What makes for a good investment? Use the approximate yield formula or a financial calculator to rank the following investments according to their expected returns.
a. Buy a stock for $30 a share, hold it for three years, and then sell it for $60 a share (the stock pays annual dividends of $2 a share).
b. Buy a security for $40, hold it for two years, and then sell it for $100 (current income on this security is zero).
c. Buy a one-year, 5 percent note for $1,000 (assume that the note has a $1,000 par value  and that it will be held to maturity).
