Abstract
Dynamic fund protection provides a guarantee that the account value of the investor never drops below a barrier over the investment period. In order to reduce the downside risk taken by vendors, Han, et al. (2016) proposed a chained dynamic fund protection (CDFP), whose protection is activated only if the value of basic fund reaches a predefined upper protection line. Motivated by them, we consider a new CDFP plan under a stochastic interest rate environment. The explicit pricing formula for a CDFP is obtained when the protection lines are proportional to a zero-coupon bond. Furthermore, the authors present some numerical results for the value of CDFP at time 0 to show how the model parameters impact the value of CDFP.
