While IPOs have been underpriced by more than 10% during the past two decades, we find that in a sample of more than 2,000 IPOs from 1980 to 1997, the median IPO was significantly at the offer price relative to valuations based on industry peer price multiples. This overvaluation ranges from 14% to 50% depending on the peer matching criteria. Cross-sectional regressions show that overvalued IPOs provide high first-day returns, but low long-run risk-adjusted returns. These IPOs have lower profitability, higher accruals, and higher analyst growth forecasts than undervalued IPOs. Ex post, the projected high growth of IPOs fails to materialize, while their profitability declines from pre-IPO levels. These results suggest IPO investors are deceived by optimistic growth forecasts and pay insufficient attention to profitability in valuing IPOs. Copyright 2004, Oxford University Press.
