To see how Bloomberg captures sentiment, take a look at Regeneron Pharmaceuticals Inc., one of the best-performing U.S. “Sentiment analysis helps derive meaning from the stream.” “Social signals provide another tool for investors to identify trends and events that may move or influence markets,” said Brian Rooney, Bloomberg’s Head of Product for News, Economics and Specialized Content. The system relies on algorithms developed by a team of PhDs, product managers and R&D professionals incorporating statistical models and years of Twitter history applied to financial markets. Sophisticated tools are used to measure a tweet’s sentiment. From there, subscribers can see the overall volume of tweets and the mix of positive, negative and neutral comments, and can click their way to individual Twitter postings, which are available directly through the terminal. BSV monitors the flow of tweets about each stock and triggers an alert whenever sentiment crosses a particular threshold. Users can set up an alert to watch, for example, all of the tickers in the S&P 500 and be alerted to those with significantly positive or negative social sentiment.
To answer that, Bloomberg also provides social sentiment analytics. The real question is: why is this topic important? Is the rise of interest in a company positive, negative, or neutral? When tweets start jumping, an alert is pushed out.īut knowing a topic is trending isn’t always enough for investors. With BSV, users don’t have to stare at a stream of tweets all day waiting for a spike in activity. To track a company, BSV scans tweets and StockTwits for so-called cashtags, social media’s way of indicating news about a stock, and any mentions of the company’s name. Using Bloomberg Social Velocity (BSV) alerts, Bloomberg subscribers can see social media volume about, say, Ford, BP, or Samsung. When Bloomberg integrated Twitter feeds into our platform via TWTR in April 2013, we also provided users the ability to monitor for unusual bursts of social media chatter about a company. That’s why Bloomberg provides subscribers with social sentiment tools, which categorize opinion and provide charts and visualizations based on this data.
Knowing the fast-moving social sentiment of a particular investment opportunity could provide a trader with that extra edge.
What Twitter does for the reputation of Lady Gaga or Bill Gates also applies to companies and stocks. This is the “sentiment” of the Twittersphere. If you’ve spent any time on Twitter, you know that tweets can be snarky, informative, nonsensical, hilarious, and sometimes provocative.
