摘要


在過去幾年中,擔保債權憑證這類型的信用資產投資組合是所有資產擔保證券中成長最快速的。因此,提高了風險管理對於信用資產投資組合的需求。然而,在大部分的信用資產投資組合中,其所包含的資產異質性相當高。由於上述的原因,造成信用資產投資組合在風險衡量方面愈益複雜。在本篇論文中,我們結合內部價值法以及因子關聯結構所計算出的預期回收率,將有助於我們對於風險性債券投資組合這類型信用資產投資組合進行信用風險調整,以便於計算風險性債券投資組合每天的風險值。

Credit portfolio assets such as CDO (collateralized debt obligation) have the highest growth among all asset backed securities. This increases the demand for risk management of credit portfolio assets. Since most credit portfolios comprise heterogeneous credit assets, it makes the risk evaluation more complicated. This study combines an intrinsic valuation approach with factor copula to estimate endogenously expected recovery rate that are useful in estimating credit adjusted VaR of credit portfolios such as risky bond portfolios.
