台股指數期貨動態避險效果之探討

Dynamic Hedging in Taiwan Stock Index Futures

摘要


自從新加坡國際金融交易所(SIMEX)於1997年1月將摩根台股指數期貨推出後,台股指數期貨的交易日趨熱絡,機構法人與一般投資大眾也開始關心期貨契約具有何種特性,其與現貨之間具有何種關係,以及如何利用台股指數期貨來規避風險等問題。因此,本文探討台股指數期貨(futures)與現貨(spot)之相對基差(relative basis)數列之到期日(maturity)與GARCH效應。實證結果發現,摩根台股指數期貨與現貨價格之相對基差同時存在到期日與GARCH效應。此外,本文將此模型應用於動態避險比率的計算,並比較期貨契約的到期日與動態避險比率之關係。
