From this quarter Nyse Technologies will be the exclusive reseller of the SMA (Social Market Analytics) patent-pending Sentiment Signature Feed social media monitoring engine.

Nyse Technologies' subscribing customers will be able to access data from SMA's engine, which extracts, evaluates and calculates data in real-time. It uses this to attempt to generate directional and volatility indications on individual stocks, ETFs, sectors, and indices by measuring the level and quality of social media interactions.

The engine seeks to create a "social media signature", consisting of seven statistical indicators: S-Score, S-Mean, S-Delta, S-Volatility, S-Buzz, and S-Dispersion, which may allow customers to track relative sentiment, in addition to volume, change, and dispersion of commentary.

Tom Watson, VP, global market data, Nyse Technologies, says: "We believe this will change the way the financial sector thinks about social media. For the first time, trading firms, brokers, asset managers, and non-financials in every sector will have a measurable way to track the sentiment of the social media stream of consciousness."
