Immediately following an initial public offering, underwriters often repurchase shares of poorly performing offerings in an apparent attempt to stabilize the price. Using proprietary Nasdaq data, I study the price effects and determinants of price support. Some of the key findings are (1) Stabilization is substantial, inducing price rigidity at and below the offer price; (2) I find no evidence that stocks with larger information asymmetries are stabilized more strongly; (3) Larger underwriters stabilize more, perhaps to protect their reputations with investors; and (4) Investment banks with retail brokerage operations stabilize much more than other banks, inconsistent with the view that stabilization benefits primarily institutional investors.

This paper studies institutional investors’ incentives to be engaged shareholders. In 2017, the average institution gains an extra $129,000 in annual management fees if a stockholding increases 1% in value, considering both the direct effect on assets under management and the indirect effect on subsequent fund flows. The estimates range from $19,600 for investments in small firms to $307,600 for investments in large firms. Institutional shareholders in one firm often gain when the firm's competitors do well, by virtue of institutions’ holdings in those firms, but the impact of common ownership is modest in the most concentrated industries.
