The outcomes of many activities depend upon both skill and luck. The authors analyze stock analysts’ forecasts of companies’ earnings per share under market conditions that vary in volatility and thus imply different levels of luck in outcomes.Noting that making forecasts that deviate widely from the consensus of their peers—which is observable by the analyst—potentially carries both career-related rewards but also reputational risks, the authors examine the degree of deviation from consensus exhibited by analysts of different skill levels (measured by both past forecasting accuracy and education) in different market conditions.The authors find that average deviations from consensus increase as markets become more volatile. At the same time, low-skill analysts exhibit larger increases in deviations from consensus than high-skill analysts.The authors suggest possible interpretations for these findings and directions for future research.
