Large language models (LLMs) are advanced artificial intelligence systems trained on vast amounts of text data to understand and generate human-like language. LLMs can perform a wide range of language tasks, including translation, summarization, question answering, and code generation. Their versatility has made them valuable tools across industries, from finance and healthcare to education and software development.
Reference [1] utilized LLMs to construct trading agents in the financial markets. Specifically, the author used LLMs to emulate various types of investors: value investors, momentum traders, market makers, retail traders, etc. The article pointed out,
First, LLMs can effectively execute trading strategies. They consistently understand market mechanics, process market information, form price expectations, and execute trades according to specific instructions. Their trading behavior is highly sensitive to the prompts they receive—they faithfully follow directions regardless of profit implications…
Second, LLMs react meaningfully to market dynamics. They consider current and historical prices, dividends, and other market information when making decisions. …
Third, market dynamics with LLM agents can resemble actual markets and mirror classic results from the theoretical finance literature. When these agents interact, they produce realistic price discovery and liquidity provision with emergent behaviors, including price convergence toward fundamental values…
These findings carry significant implications for market structure and regulation. While LLM agents can enhance price discovery and liquidity, their adherence to programmed strategies, even potentially flawed ones derived from prompts, could amplify market volatility or introduce novel systemic risks, as observed in our simulated bubble scenarios. A key concern is the potential for widespread correlated behavior: similar underlying LLM architectures responding uniformly to comparable prompts or market signals could inadvertently create destabilizing trading patterns without explicit coordination. This underscores the critical need for rigorous testing and validation of LLM-based trading systems prior to live deployment.
In short, the article concluded that trading strategies generated by large language models are effective, but could introduce new systemic risks to financial markets because these agents would act in a correlated manner.
