Stewardship, institutional investors monitoring, and firm value: Evidence from the United Kingdom

Abstract

Stewardship encourages institutional investors to perform a monitoring function through cooperation and collective action. The United Kingdom was the first country to publish a Stewardship Code. This motivates us to investigate the monitoring role of institutional investors in the UK. We find that institutional ownership has a positive influence on firms' one-year future valuation and quality of corporate governance practices. The positive relationship identified is mainly driven by independent and long-term (ILT) institutional ownership. We additionally demonstrate that acquirers with higher ILT institutional ownership make better acquisition decisions. The performance of cross-border acquisitions does not differ from the performance of domestic deals. Overall, our results are consistent with the view that ILT institutional investors contribute to firm monitoring and promoting sound corporate governance practices, which can be attributed to their long-term investment horizons and arm’s-length relationships with investee companies.
