An examination of board stability and the long-term performance of initial public offerings

We study the long-term stock performance of initial public offerings (IPOs). We examine how past performance affects the board of directors' stability and how changes in boards affect subsequent performance. We introduce a dynamic, scale invariant stability metric to measure such changes. Our results indicate that among IPO firms, those with poorer initial performance experience greater board instability and that greater board stability is associated with improvement in subsequent performance. These results indicate that board members leave poorly performing firms, rather than shareholders replacing ineffective boards. Retaining boards that experience initial good performance is associated with continued success.
