We study the effects of the popular Mad Money Show on the attention of investors and financial markets. We find that the Show’s mentions/recommendations significantly affect retail and institutional investor attention, proxied by SEC EDGAR queries and posts on Stocktwits, that remain after controlling for other firm-specific news and other moderating events such as the Superbowl and Olympics. The magnitudes of the effects depend on the direction of the recommendations (buy or sell) and the emphasis allocated to a stock on the Show. The induced investor attention subsequently affects the abnormal trading volumes and short-sales activities of retail and institutional investors, and the portfolios of retail investors. No abnormal returns are associated with any pre-Show publicity about upcoming guest interviews. Significantly positive (negative) following-day abnormal returns for buy (sell) recommendations on the Show become significantly negative (positive) by day 20. Overall, our findings are consistent with the impact of the media and its potential influencers on the limited attention of investors, the short-term price pressure associated with noise traders, and the shorting of contrarian investors.
