Sentiment History (Index)

No algorithm description given

Sentiment History (Index) This API returns News Sentiment data aggregated by major stockindex. Input : Index Id (see https://algorithmia.com/algorithms/infotrie/Index) and Format. Output: Detailed sentiment history of the company including sentiment score, Sentiment high / low, News Volume, News Buzz and Date. Indicators Description: 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 High: The intraday maximum value of the sentiment score, polled at5 minutes intervals. 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.

 "volume": 3352,
 "date": "29-04-2015",
 "sentiment": "5.641",
 "buzz": "5.191"

Internet access

This algorithm has Internet access. This is necessary for algorithms that rely on external services, however it also implies that this algorithm is able to send your input data outside of the Algorithmia platform.


Calls other algorithms

This algorithm has permission to call other algorithms. This allows an algorithm to compose sophisticated functionality using other algorithms as building blocks, however it also carries the potential of incurring additional royalty and usage costs from any algorithm that it calls.


To understand more about how algorithm permissions work, see the permissions documentation.
