Abstract: Abstract We consider a market consisting of a stock St and a bond Bt governed by the following equations: 13.1 $$d{S_t} = a(t,{S_t}){S_t}dt + {\sigma _t}{S_t}d{W_t} $$ and 13.2 $${\text{d}}{{\text{B}}_{\text{t}}}{\text{ = }}{{\text{r}}_{\text{t}}}{{\text{B}}_{\text{t}}}{\text{dt,}} {{\text{B}}_{\text{0}}}{\text{ = 1}}$$ where Wt is a Brownian motion, S0 is a given random variable independent of W, rt is a bounded, non-negative, progressively measurable interest rate process.
