摘要


本篇學位論文係以部分競拍期間的IPOs上市後之股價行為作為比較之對象,從IPOs的短期超額報酬之大小、跌破承銷價格之比例以及IPOs上市後之股價調整速度等三個角度,來剖析詢價圈購對IPOs上市後股價行為之影響。 本篇學位論文獲致如下之實證結果:臆說一「以詢價圈購為主的制度下,股票將伴隨較高之短期超額報酬」,獲得實證上強而有力之支持;臆說二「以詢價圈購為主的制度下,股價跌破其承銷價格之新上市公司佔全數公司的比例較低」,獲得實證上之支持;臆說三「在詢價圈購制度與部分競拍制度下,兩制度的股價調整速度不同」,獲得實證上強而有力之支持。取消上市後前五個交易日之漲、跌幅限制,確實可以加快股價調整至均衡價格(內生價值)的速度。綜合而言,改採詢價圈購為主新上市股票承銷制度,相較於先前採行之部分競拍制度而言,對臺灣地區新上市股票上市後之股價行為確實會產生舉足輕重之影響。

並列摘要


The present study posits that the book-building as opposed to the partial auction leads the underwriting price further away from the intrinsic value of the IPOs. It is expected that the stock price behavior of the IPOs in the aftermarket will be affected accordingly. The primary empirical findings can be summarized as follows: First, as expected, the magnitude of the average short-term excess returns is increased. Second, as expected, the percentage of the IPOs with a transaction price at the end of a certain period of listing falling below the listing price is reduced. Third, as expected, under book-building in company with the removal of price limits for the first five transaction days in the aftermarket, the speediness of price adjustment will quicken. The present study therefore concludes that the adoption of the book-building share allocation mechanism indeed changes the stock price behavior in the aftermarket for Taiwan’s IPOs.
