Do SPAC IPOs Outperform Their Industry Peers? Evidence from the Korean Stock Market* Seung Doo Choi**?Chan Shik Jung***― Abstract―This study tracks changes in stock returns following the listing of SPAC IPOs. By identifying the factors that lead to these changes in returns, we verify the economic hypotheses implied by the SPAC IPO. Korea’s SPAC IPOs show significant positive long-term performance, unlike in the United States and unlike previous studies reported in Korea. In other words, Korea's SPAC IPO shows better long-term performance than industry peers with similar firm size and book-to-market value ratio within the same industry. These results are also confirmed in cumulative abnormal returns (CAR) and buy-and-holding period abnormal returns (BHAR) under propensity score matching and also against the benchmark using Fama-French 5-factor model. Moreover, we also find that ROA, operating cashflow over asset, sales over asset, and Tobin’s Q of a SPAC IPO firm tend to increase more than its industry peer after three years later from the SPAC IPO event day. As a result of regression analysis with CAR and BHAR set as dependent variables, the three year performance under propensity score matching was found to be further improved when audited by the top four accounting firms than those not the top four. Also, the higher the shareholding ratio of the largest shareholder was, long-term performance was found to be improving. Moreover, the higher the CAR for the five days after the listing date was, the poorer the long-term performance (winner’s curse) was. However, this winner’s curse disappeared when the product market competition was intense. That is, the winner’s curse occurred only when the competition is weak. These results support the idea that information asymmetry can harm values of SPAC IPOs and thus lifting the asymmetry can raise their stock value. An implication is that Korean-style SPAC IPO is judged to be a good policy alternative that can contribute to the development of the capital market without damaging investor value in the long run.
