CHAPTER 6: Can ChatGPT Forecast Stock Price Movements? - The Revolution in Financial Analysis
Predicting stock market trends has always been a challenging task in the world of finance. Traditionally, investors and analysts have relied on a variety of methods such as fundamental analysis, technical analysis, and quantitative models to forecast stock movements. However, a new player has entered the scene, reshaping the landscape of financial analysis - large language models (LLMs) like ChatGPT.
The Evolution of Market Analysis
Historically, financial markets have been analyzed using structured data like financial ratios and market indices. But with the advancement of technology, there has been a shift towards analyzing unstructured data such as news articles, social media posts, and financial reports to gauge market sentiments. Machine learning models have played a pivotal role in processing and analyzing these vast and complex datasets with greater efficiency and accuracy than ever before.
The Rise of ChatGPT in Financial Analysis
This chapter delves into an empirical study conducted with Yuehua Tang, exploring the potential of ChatGPT in predicting stock returns based on news headlines. This study comes at a time when the AI landscape is undergoing a significant transformation with the emergence of advanced LLMs that can understand and generate human-like text. ChatGPT, a variant of the GPT (Generative Pretrained Transformer) model, represents a significant leap forward in this domain. Its unique ability to grasp context, nuance, and the intricacies of human language makes it a promising tool for financial analysis, particularly in interpreting news and textual data that impact stock markets.
