Stock price informativeness and analyst coverage
Authors:Ahmed Marhfor  Bouchra M'Zali  Jean‐Claude Cosset  Guy Charest
Abstract:We examine whether more analyst coverage translates into more informative stock prices and apply this to both developed and emerging markets. We measure price informativeness using the association between current stock returns and future earnings. We argue that more informative stock prices contain more information about future earnings. Results indicate that analysts' activities do not contribute to the impounding of future earnings information into current stock prices, in accordance with the view that analysts are outsiders who do not have full access to firm‐level information. We also find that analysts specialize according to industry and that “industry expertise” is limited to developed countries. Overall, our evidence is consistent with the explanation that analysts focus on gathering and mapping industry‐ and market‐level information (macroeconomic information) into stock prices.
