摘要


過去諸多關於庫藏股研究探討事件宣告買回前後之異常報酬,本研究透過庫藏股買回註銷股本,探討經營階層是否因經營績效及業績衰退等因素,藉由瘦身改善財務結構達到預期之改善效果,以及庫藏股買回註銷再增資其背後所代表之意義,最後探討事件宣告時股市異常報酬情形,進而判斷是否在事件宣告時市場交易有無異常發生之情事。 藉藉由此分析流程讓投資者更清楚面對企業進行庫藏股註銷減資時該如何抉擇,及在一波波的減資行為後政府應該如何面對,是否藉由政策之調整協助企業再進一步整合經營方向,為股東創造最大的價值。

In recent years many studies have been performed about stock repurchase programs regarding abnormal returns around event announcements. This paper will probe the factors for the decline of operating performance and corporate business achievement, the reasons managers decide to reduce capital by purchasing stock from the stock market to improve their finance structure, and then re-increase capital. Finally this paper will look at the relationships between abnormal returns and stock repurchase announcements. The study results show how investors can benefit from event announcements by reducing capital through stock repurchase and how changing current government policies can further enterprise integration which will create greater value for stockholders.
