Current theories of capital structure have difficulty explaining the aspects of financing behavior we document. In contrast to the tradeoff theory, seasoned equity offers frequently move firms away from their target leverage ratios. At odds with the pecking-order theory, SEO firms typically are...

Prior studies have documented that firms' operating performance deteriorates following seasoned equity offerings (SEOs). This paper proposes and empirically tests the hypothesis that the poor performance is caused by managers' overinvestment. I show that, subsequent to the offering, SEO firms...
