This study employs the Fama-French three-factor model as well as Jensen's alpha to measure the long-run performance of IPOs in Taiwan. Our results show that the long-run performance of IPOs based on market adjusted returns or returns adjusted by market model is poor. However, the long-run performance based on Fama-French three-factor model is similar to the normal return pattern of an ordinary asset. Therefore, we conclude that the underperformance of IPOs in Taiwan is attributed to the mis-specification of the measurement model. Furthermore, we also show that the performance of IPOs in Taiwan is significantly driven by young and electronic offerings.
