Stock Prices Move with Twitter Brand Mentions

twitter brand mentionsWhen people talk about brands on Twitter, stock prices move. This high positive correlation between stock performance and volume of Twitter mentions of a brand was just one finding in The Conversation Index Volume 5 research study from Bazaarvoice.

The study analyzed 26 million tweets with each mentioning at least one of 13 brands from the BrandZ Global 100 Brands list: Adidas, Clinique, Colgate, Gillette, Hugo Boss, Nike, Pampers, Pepsi, Ralph Lauren, Samsung, Intel, Tesco, and Sony. Next, the data was compared to over 8,000 television and radio mentions, 17 months of stock price data, over 18 months of Google search data, and 270,000 pieces of consumer-generated content from online reviews — all for those same 13 brands.

Key findings from the study include:

  • A high volume of brand mentions on Twitter typically coincides with a high stock closing price for that brand.
  • Brand buzz on Twitter typically does not fall as a brand’s stock price falls.
  • Twitter users are different from users of other social channels and are more likely to reveal their personal interactions with brands.
  • Mentions of brands on Twitter has grown by 113% from 2011 to 2012, which is lower than the 143% growth in the volume of tweets per day recorded during the same period.
  • Original tweets about brands are on the decline.
  • Retweets about brands are on the rise.
  • Google search interest in brands does not correlate to Twitter mentions, stock performance, or television and radio mentions.

Bottom-line, brand mentions on Twitter are valuable, but they differ from other types of brand mentions simply because people use Twitter differently than they use other social channels. As I’ve written many times on Corporate Eye, a fully-integrated marketing plan that leverages traditional marketing tactics and new media marketing tactics (including Twitter and other social channels)  is the most powerful and successful.
