Monthly Portfolio using Twitter S-Buzz

Messages from Twitter provide useful information for security selection. Aggregating these messages and creating social sentiment scores can yield insights. Using Context Analytics Twitter S-Buzz score, customers can create portfolios that outperform the market.


Context Analytics (CA) provides 15+ metrics as part of the standard S-Factor feed. One of those metrics is S-Buzz, a measure of unusual activity on a security compared to the universe of stocks. A higher S-Buzz indicates a security has more messages in the previous 24 hours than it typically does compared to all other stocks.

We created a monthly portfolio that takes the exponentially time-weighted average of S-Buzz over the previous month. This shows which securities over the past month had the most unexpected high message volume on Twitter. It also weights securities with high chatter in recent days more than securities with high chatter earlier in the month. After taking the top 50 securities within the S&P 500 universe with the highest exponentially time-weighted average monthly S-Buzz, we place them in an equally weighted portfolio.
