配對交易策略為一被廣為使用的交易策略，其特性為使用數個關聯性高的資產同時建立多空部位，藉此消除大部分的市場風險，賺取與市場趨勢無關聯性的報酬；本研究欲探討共整合法配對交易策略應用於兩類標的資產上之可行性及其功效:台灣證券交易所掛牌的6檔陸股ETF、以及COMEX黃金期貨與CME日幣期貨之組合。本研究使用之配對交易策略應用於6檔陸股ETF大部分參數設定下可獲得正報酬，獲利性卻不如預期，且共整合性質較佳之配對無法保證其交易績效亦較佳；COMEX黃金期貨及CME日幣期貨雖相對共整合性質不佳，仍以原策略測試可獲得較優秀的績效，此結果顯示共整合法配對交易策略於兩類資產上可行性皆不高，而配對交易策略於黃金、日幣組合上可能仍有其功效，尚須以不同方法進行驗證。 / Pairs trading strategy is one kind of market neutral strategy which take both long and short positions in two or more highly correlated assets. By doing this pairs trading strategy can eliminate market risk and make profits which are not correlated with market trends. This paper aims to figure out if pairs trading strategy work well on China ETFs listed in TWSE and the COMEX gold-CME yen future pair. We use the cointegration approach to test and simulate trading performance on the securities mentioned. The result shows that pairs trading strategy profit on China ETFs under most of the parameters, but the returns are insufficient. Furthermore, good cointegration property in the input periods can’t guarantee better performances in the outputs periods. For COMEX gold future and CME yen future, cointegration property in the input periods are worse than China ETFs, but using the same strategy we find a more profitable outcome. The empirical result indicate that pairs trading strategy might still work on gold and yen, but the cointegration approach is not suitable for these two groups of assets.
