Based on Kelly (1956). You currently have \$100. Each week you can invest any amount of money you currently have in a risky investment. With probability 0.4, the amount you invest is tripled (e.g., if you invest \$100, you increase your asset position by \$300), and, with probability 0.6, the amount you invest is lost. Consider the following investment strategies:

■ Each week, invest 10% of your money.

■ Each week, invest 30% of your money.

■ Each week, invest 50% of your money.

Use @RISK to simulate 100 weeks of each strategy 1000 times. Which strategy appears to be best in terms of the maximum growth rate? (In general, if you can multiply your investment by M with probability p and lose your investment with probability q 1 p, you should invest a fraction [p(M – 1) – q]/(M – 1) of your money each week. This strategy maximizes the expected growth rate of your fortune and is known as the Kelly criterion.)
