Scenario: Diversification
Morris is considering investing $10,000 in a sunglass company or a rain poncho
company. If it is a rainy year and he invests only in the sunglass company, he will lose
$5,000. However, if it is a rainy year and he invests only in the rain poncho company,
he will earn $10,000. If it is a sunny year and he invests only in the sunglass company,
he will earn $10,000; if he invests only in the rain poncho company, he will lose $5,000
in a sunny year. There is a 50% chance of a sunny year and a 50% chance of a rainy
year.
