As the regulation of public companies has progressively tightened in recent years, many companies have chosen to switch to stock exchanges with lower regulatory requirements. We analyse the consequences of switching for smaller quoted companies, using the unusual regulatory environment in London, which has two markets with different regulatory regimes but the same trading technology. Firms that switch to lighter regulation experience negative announcement returns of approximately 5%. However the initial price reactions are reversed after the actual switch - these firms experience a longer-term upward drift in stock returns, which we relate to improved operating performance.
