1. 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% note for $1,000 (assume that the note has a $1,000 par value and that it will be held to maturity).
