What Happened
The new S&P 500 Twitter Sentiment Index Series consists of two indices:The S&P 500 Twitter Sentiment Index, which measures the performance of 200 S&P 500 constituents with the highest sentiment scores.
The S&P 500 Twitter Sentiment Select Equal Weight Index, which measures the equal-weighted performance of 50 S&P 500 constituents with the highest sentiment scores.
The indices will monitor Twitter user sentiment daily by analyzing tweets containing $cashtags for a stock symbol; In Twitter’s case, $TWTR. S&P Dow Jones Indices will absorb these tweets in real-time through Twitter’s API in order to determine an overall “z-score” measuring the level of positive sentiment surrounding each company. The indices will rebalance at the beginning of each month.
