摘要


這篇論文主要欲探討公司是否可以利用現金股利的宣告,來達到操縱股價的目的。由於許多教科書認為投資者與管理者間存在資訊不對稱的問題,因此公司不應同時宣告發放現金股利以及發行新股票,然而,在資料蒐集的過程中,仍然發現有少數的公司在發行新股前做了發放現金股利的宣告。因此,就產生了這些公司「是否欲利用現金股利來操縱公司股價」之懷疑。假使管理階層真的有意運用因為宣告現金股利所產生對市場上正面的影響,進而使公司接下來能以較高的價錢在市場上發行新股,則我們預測這些公司其實並沒有足夠的能力執行其對股利的承諾,因此其營運表現應比起其他公司來的差。故此論文著重於探討發行股票公司與未發行股票公司其股利政策是否有顯著的不同;若有,則繼續探討公司在發行新股之前,宣告現金股利之消息,對股價所產生的影響,以及這些公司發行股票後續的營運表現。而由實證資料發現,發股公司確實有比較大的誘因在發行股票前宣告現金股利,而其中,宣告股利增加及股利不變的發股公司確實達到操縱股價的目的,得以以較高的價格發行新股。然而,在後續的研究中,我們卻發現這些公司營運不佳,無法實現其對投資者所承諾的股利宣告,進而造成價格反轉的情形較其他公司更為嚴重。

This article examines the relation between dividend and stock offering decisions. Managers rely on dividends to obtain a higher price in stock offering but contributed to the more severe price reversion after issuing than others. The evidence shows that the dividend policy of issuing firms differs considerably from that of nonissuing firms. In simple terms, issuing firms are more likely to declare dividends than nonissuing firms. Moreover, the data detected obvious benefits in the data from linking dividend and stock offering decisions. In particular, dividend decisions appear to lead to positive announcement effects. Amid those suspected firms which have manipulated the stock price, only firms increasing cash dividends prior to the stock offering have succeeded in their inferior achievements accounted for more serious reversed price reactions.
