評價擔保房貸憑證-使用延伸樹法 / Pricing CMO by Extended Tree Method

楊松峰 Unknown Date (has links)
本研究以Kishimoto(2004)提出之延伸樹法(ET Method)結合Hull-White利率三元樹建構出一節點未重合之三元樹(Non-Recombining Trinomial Tree),利用此三元樹對CMO中之序列還本類組(Sequential Pay)、純本金/純利息類組(PO/IO)、計畫性還本類組(PAC)之各分券進行評價,並進行各分券價格對各參數之敏感度分析。 我們發現除了純利息類組(IO)外,外在提前還款率上升使得CMO各分券之價格上升;此外,期初零息債券殖利率曲線水平往上移動使得CMO中除了純利息類組(IO)外,其他分券價格皆下降;至於利率均數回歸係數變大則主要使得除純本金類組(PO)外之CMO大部分分券價格上升;最後,即期利率波動度變大使得除了純本金類組(PO)之外的CMO各分券價格皆下降。
