Limited attention, salient anchor, and the modified MAX effect: Evidence from Taiwan’s stock market

Abstract

The literature documents that investors overweighing the right-tail probability pursue positively skewed assets, leading to lottery-like stocks overpriced. We find that the lottery anomaly primarily exists among stocks further away from their 52-week high prices. After attention-grabbing events with gambling features, inattentive retail investors become aware of certain stocks’ gambling traits and then net buy more lottery-like stocks, which further promotes the lottery anomaly. However, when such stocks are near their 52-week high price, retail investors tend to place little weight on the likelihood that the stock price will rise beyond the 52-week high, thereby reducing the skewness preference. Overall, our findings suggest that the perception of the 52-week high price as a price ceiling influences skewness preference, and that investor attention is the main determinant of whether anchoring bias affects skewness preference.
