With a bank account and a risky stock, both of which are affected by Cox-Ingersoll-Ross’s interest rates, we treat two “down-side risk” minimization problems of the large deviation probability for long-term investment. Explicit solutions of the problems are given by solving the associated risk-sensitive portfolio optimization problems.
