Average Annual Return
Average Annual Return (AAR) refers to the average yearly return on an investment over a specified period. By calculating the mean return for each year within the period, AAR reflects the long-term performance of the investment. AAR is commonly used to evaluate the historical performance of investment funds, stocks, and other financial assets, helping investors compare and select different investment products.
Key characteristics include:
- Time Period: AAR typically calculates the average return over multiple years, reflecting long-term investment performance.
- Historical Performance Evaluation: Used to assess past investment performance and provide reference for future investment decisions.
- Comparison Tool: Helps investors compare historical returns of different investment products and choose suitable investments.
- Simplicity: The calculation method is relatively simple, easy to understand, and apply.
The average annual return (AAR) is a percentage used when reporting the historical return, such as the three-, five-, and 10-year average returns of a mutual fund. The average annual return is stated net of a fund's operating expense ratio. Additionally, it does not include sales charges, if applicable, or portfolio transaction brokerage commissions.In its simplest terms, the average annual return (AAR) measures the money made or lost by a mutual fund over a given period. Investors considering a mutual fund investment will often review the AAR and compare it with other similar mutual funds as part of their mutual fund investment strategy.
Average Annual Return (AAR)
Average Annual Return (AAR) refers to the average annual return of an investment over a specific period. It reflects the long-term performance of an investment by calculating the average of the annual returns over a given period. AAR is commonly used to evaluate the historical performance of investment funds, stocks, and other financial assets, helping investors compare and select different investment products.
Origin
The concept of Average Annual Return originated in the early development of financial markets. As investment products diversified and investors' focus on long-term returns increased, AAR became an important metric for evaluating investment performance. Particularly in the mid-20th century, with the popularization of mutual funds and other collective investment tools, AAR was widely used in fund performance reports.
Categories and Characteristics
The main characteristics of Average Annual Return include:
- Time Period: AAR typically calculates the average return over multiple years, reflecting long-term investment performance.
- Historical Performance Evaluation: Used to assess past investment performance and provide a reference for future investment decisions.

Specific Cases
Case 1: Suppose an investment fund had annual returns of 10%, 8%, 12%, 6%, and 14% over the past five years. The calculation of the Average Annual Return is as follows:
AAR = (10% + 8% + 12% + 6% + 14%) / 5 = 10%
Case 2: A stock had annual returns of 5%, -2%, and 9% over the past three years. The calculation of the Average Annual Return is as follows:
AAR = (5% + (-2%) + 9%) / 3 = 4%
Common Questions
1. Can Average Annual Return predict future returns?
AAR mainly reflects past performance and cannot directly predict future returns. Investors should use other analytical tools and market information for comprehensive judgment.
2. Why do different investment products have significant differences in AAR?
Different investment products have varying risks, market environments, and management strategies, leading to differences in AAR. Investors should choose suitable products based on their risk tolerance and investment goals.
