中文摘要 |
以往研究指出:臺灣股市現金增資對於公司的股票價格具有顯著正面的宣告效果,這樣的研究結果與美國現金增資有負面效果的情形相反。臺灣的現金增資案可能是因為公司的成長機會而造成正的資訊內涵。以往研究在衡量宣告效果的累積異常報酬時,並未將公司成長潛力的影響考慮在內,本研究則採用了Fama-French的模式考慮了成長對公司預期報酬的影響來估計累積異常報酬。我們發現現金增資宣告平均而言對公司的股價有正面的影響,而發行公司所說明的增資用途,對於現金增資的宣告效果並沒有明顯差異。公司成長與否以及內部人交易的買進行為才是造成增資案正面效果的原因。而且這兩個因素的影響並不相互隸屬,具有成長的潛力而且公司內部人在增資宣告之前的股票買進大於股票賣出者,現金增資可以帶來股票價格的上揚;反之,若公司的成長機會不佳,而且公司的內部人在增資宣告之前大賣持股,則現金增資的宣告也會造成股票價格的下跌。 |
英文摘要 |
Previous studies show that the announcement of seasoned equity offerings (SED) in Taiwan causes the stock price to go up which is contrary to most of the empirical findings of SED announcement in US. A possible explanation for the positive SEQ announcement effect on stock price is the growth potential of SED issuers. Furthermore, previous studies ignore the influence of growth potential when measuring the cumulative abnormal return of the announcement of SEDs. which definitely bias the findings . In this paper, we employ the Fama-French model to take care of effect of growth potential on the abnormal return around the announcement. We find that on average the announcement of SED has a positive effect on stock price. However, the price run-up around announcement is not related to the us- of proceeds. We also show that the growth potential and insider buying are the true causes for the increase of the stock price and that the growth potential and insider buying do not subsume each other. SEOs with high growth potential and insider buying are the only subsample to encounter positive SED announcement effect. |
