The Impact of All-Star Analyst Job Changes on Their Coverage Choices and Investment Banking Deal Flow

Using a sample of all-star analysts who switch investment banks between 1988 and 1999, we examine (1) whether analyst behavior is influenced by investment banking relationships and (2) whether analyst behavior affects investment banking deal flow (debt and equity underwriting and corporate control transactions). Although the stock coverage decision is dependent on the investment banking relationship with the client firms, we find no evidence that analysts change their optimism or recommendation levels when joining a new firm. Investment banking deal flow is related to analyst reputation only for equity underwriting transactions. For debt underwriting and Mamp;A transactions, after controlling for bank reputation, analyst reputation does not matter. There is no evidence that issuing optimistic earnings forecasts or recommendations affects investment banking deal flow
