Determinants of valuation effects for security offerings of commercial bank holding companies

In this study, the impact of security issuance by bank holding companies is examined in light of two hypotheses: the regulation or asymmetry reduction hypothesis and the bank capital hypothesis. Announcements of the issuance of common stock are associated with a significant negative effect, and the magnitude of this effect is similar to that found previously for utilities and smaller than that found for industrial firms. The market does not appear to treat subordinated debt announcements as similar to equity, although the debt qualifies as ‘capital’ for regulatory purposes. Cross‐sectional regressions do not support asymmetric information models where all unexpected external announcements are viewed negatively. Rather, the type of security being issued is an important determinant of the announcement effect.
