The sampling period is from April, 2004 to March, 2005. The coefficient correlation, standard deviation, stock price ratio of the paired stocks are calculated by applying computer programming techniques, through the combination with the pairs trading strategy model.
The purpose is to verify: (1) Paired trading strategies have abnormal returns in Taiwan stock market. (2)When the variable of earning growth rate was implemented into the paired trading model, higher returns can be observed. (3)There are arbitrage opportunities between a pair of stocks which have medium to high correlation coefficient value. (4)No matter bull or bear markets, paired trading strategies can maintain certain returns.
