한국 IPO 시장에서 투자주체별 투자경쟁률이 장단기 주가수익률에 미치는 영향에 대한 실증연구

This study empirically investigates whether the investment competition rate by investor type (institutional demand prediction competition rate, general public offering competition rate, and employee stock subscription rate) in the Korean IPO market is informative in predicting future stock prices after IPO. The results of analyzing the IPO sample from 2001 to 2021 are as follows. First, we find that firms with a high competition rate for institutional demand forecasting have more efficient public offering prices and an increased external monitoring effect, reducing long-term underperformance anomalies. Second, we find that firms with high public offering subscription rates show increased short-term overreaction behavior after an IPO and increased underperformance anomalies in the long term. Third, we find that firms with a high employee stock subscription rate partially reduce long-term underperformance for two years after their IPO. Overall, this study’s results empirically show that non-financial information (investment competition rate) available in the IPO market is useful for evaluating the quality of IPO firms and predicting future performance.
