Brain Sentiment Indicator / Stock Sentiment using NLP on financial news / 10000+ Global Stocks

The Brain Sentiment Indicator monitors public financial news for more than 10000 global stocks from about 2000 financial media sources in 33 languages. Each stock is assigned a sentiment score ranging from -1 (most negative) to +1 (most positive). Indicators are updated daily and correspond to the average of sentiment for each news article on two time scales; 7 days and 30 days. Volume of news contributing to sentiment scoring is also available upon request, so that weighted rankings could also be derived.
