ChatGPT can't see the future, but it already has value for investors looking to predict future moves in the stock market. That's according to a new research paper published Monday in the Social Science Research Network by two University of Florida finance professors.
- The researchers fed over 50,000 news headlines to a chatbot and used sentiment analysis to determine whether the headlines were good, bad, or irrelevant for companies' stock prices. The chatbot's scores were found to have a statistically significant positive correlation with the next-day stock performance of the analyzed companies.
- The study suggests that using advanced language models, like ChatGPT, in investment decision-making can lead to more accurate predictions and enhance the performance of quantitative trading strategies.
- The study also found that ChatGPT outperformed traditional sentiment analysis methods in predicting stock market returns.
- Impact: AI tools like ChatGPT could be used to improve the stock market's efficiency by incorporating news faster into stock prices. He also said these tools could replace some investment analysts.
- Cautions:
- ChatGPT, a language model based on GPT-3.5, is not connected to the internet and therefore lacks access to the latest information beyond its training cutoff in September 2021.
- This limitation hinders the model's ability to provide up-to-date insights on market trends, news, or developments that could impact investment decisions. Additionally, the model struggles with processing large texts and numerical data like accounting data.
