Investment performance is an investment’s level of growth over time. This is often referred to as the investment's returns and is measured by the percentage change of the investment's value over time.
What is investment performance?
For example, if a stock is priced at $100 today and increases to $110 a year from now, the investment's return is 10% over the one-year period. Investments are often compared with their past performance, but they can also be compared with a benchmark’s performance.
