Long†term Performance of Greek IPOs

We analyse the long†run performance of 254 Greek IPOs that were listed during the period 1994–2002, computing buy†and†hold abnormal returns (BHAR) and cumulative abnormal returns (CAR) over 36 months of secondary market performance. The empirical results differ from international evidence and reveal long†term overperformance that continues for a substantial interval after listing. Measuring these returns in calendar time, we find statistical significance with several of the benchmarks employed. We also find that long†term overperformance is a feature of the mass of IPOs conducted during a pronounced IPO wave. Cross†sectional regressions of long†run performance disclose several significant factors. The study demonstrates that although Greek IPOs overperform the market for a longer period, underperformance eventually emerges, in line with much international evidence. Our interpretation is that the persistence of overperformance over a significant interval is due to excessive supply of issues during the ‘hot IPO period’. Results associated with pricing during the ‘hot IPO period’ indicate positive short†(1†year), medium†(2†year) and negative long†term (3†year) performance.
