More frequent, larger, and more recent debt and equity issues in the prior three fiscal years are followed by lower stock returns in the subsequent year. The intercept of a q-factor calendar-time regression for the value-weighted portfolio of firms with at least three large issues is -0.63% per month (t-statistic =-4.31). Purging the factor returns of recent issuers increases the magnitude of the estimated underperformance following frequent equity issues. A value-weighted Fama–MacBeth regression shows that firms with three equity issues underperform non-issuers by 0.65% per month (t-statistic =-2.65). Earnings announcement returns are low following frequent issues, especially equity issues.
