The rapid growth of textual data has profoundly impacted how we predict and understand financial market behavior. A recent study conducted at Telkom University has unveiled new insights into the connections between news sentiment and stock market behavior of Indonesian companies. By leveraging advanced AI-based sentiment analysis and natural language processing techniques, researchers have explored the influence of news sentiment on stock prices at individual, industry, and media co-occurrence cluster levels. The results have led to the development of a unique analytical framework that offers new perspectives on AI-driven investment strategies and highlights the potential of big data analytics in Indonesia's capital market.

Key Takeaways:

  • The study analyzed a dataset of 192,582 Indonesian financial news articles published between 2018 and 2023 to explore the connections between news sentiment and stock market behavior.
  • The research utilized AI-based sentiment analysis and natural language processing techniques, including identity recognition, network analysis, and correlation assessment.
