This paper examines the relation between changes in firm value associated with public equity issue announcements and management ownership, nonmanagement large block ownership, institutional ownership, information variables, and leverage. A significant negative relation is found between the ratio of announcement period abnormal returns to changes in management ownership and the level of management ownership. This result is consistent with Stulz (1988) who predicts that firm value increases at a decreasing rate as management control of voting rights increases. This finding is also consistent with improvements in alignment of interests, where such improvements diminish as management becomes entrenched. The announcement period abnormal returns appear to be unrelated to outside blockholdings (large block ownership or institutional holdings), information variables, or leverage.
