Twitter announced a partnership with S&P Dow Jones Indices on Thursday to build the S&P 500 Sentiment Index for monitoring the performance of 200 S&P members based on tweets with company $cashtags. Jared Podnos, strategic market development lead at Twitter, and Peter Roffman, global head of innovation and strategy at S&P Dow Jones Indices, joined Cheddar to provide some background on the partnership and to explain exactly how monitoring companies through public opinion will work. "[The S&P] taps into this conversation. They understand the real-time conversation as well as the historical trends, and then we can analyze that and understand the consumer sentiment and really build these innovative products around that conversation," Podnos added.
