  • 本篇論文利用CPPI策略模擬信用衍生性商品,進行信用CPPI投資組合淨值分析,並且做其風險衡量和敏感度分析。本篇論文採用Variance Gamma模型,模擬信用價差動態,並且利用Gaussian Copula模擬信用違約的時間點,結合價差動態和信用違約的兩個模型,探討CPPI策略下的投資組合淨值分析與風險探討。
    在本文可以看到以下重要結果,首先是模擬信用CPPI的過程,根據CPPI策略底下的拆解項,分析影響策略績效的情形。第二點是CPPI缺口風險的分析探討,列出可能造成缺口風險的原因。第三點為利用不同的目標乘數,模擬信用CPPI資產組合淨值的表現,可以發現在目標乘數比較低的時候,藉由蒙地卡羅模擬,平均CPPI投資組合淨值下來表現較好,反而目標乘數越大,投資組合淨值表現越不好。第四點為敏感度分析,在價差模型中的峰態係數變動下,影響CPPI投資組合淨值較大,峰態係數越大,會導致投資組合淨值表現越差。
