| Popis: | 92 In this study, we consider a portfolio selection problem for long-term investors. Dynamic investment strategy with the continuous-time framework incorporating the minimum guarantees are constructed. Maximizing expected utility of the terminal wealth is employed by investors to trade off profits in good future state against losses incurred in worse states. Follow the previous works of Deelstra et al. (2003), we concentrate on the simplest case of a one-factor Cox-Ingersoll-Ross (CIR) model in formulating the stochastic variation from the interest rate risks. Under the market completeness assumption, the fund growth is modelled under the market neutral valuation and the optimal rules are mapped into the static variational problem of Cox and Huang (1989). In this study, we show that the optimal portfolio is equivalent to a certain mutual fund that can be replicated by the market primary assets |
