(a) (6 points) There are two companies. The first one is a highly uncertain startup gaming company. The only chance for the company to succeed is that the market tanks so that people have nothing to do and start playing games. The second one is a boring oil company with stable customers. The only uncertainy is that if the economy is not good, they may lose a couple clients. Based on CAPM, the second one is safer than the first one.
