Understanding Average Return š
Definition:
The average return is the simple mathematical average of a series of returns generated over a specified period of time. It’s calculated by summing up all the returns and dividing that sum by the total number of returns. Think of it as your financial āslice of cakeā where each layer is a return and you just want to know how tasty each layer is, on average!
Comparison: Average Return vs Annualized Return
| Concept | Average Return | Annualized Return |
|---|---|---|
| Calculation | Simple average of returns over a period | Compounded return over multiple periods |
| Compounding | Ignores compounding of returns | Accounts for compounding, giving a more realistic view |
| Time horizon | Fixed period, can be any length | Usually expressed on an annual basis |
| Usefulness | Easier to calculate for quick insights | Better for long-term investment performance assessments |
Examples
-
Calculating Average Return:
Suppose your investments returned:
5%, 10%, 15%, and -3%.
Average Return Calculation:
\[ \text{Average Return} = \frac{(5 + 10 + 15 - 3)}{4} = \frac{27}{4} = 6.75% \] -
Geometric Average:
Geometric average, useful when dealing with compounded returns, would look at this same series but give more weight to lower-performing returns:
Geometric Average Calculation:
\[ \text{Geometric Average} = \left( (1 + 0.05) \times (1 + 0.10) \times (1 + 0.15) \times (1 - 0.03) \right)^{1/4} - 1 \]
Related Terms
- Geometric Average: A method of averaging that takes into account compounding, hence is typically lower than the average return if returns vary.
- Compound Annual Growth Rate (CAGR): Represents the average annual growth rate over a specified time period while considering the effect of compounding.
