摘要

本研究測試台灣 2008 年至 2016 年股票市場上各種事件後的庫藏股買回宣告效果。研究上將庫藏股宣告前之特定事件區分為現金增資及發行公司債券兩種，並比較這兩種事件後宣告買回庫藏股之效果。本研究之資料來源為台灣經濟新報資料庫，共蒐集 2858 件庫藏股買回事件，其中有 105 次庫藏股宣告之前一年亦宣告進行現金增資，而有 299 家次庫藏股宣告前一年發行公司債。

本研究主要發現庫藏股宣告前企業之異常報酬為負值，而宣告後之異常報酬為正，顯示庫藏股宣告對股價有正面的助益，尤其在宣告後的第一天更為明顯。而前一年先進行現金增資，再宣告買回庫藏股的效果雖然有向上的趨勢，但是累積宣告效果始終為負值，亦即對股價不會有正面的助益。而企業在前一年有發行公司債券者，則在第二年進行宣布買回庫藏股之效果為正，顯示這樣的財務操作模式對於股價有正面的幫助。

關鍵字: 庫藏股，買回庫藏股，連續事
