    Abstract: 本研究採用 GARCH(1,1)作為波動基準模型,並在其條件變異數方程式中考
    慮不同資訊頻率的已實現波動(Realized volatility, RV)作為解釋變數,另提出
    GARCH-RV5、GARCH-RV10 及GARCH-RV30 等競爭模型,進行台指選擇權之
    理論價格預測,探討高頻日內資訊能否提升GARCH 模型對選擇權價格的預測準
    確性。實證結果發現,GARCH-RV-based 模型的預測績效均優於GARCH 模型。
    因此,RV 確實能提升GARCH 模型對選擇權標的資產的波動預測準確性,進一
    步得到較佳的選擇權價格預測。此外,不同頻率的日內資料對GARCH 模型為基
    礎的選擇權價格預測均具備資訊價值,且最適頻率為10 分鐘。
