    Abstract: 本文運用修正後的?史模擬法(Filtered Historical Simulation,FHS)、
    GARCH-EVT模型和以Copula為基礎的FHS模型(Copula based FHS Model)三種
    方法評估國際投資組合之風險值;並進一步應用Kupiec(1995)的概似比檢定
    (Likelihood Ratio Test, LR test)和均方誤差法(Root Mean Squared Error, RMSE)
    評估風險值模型的績效。由實證結果可知次貸危機發生後,各國股價指?之間的
    關?性結構具有顯著的變動,使得國際投資組合?再具有風險分散效果。另由概
    似比檢定可知,無?是在?融危機前後,FHS模型有較佳的績效。另一方面,相
    較於傳統的線性結構,非線性關?結構的Copula 函?可以相對準確地預測風險
    值。
