This AI research from the University of Chicago explores the financial analysis capabilities of large language models (LLM)

GPT-4 and other large language models (LLMs) have proven to be very proficient at analyzing, interpreting, and generating text. Its exceptional effectiveness extends to a wide range of financial sector tasks, including sophisticated disclosure summarization, sentiment analysis, information extraction, report production and compliance verification.

However, studies are still being conducted on its role in making informed financial decisions, especially when it comes to numerical analysis and judgment-based tasks. Because LLMs are good at processing and producing language-based material, they perform well in textual domains. Their skill set allows them to help with tasks such as compiling compliance reports, extracting important information from massive data sets, performing sentiment analysis on market news, and summarizing complex financial paperwork.

However, the fundamental question is whether LLMs can be applied to financial statement analysis (FSA), a field that has historically placed a strong emphasis on numerical data and human judgment. Financial statement analysis (FSA) involves evaluating a company's financial condition and forecasting its future results using its financial statements, including revenues and balance sheets. In addition to being purely mathematical, this requires a deep understanding of the company's financial ratios, trends, and related information.

In recent research, a team of researchers at the University of Chicago studied the possibility that a large language model like GPT-4 could perform financial statement analysis in a manner similar to that of trained human analysts. The team provided GPT-4 with standardized, anonymous financial statements to analyze and forecast future earnings direction. Crucially, the model only received the numerical data seen in the financial records; no industry-specific narrative or information was provided.

GPT-4 proved to be better at anticipating changes in profits than human finance professionals. This dominance was especially notable in situations where human analysts often struggle. This implies that even in the absence of contextual narratives, the LLM has a clear advantage in handling complex financial facts.

Furthermore, the predictive power of GPT-4 was shown to be on par with popular machine learning models that are specially trained for these types of tasks. With performance comparable to specialized predictive models, GPT-4 can analyze and interpret financial data with high precision.

The results included the critical finding that GPT-4's predicted accuracy is independent of its training memory. Rather, the model uses the data it analyzes to produce insightful narratives about how a company will perform in the future. In addition to outperforming human analysts and corresponding specialized models, the team also examined the usefulness of GPT-4 forecasts in business tactics. Compared to strategies based on other models, these strategies based on the model forecasts produced higher alphas and Sharpe ratios. This indicates that trading strategies based on the predictions made by GPT-4 were not only more successful but also provided superior returns when adjusted for risk.

In conclusion, these findings imply that LLMs such as GPT-4 may be crucial in financial decision making. Coupled with their strong performance in real-world business applications, LLMs' ability to accurately analyze financial statements and produce insightful predictions suggests that in the future, they may even completely replace certain tasks currently performed by human analysts.
