Abstract: We consider a risk process generalizing the classical Cramér–Lundberg process. The feature of the process is that its price function depends on the current reserve of an insurance company as well as on its portfolio consisting of a riskless bond and a finite number of risky assets, modeled by geometric Brownian motions. We obtain an analogue of the classical exponential estimate for the ruin probability in this case. It turns out that the estimate for the model with investments is better than the corresponding estimate for the classical model without investments.
