Resumen
This study tests possible sources of long-term risk-adjusted returns on initial public offerings (IPO) in Poland under the calendar-time portfolio (CTP) approach. The moment of going public still remains a puzzle in many areas. Poland?s status as an emerging market has been indisputable for many years, though improvements in capital market infrastructure have led to its recent reclassification as a developed country. It is an important European equity market. Thus, research on IPO pricing explanation for Poland is important for both investors and academics. In this study, we estimate risk premiums and run regressions on four asset pricing models, including the latest innovation, which is the Fama-French 5-factor model. We also check the robustness. The research documents the existence of the long-run underperformance for Polish IPOs independently of the specification of the calendar-time portfolio approach as alphas range from -9.6% to -13.2% annually. We show that the underperformance is mainly driven by IPOs in a position of weak pre-issue financial health. More profitable IPOs experience less negative long-term returns and the underperformance is even absent in some specifications.
