We propose that firms use stock splits as a means of attracting attention and inducing information production to correct price distortion caused by investors’ 52-week high anchoring bias. Our analysis shows that firms are more likely to split stocks when their prices are near 52-week highs, especially if they are highly profitable and undervalued. After splits, undervaluation gradually disappears. Moreover, these splits are associated with a slower market reaction and a more positive post-split drift, consistent with the notion that investors’ anchoring bias hinders price adjustment, leading to a gradual price correction. In addition, the likelihood of such splits increases with CEO wealth-performance sensitivity, and investment-price sensitivity increases following splits. Our evidence suggests that firms utilize stock splits to correct mispricing induced by investors’ 52-week high anchoring bias.
