Reverse splits in international stock markets: Reconciling the evidence on long-term returns

摘要

Do firms conducting reverse splits underperform or overperform in the long run? To resolve this question we investigate the long-term returns following more than 5000 reverse splits conducted in 24 developed equity markets between the years 1990 and 2016. Using the calendar-time portfolio approach, we demonstrate that reverse splits lead to subsequent underperformance, except for microcaps in the sample. This phenomenon is present in all the global regions we examined—North America, Europe, and Asia-Pacific—and is robust to many considerations.
