Brain Sentiment Indicator API | Intrinio

Brain Sentiment Indicator monitors public financial news for approximately the largest 8000 global stocks using about 2000 financial media sources.


  • Stay informed: leverage Brain’s proprietary automated analysis of financial news flow to gain a deeper understanding of the dynamic factors driving investor sentiment. 
  • Add depth to investment decisions: incorporate BSI’s ranking to build quantitative strategies that include sentiment as a short-term momentum indicator. Apply sentiment scores to value strategies to find companies that could be under- or over-priced mainly due to very low or high sentiment. 
  • Leverage advanced technologies and models: Brain’s robust sentiment scoring technology is based on the combination of various Natural Language Processing techniques. Algorithms have been validated by manually comparing calculated sentiment during positive and negative historical events (e.g. Facebook in 2018) for a large set of companies included in the universe.
