This paper investigates to which extent multifactor asset pricing models can explain the pricing of IPOs in the U.S. market between 1980 and 2015. The paper contributes to the existing literature by demonstrating that the hot market, the underpricing and the underperformance issues can be explained by the general trends and the intensities of various risk factors. We analyse the latter based on the expectation that the number of IPOs, the underpricing and the underperformance are higher when the global economy performs well. In the cases of the hot market and the underpricing, the risk factors are correlated consistently to expectations. However, this is not always the case for IPO underperformance for which coefficients differ from expectations. Finally, the risk factors identified as main predictors differ for the three IPO anomalies.
