Finally, we apply the factor analysis of the interest rate risk factors that change the yield curve of bond. Based on the comparison of the static models and stochastic models, we bring forward a dynamic stochastic risk management model of interest rate. In addition to this, we conduct an empirical examination of the management of risk immunized bond portfolios.
