本文主要探討新股初次上市(櫃)前後期間的股價反應，並藉由觀察準上市(櫃)公司正式上市(櫃)前於興櫃市場交易的股價反應，來驗證興櫃市場的價發現機能。實證結果顯示，上市(櫃)申請日起至興櫃市場最後交易日止期間平均持有報酬47.01%、上市(櫃)首日異常報酬為58.37%、正式掛牌上市(櫃)第二交易日起至一年後的報酬表現，新上櫃股票報酬為14.01%普遍優於新上市的-1.23%。
興櫃市場的價格發現機能相關研究方面，興櫃市場的價格發現機能相關研究的結論為:IPO首日超額報酬在興櫃市場就已經能率先適當反應，興櫃市場是有價格發現機能的，IPO首日超額報酬存在，很有可能是因為承銷價低估。 / This research aims to investigate the performance of IPO stocks during their offering.
