摘要


投資人可利用配對交易策略進行套利,配對交易為假設兩家高度相關公司之股價存在穩定的相對關係,因此藉由同時買進價格偏低的股票以及賣出價格偏高的股票即可獲取價差利潤。 然而一般投資大眾雖知悉配對交易策略,卻不見得可確實執行以獲取超額利潤。本研究利用Freed(1999)提出的理論及劉建國(2005)實證方式,設計交易機械式配對交易策略。並以線性迴歸之方式加以驗證績效穩定度及獲利率。結果發現,相同產業之配對組合股價相關係數相對較高,但配對測試後正報酬卻僅42.5%;另以漲跌幅正相關最高10組為配對組合,正報酬達55%,獲利機率最高。線性迴歸顯示長天數移動平均線獲利較短天數移動平均線穩定,而Z統計檢定顯示相同產業雖然配對正報酬較低但獲利率15%的機率卻高達50%。

When investors use paired arbitrage trading strategies, trading hypothetical pairing two highly correlated to the presence of the secretary of the stock price is relatively stable relationship, so by simultaneously buying undervalued stocks and sell the high price of the stock to get spread profits. However, although the general investing public aware of pairs trading strategy, but it does not necessarily be performed to obtain excess profits.In this study, Freed (1999) proposed the theory and Liu Jianguo (2005) empirical methods, design mechanical trading pairs trading strategies. The results show that the correlation coefficient of the same industry is relatively high, but the positive compensation is only 42.5% after matching test.The other is the positive correlation between the highest group of 10 pairs for the combination of positive returns of 55%, the highest probability of profit.The linear regression shows that the long days moving averages are stable, and the Z statistics show that the same industry has a 50% chance of achieving a 15% yield, although the returns are lower.
