Understanding Return Calculations

Different methods of calculating investment returns can yield varying results. The most appropriate method depends on your specific situation and analysis needs.

Arithmetic Mean vs. Geometric Mean

The arithmetic mean simply averages the returns over each period, while the geometric mean (CAGR) accounts for compounding effects. For volatile returns, the arithmetic mean will always be higher than the geometric mean.

  • Arithmetic Mean: Better for estimating expected future performance over a single period.
  • Geometric Mean (CAGR): Better for measuring actual historical performance.
Money-Weighted vs. Time-Weighted Returns

These measures differ in how they account for the timing and amount of cash flows:

  • Money-Weighted Return (IRR): Accounts for both the timing and size of cash flows. Best for measuring the return on a specific investor's portfolio.
  • Time-Weighted Return: Eliminates the impact of cash flows, making it ideal for evaluating investment manager performance regardless of when investors add or withdraw money.
When to Use Each Method
  • Use Time-Weighted Return when evaluating investment managers or strategies.
  • Use Money-Weighted Return when analyzing the performance of your personal portfolio.
  • Use CAGR when comparing investments over multiple periods.
  • Use Arithmetic Mean when making future projections for a single time period.
