This paper shows investors’ lottery preference can attenuate price underreaction to extreme good earnings news. Such news reaffirms investors’ preference for stocks with strong ex ante lottery-like features, thereby accelerating price adjustments. We find that PEAD attenuates for stocks with high expected skewness and extreme good earnings news. Consistent with its reaffirmation role, extreme good news strengthens the predictive power of expected skewness for highly right-skewed stocks’ future skewness. Individual investors buy more right-skewed stocks upon extreme good earnings news than other stocks and the attenuation of PEAD is concentrated in stocks with large individual net-buys. We also find a feedback loop of skewness preference: the reaffirmation of preference is associated with stronger short term price reactions to earnings news; these reactions predict greater future skewness, i.e., the stock becomes even more attractive to skewness preferring investors after earnings news.
