摘要:	「或有可轉換債券」（簡稱CoCo）是2009年底新興的組合式商品，它在發行公司（或金融機構）財務狀況良好時如同一般公司債，定期支付投資者約定的利息，並於到期時償還本金；當公司財務惡化時，將「強制地」轉換成普通股。經由學者與監理者的提倡，CoCo目前在歐洲已有多間大型金融機構發行，並已被瑞士用作金融監理的工具。有關CoCo的文獻，目前大致可分為兩類，一類係站在監理者角度探討發行條款的設計，另一類重點則在評價。本論文以投資人的立場出發，探討CoCo的靜態避險策略。論文首先以「股權衍生性法」為架構，以蒙地卡羅法模擬用選擇權進行靜態避險的績效，隨後加入跳躍項允許銀行突然違約，並觀察避險績效的變化。經由分析不同參數改變下的避險績效，筆者發現，靜態避險能有效降低標準差與風險值（VaR）。在不考慮違約時，避險效率會隨波動度增加而提升；在考慮有違約時，相同參數下，避險效率會比不考慮違約時高出許多，同時績效也會隨著違約機率增加而提升。 Contingent Convertible Bond, aka CoCo, is a new form of financial product initiated by the end of 2009. When the issuing companies (or financial institutions) are solvent, the CoCos are similar to corporate bonds, investors receive periodic interests and principal repayment at maturity; when they become insolvent, however, the CoCos will be mandatorily converted into common shares. Being advocated by many academics and regulators, CoCos have now been issued by a number of major European financial institutions, and have been used as the Swiss financial supervisory tools. So far the literatures about CoCo can be broadly divided into two categories, with one category stands on the perspective of regulators, trying to figure out an optimum CoCo indenture; and the other focuses on CoCo valuation. In this thesis, we discuss the hedging strategies for CoCo from an investor`s standpoint. Firstly, based on the “equity derivatives method” framework, this thesis uses Monte Carlo simulation to evaluate the performance of static hedging with option; then followed by adding a jump diffusion term to allow banks to suddenly default. By analyzing changes in hedging performance under different parameters, the researcher found that static hedging can effectively reduce the standard deviation and the value at risk (VaR) of entire portfolio. Without considering defaults, hedging effectiveness will improve when the volatility of stock return increases; after considering defaults, the hedging effectiveness becomes much higher under the same parameters assumption. Moreover, the researcher found that hedging performance improves as the default probability increases.
