Abstract: We study a mathematical model of an insurance company that shares its capital by investing it in both stocks and bonds. The basic tool to describe the evolution of the stock price is the Ornstein-Uhlenbeck process. We construct an estimate for the ruin probability of an insurance company as a function of the initial capital. The distribution of the capital between stocks and bonds is found for which this estimate is minimal.
