    Abstract: 股神巴菲特認為,對於絕大多數沒有時間研究上市公司基本面的投資人來說,指數股票型基金(ETFs)會是他們投資股市的最佳選擇。事實上,指數股票型基金早已成為普羅大眾所熱衷的被動式投資工具,而美國SPDRs 是全球最受歡迎的ETF 之一。因此,本計畫在GJR 波動模型架構下,考慮隔夜波動度、PK 日變幅及恐慌指數(VIX)等波動估計式,並以美國SPDRs 作為實證標的,探討增廣GJR 模型的風險值預測績效。實證結果發現大多數的情況下,加入各波動估計式之後的增廣GJR 模型,其風險值的預測績效顯著優於傳統GJR 模型。亦即,隔夜波動度、PK 日變幅及恐慌指數均有助於提升GJR 模型的風險值預測準確度。本研究結果有助於風險管理者合理評估ETF 的風險值,並做好潛在損失的控管,進而提升風險管理績效。
