricing hypotheses. In a transparent system using a symbolic accounting language, the AI proposed 280 investment signals. Of these, 38 showed unique predictive power even after comparison with 209 known financial anomalies. The study highlights AI’s potential to accelerate financial discovery while noting current limits, such as reliance on initial design and the scope of the accounting language.
What it examines
This paper explores if an AI agent, using a large language model, can independently discover and test new ideas in asset pricing. The AI works within a human-designed system, using accounting formulas and automated tests, to find and evaluate financial signals that predict stock returns.
What it concludes
The study shows that AI can help find new, meaningful financial signals, some of which are not explained by existing models. This approach could speed up financial research, improve investment strategies, and inspire future work on AI-driven scientific discovery in finance and other fields.
