在期貨交易的發展上,農產品為早期即上市交易之期貨商品,近年來因環境氣候變化,再生能源政策影響以及金融重大事件之影響,使農產品價格波動快速劇烈,加上大陸期貨交易市場發展迅速,成為世界上第二大農產品期貨交易市場,使投資人在交易農產品期貨上除了芝加哥期貨交易所之外,增添另一個選項,本文目的在探討跨市場相同商品是否存在套利避險之效益,同時研究期貨間避險的最適比率,研究樣本取自美國芝加哥交易所和大連期貨交易所之玉米期貨日資料,期間為2003年1月28日至2017年12月22日,合計交易筆數為2881筆,以及芝加哥交易所和大連期貨交易所之大豆期貨日資料,期間為2004年9月22日至2017年12月22日,合計交易筆數為2650筆,檢定模型採用單根檢定與ARCH檢定進行測檢,最後採用GARCH模型與DCC-GARCH模型做實證分析。 本文利用芝加哥期貨交易所之大豆期貨與玉米期貨,和大連期貨交易所之大豆期貨與玉米期貨進行檢定分析,因兩者皆為交易活絡之市場,預期商品之流動性與價格波動度皆適合展開配對套利交易,且上述兩項商品交易結算合約月份相似,皆採用實物交割方式,可避免因交割方式不同,造成強制平倉事宜,另美國農產品期貨市場因自然人交易居多,所以價格波動劇烈,風險較大,大陸農產品期貨交易市場以法人機構參與居多,價格波動較平緩,因此投資人可透過此特性商品進行避險策略,以提高交易獲利並降低投資風險。
