Our paper examines whether investor opinions expressed in social media predicted stock returns of financial firms during the 2007–2009 global financial crisis. We conduct a textual analysis of the articles published on the stock market insight website Seeking Alpha before the crisis and find that banks that were described in articles with a higher fraction of negative words experienced (1) sharper drops in stock prices, (2) larger increases in expected default probability, and (3) greater surges in nonperforming loans during the crisis. Our evidence suggests that wisdom of crowds provides valuable information on how banks weather a forthcoming crisis.
