    Abstract: 本計畫在 GARCH 模型架構下,利用隔夜波動(ONV)、PK 變幅、GK 變幅、
    RS 變幅、已實現波動(RV)、已實現雙冪次變異(RBP)及波動率指數(VIX)等波動
    估計式,並以那司達克-100 股價指數日報酬率作為實證標的,探討增廣GARCH
    模型的樣本外波動預測能力,並檢視各波動估計式應用於波動預測的資訊價值。
    實證結果指出波動率指數、變幅波動(PK、GK、RS)、及已實現波動(RV、RBP)
    均能提升GARCH 模型之波動預測準確性。其中,變幅波動與已實現波動估計式
    具有相當高的資訊價值、波動率指數的資訊價值較低,而隔夜波動則完全不具任
    何的資訊價值。
