Sell‐side analysts' recommendations a value or noise

The main objective of the paper is to investigate the analysts’ recommendations’ value and to determine on which market the analysts have more predictive power that can be defined as an extent of a stock price’s reaction around a particular recommendation what leads to abnormal returns of the security. Such recommendations are significant in decision‐making whether to buy or to sell a particular stock. We observed 1,881 events from 168 companies traded at the London Stock Exchange and the New York Stock Exchange in a period between January 1, 2016, and April 31, 2019. We used an event study analysis and classical one‐factor market model to determine expected returns for a particular stock in an estimation window. It was found that both American and European Union markets are feasible to be outperformed by the analysts but it is impossible to highlight any of the markets as they behave almost identically around positive, neutral and negative recommendations.
