When AI Meets Finance (StockAgent): Large Language Model-based Stock Trading in Simulated Real-world Environments

arXiv:2407.18957v5 Announce Type: replace-cross Abstract: Can AI Agents simulate real-world trading environments to investigate the impact of external factors on stock trading activities (e.g., macroeconomics, policy changes, company fundamentals, and global events)? These factors, which frequently influence trading behaviors, are critical elements in the quest for maximizing investors' profits. Our work attempts to solve this problem through large language model based agents. We have developed a multi-agent AI system called StockAgent, driven by LLMs, designed to simulate investors' trading b

Why this matters
Why now

The rapid advancement and sophistication of large language models are enabling their application to complex, real-world financial simulations, moving beyond theoretical models to practical agent-based systems.

Why it’s important

This development indicates a significant step towards autonomous AI agents directly influencing or participating in financial markets, impacting traditional analytical roles and potentially market dynamics.

What changes

The ability of AI systems to simulate and interact with financial markets in a 'real-world' manner changes how market analysis, strategy development, and risk assessment can be performed.
