Quick Answer
These five indicators can help you understand a fund’s return, volatility and relationship with its benchmark, but none can tell you on its own whether to invest. Use a consistent period, a relevant benchmark and peer-group comparisons, then consider fees, objectives and your risk capacity.
Correct Interpretation and Practical Use
Start with the Core Point
Alpha is performance relative to a selected benchmark, not guaranteed manager skill. Beta measures sensitivity to market movements, not a promise that future gains or losses will occur in a fixed multiple. R-squared shows how much of the fund’s past variation is explained by its benchmark. Standard deviation measures the dispersion of historical returns, while the Sharpe ratio relates excess return to volatility. Every figure depends on the period, data frequency, benchmark and market environment.
How to Use This
- Check that the fund objective and benchmark genuinely match.
- Compare funds in the same category, currency and period.
- Also review fees, holdings, drawdowns, manager changes and investment limits.
