本研究主要探討地理距離與期貨避險績效的關係。在近期的研究中,財務學者試著將地理距離與投資者選股策略進行連結,也發現實際的地理距離的確會影響投資者的投資決策。然而,大部分的討論,仍侷限於地理距離與選股決策,很少有學者將研究重點放在地理距離與期貨避險績效關係的探討。本研究的最主要貢獻即是將地理因素引進期貨避險績效中,探討不同地理區域的期貨在避險績效上表現是否會有差異。由於要探討不同地理區域的期貨避險績效,本研究以同時在日本、新加坡以及美國都有期貨交易的日經225指數為研究對象,採用日經225股價指數現貨與大阪證券交易所、新加坡交易所、以及芝加哥商業交易所的日經225股價指數期貨為研究樣本,進行實證分析。我們主要採用誤差修正GJRGARCH模型進行研究。其次,為了討論流動性對避險績效的影響,我們也建立了另一個加入成交量的GJR GARCH模型。此外,我們也引進天真避險法,以及傳統OLS避險法進行不同期貨交易所避險績效的比較。實證結果顯示,芝加哥商業交易所的避險績效表現是最差的,由於芝加哥商業交易所的地理位置相對新加坡交易所以及大阪證券交易所,是距離日經225現貨指數最遠的一個交易所,因此我們發現,地理距離的確會影響期貨避險績效。
Geographic component has attracted significant attention in recent financial research. The objective of this investigation is to shed light on how geographic component and futures hedge performance are related. Futures hedge performances among different distance Exchanges are compared by introducing data from the Nikkei 225 index futures, as listed on the Osaka Securities Exchange (OSE), Singapore International Monetary Exchange (SIMEX) and Chicago Mercantile Exchange (CME). We engage the GJR GARCH with error correction to capture volatility asymmetry. Besides, taking liquidity into consideration, we also construct another GJR GARCH model with trading volume in volatility. Additionally, this study also proposes the naïve hedge and traditional OLS hedge methods to compare among different hedge methods. This study finds that the futures listed on the CME perform worst among the three futures commodities. Since the CME located in the U.S.A. further from Japan than the other two, this investigation provides sufficient evidence that geographic distance influences futures hedge performance.
