The underreaction hypothesis and the new issue puzzle: evidence from Japan

This article investigates the long-term equity performance ofJapanese firms issuing convertible debt and equity. We findthat issuing firms perform poorly (except for equity rightsissues) compared to nonissuing firms even though the stock-pricereaction to convertible debt and equity issues is not negativefor Japanese firms. This underperformance is strongest for firmsissuing public convertible debt. In contrast to the United States,poor performance is not concentrated in smaller firms and infirms with a high market-to-book ratio. Simple behavioral explanationsadvanced for the new issue puzzle in the United States do notseem consistent with the Japanese experience.
