Taiwan government bonds have always been the important part of Taiwan’s life insurance industry’s long-term investment assets allocation. But in recent years, the five major life insurances continue to reduce their positions. According to the latest statistics of TCB, the five life insurance holding ratios have fallen to a record low of 9.07% in March. Taiwan government bond’s yield and volatility continue falling, and according to the government's debt-raising conservative, government bond supply has plummeted. The long-term trading strategy has not been able to provide sufficient profit. This paper hopes to improve the performance of the company's original 14-day weighted moving average (WMA) breakthrough strategy trading model. It is intended to use the "Taiwan stock change", "US federal funds rate" and "US ten-year period" respectively. Multivariate regression prediction model and time series prediction model established by important factors affecting Taiwan bond yields, such as the “public debt yield” and “Taiwan overnight interest rate”, which produce the predicted value of Taiwan’s 10-year public debt and use it to replace market prices. Calculate trading signals to reduce the interference of market noise and achieve the goal of improving overall compensation. This paper hopes to improve the performance of the company's original 14-day weighted moving average (WMA) breakthrough strategy trading model. Trying to use "Taiwan stock change", "US federal funds rate" ,"US ten-year period" ,“public debt yield” and “Taiwan overnight interest rate” establish multiple regression prediction model and time series prediction model. And produce the predicted value of Taiwan’s 10-year public debt and use it to replace market prices. Calculate trading signals to reduce the interference of market noise and improve profitibility. The empirical results show that in the backtesting from 2008 to 2017, the WMA breakthrough strategy performance of the time series prediction model is the best, and the WMA breakthrough strategy performance of the multiple regression prediction model is second, which is better than the original 14 days. The WMA breakthrough strategy; and the same results in the extra-sample backtest from 2018 to 2019, shows that after the addition of quantitative analysis, the simple technical indicator trading strategy can significantly improve the performance.
