Return – The increase in an investment’s value during a year expressed as a percentage of the investment’s value at the beginning of the year. For example, an investment worth $100 at the beginning of the year and $110 at the end of the year has increased in value by $10, so the investment’s return for the year is 10 percent ($10 / $100 = .10 = 10%).
