The first objective is to provide evidence on long-run underperformance or over performance. Hence, IPOs underperformed the benchmark in the long-run subject to Event-time Approach. The second objective is detecting the changes in the performance of IPOs relatively to Market-adjusted-Average Cumulative Abnormal Returns and Buy-and-Hold Abnormal Returns. Thirdly, the analysis discusses how risk-return characteristics differ between two IPO samples. Post-war IPOs appear to be less risky while pre-war IPOs revealing higher risky and subject to non-systematic risk in the long-run, yet with same magnitude of returns. Authors believe that investors can use this information to identify profitable strategies to overcome long-run underperformanceenInitial Public OfferingsLong-run performanceCumulative abnormal returnsBuy-and-hold abnormal returnsRisk-return characteristicsArticle
