本研究藉由對「市場擇時(market timing)」與「市場條件(market conditions)」兩假說之驗證,來探討台灣上市公司辦理現金增資的動機,據此建議投資人較佳的投資決策。實證顯示,若公司經理人發現該公司股價被高估時,會傾向於進行現金增資,符合市場擇時假說,即存在著市場擇時行為;另外,當經理人做現金增資決策時,較少考慮『未來』市場條件的變動,亦即較不受到市場條件變動的影響(不符合市場條件假說),故本研究實證結果偏向支持「市場擇時假說」,而對「市場條件假說」採取保留態度。因此本文認為,上市公司辦理現金增資後,短期內其股價向下調整的可能性較高,故建議投資人宜採「長期持有」股票的投資策略,或降低持有「剛辦理現金增資公司股票」的比重。
This study examines the issuing motives of seasoned equity offerings (SEOs) by verifying market timing and market conditions hypotheses. The results evidence that firms with the higher ratio of market value to book value tend to undertake SEOs (i.e., utilization of overpricing), but they have less consideration for the changes in market conditions (e.g., expected market return, expected aggregate profitability, or prior uncertainty). It shows that firms attach more important to past and immediate market returns but expected market situations. Therefore, our findings tend to support market timing hypothesis but to have reservations for market conditions hypothesis.
