本研究利用事件研究法(Event Study)、Wilcoxon-T檢定以及T檢定,來檢驗當私募股權基金宣布併購台灣目標公司時,目標公司是否具有顯著性的宣告報酬,以及當目標公司是否為金融業、交易規模高低、持股比例高低、併購溢價高低是否會影響到該目標公司之宣告報酬。私募股權投資基金併購標的通常是具有價值低估、具備高度成長性、技術領先性的公司。Ljungqvist and Richardson (2003)中提到私募股權的報酬率高於標準普爾指數5-8個百分點,而本篇論文的基於先前的研究結果下,探討在台灣1999年至2015年間,發現市場接收到私募股權投資基金入股企業的消息後,會將其判斷為利多反應在股價上,具有顯著性之宣告效果。
