We analyze the impact of sovereign wealth fund (SWF) investments on firm values and provide evidence consistent with the tradeoff between the monitoring and lobbying benefits versus tunneling and expropriation costs of SWFs as blockholders. The data show significant positive (negative) returns to announcements of SWF investments (divestments). The returns are non-monotonic, first rising (falling) and then falling (rising) with the share sought (sold) for investments (divestments). Moreover, we find that SWFs are often active investors. Slightly more than half of the target firms experience one or more events indicative of SWF monitoring activity or influence.

A prominent motive for corporate venture capital (CVC) is the identification of entrepreneurial-firm acquisition opportunities. Consistent with this view, we find that one of every five startups purchased by 61 top corporate investors from 1987 through 2003 is a venture portfolio company of its acquirer. Surprisingly, our analysis reveals that takeovers of portfolio companies destroy significant value for shareholders of acquisitive CVC investors, even though these same investors are “good acquirers” of other entrepreneurial firms. We explore numerous explanations for these puzzling findings, which seem rooted in managerial overconfidence or agency problems at the program level.
