  • Sentiment Score: A measure of the bullishness / bearishness of the language used in media for a given stock on a given day. Ranges from -5 (extremely negative coverage) to +5 (extremely positive coverage); a score of 0 indicates an absence of articles for that day. Alternatively, scores may also be expressed on a 0 to 10 scale with 0 still indicating an absence of articles for that day, 1,2,3 a negative score, 4,5,6,7a neutral score, and 8,9,10 a positive score. The overall sentiment score is computed as a weighted average of sentiment scores over news titles, headers and company specific phrases. A significant correlation between news sentiment and stock prices is observed across most listings.

  • Sentiment Low: The intraday minimum value of the sentiment score, polled at 5minutes intervals.
  • News Volume: The number of news articles about this stock, published and parsed on a given day. Volume of news provides a good indicator of a trend breakout or a trend reversal.
  • News Buzz: A measure of the rate of change in news coverage of a given stock on a given day, normalized on a scale of 1 to 10. The buzz score measures the change in the standard deviation of periodic news volume. It can be thought of as the "rate of change of news"; it thus serves as a risk alert indicator.
