隨機利率下保本型票券之評價與避險策略

Valuation and Hedging Strategy for Principal Guaranteed Note under Stochastic Interest Rates

摘要


在短期利率激烈波動的情境下,本文利用Heath, Jarrow,及Morton(19992)之遠期利率模型,以國內證券之海外分支機構於2003年1月發行的華邦電保本型票券為例,利用平賭模式推導出無套利評價公式可國內零息債券與價差買權複製而成。此外,本文亦推導出保本型票券之最適動態避險策略,提供發行者風險控管準則。實證結果發現,本文所得的理論價格與實真實市場價值接近。因此,本文所推導之公式解可供實務界參考,作為保本型商品訂價與風險控管依據。

並列摘要


Since the short-term interest rates change dramatically from 2001 to 2003, with the context of this paper uses the interest rate model of Heath , Jarrow, and Morton(1992), we take a winbond-principal guaranteed note issued by security corporation as an example and derive the closed-from solution for this note. We show this note can be synthesized by buying domestic pure discount bonds and buying bull call spread. Furthermore, we also derive the dynamic hedging strategy for principal guaranteed note. Finally, using the implied volatility obtained by call warrant with the same underlying asset, our numerical result is close to the market value.
