Research background: The study examines the performance of companies that are going public with equity issuance (IPO) in Poland.Purpose: Some scholars argue that the buy-and-hold strategy that has been quite widely used suffers from cross correlation and the “bad model” problem. Hence, the calendar-time portfolio approach is used to extend the methodology.Research Methodology: The empirical procedure is two-step. At the beginning, we calculate an average abnormal return for the portfolio of IPOs firms. The portfolio is rebalanced each month. Next, the risk-adjusted performance is measured by regressing returns on a multifactor time-series regression model. We employ the Fama-French (1993) three-factor model and CAPM for the robustness check.Results: In a sample of IPOs listed on the Warsaw Stock Exchange, we find negative and highly significant abnormal returns. Alphas are statistically significant in all of the Fama-French regressions and in most of the cases for CAPM.Novelty: This paper discusses the puzzle of the long-term equity performance of initial public offerings (IPOs) using the calendar-time portfolio approach. Our results point to the economic and statistical significance of long-term IPO underperformance.
