我們將two-step approach cointegration 和double exponential smoothing prediction (DESP) model 以及nonparametric tolerance limits 應用在配對交易。一開始我們將two-step approach cointegration 作為配對的股票是否具有stationary 性質的準則，接著使用DESP 決定適當的股票比例，最終以nonparametric tolerance limits 計算歷史資料，得到上、下限作為進、出場的信號。在實證研究中，我們將此策略應用在台灣市場，接著分析表現，並深入探討這個策略。;We propose a pairs trading strategy using the two-step cointegration, the double exponential smoothing prediction (DESP) model, and the nonparametric tolerance limits. The first part is to use two-step cointegration test to find out stocks with stationary nature and apply the DESP in order to obtain the appropriate stock ratio. Finally, based on the historical data, the appropriate upper and lower bounds as the entry and exit signals can be calculated by using nonparametric tolerance limits. In empirical studies, we apply the proposed strategy to the Taiwan stock market, analyze the performance, and provide some further discussion on the trading strategy.
