Compounded Reality
Geometric return best represents multi-period wealth growth under compounding.
Volatility Interpretation
Return dispersion affects realized growth even when arithmetic averages look attractive.
Benchmark Comparison
Consistent-period analysis improves fairness of strategy comparisons.
Net-of-Cost Perspective
Fees and taxes are essential for investor-level performance realism.
Decision Context
Average metrics should be combined with risk and drawdown analysis.
Frequently Asked Questions
What is arithmetic vs geometric return?+
Arithmetic is simple mean; geometric reflects compounding and is usually lower when volatility exists.
Which average should I use?+
Use geometric average for long-term growth interpretation and arithmetic for short-run expectation context.
Why does volatility matter?+
Volatility drag reduces compounded growth relative to simple average.
Can negative years affect averages strongly?+
Yes. Losses can disproportionately reduce compounded outcomes.
Is average return a guarantee?+
No. It summarizes past or assumed data and does not guarantee future performance.
Should fees be included?+
Yes. Use net returns for realistic investor outcomes.
Can this compare funds?+
Yes, when measurement windows and assumptions are consistent.
How many periods are enough?+
Longer horizons usually provide more stable perspective but still include regime risk.
Can inflation-adjusted return be modeled?+
Yes by converting nominal returns to real-return assumptions.
How often should averages be updated?+
Update with each new period to maintain current performance context.
