The evidence reported in this paper suggests that institutional investors capture a large fraction of the short-run profits associated with IPOs. The favored status enjoyed by institutional investors in underpriced offerings appears, however, to carry a quid pro quo expectation that they will participate in less-attractive issues as well. This finding conforms with the Benveniste and Spindt (1989) and Benveniste and Wilhelm (1990) prediction that U.S. underwriters behave strategically in the allocation of IPOs.
