For each of the following statements, state whether it is true or false. If false, how could the statement be modified to render it true? (a) Preferred stock is riskier than corporate bonds, due to the fact that owners of preferred stock can force the firm into bankruptcy if the firm fails to make promised dividend payments. (b) A speculator who buys a derivatives contract for an agri- cultural product, such as coffee, is a risk-taker, while the issuer of the contract, who owns the agricultural product (coffee) wishes to avoid risk. (c) Fixed income securities may be valuable to retirees who are looking for a predictable source of income, but they tend to carry both a lower rate of return and greater risk than corporate stock.
