Selecting funds without falling for marketing

Fund selection should be evidence-based, not marketing-driven. Rolling returns (every 3-year period over 10 years) reveal consistency much better than trailing returns. Compare fund vs category average AND fund vs benchmark. Look at downside (drawdowns), not just upside.

Rolling-return analysis: take all 3-year periods within last 10 years (i.e., monthly windows). What % of windows did the fund beat its benchmark? >60% is good. Average alpha over rolling windows? Standard deviation of those alphas? Funds with high mean alpha and low alpha-volatility are best — consistency matters more than peak performance. Drawdown analysis: max drawdown, recovery time, downside-capture vs upside-capture (a fund with 90% upside-capture and 70% downside-capture beats one with 100/100 over a cycle).

The four red flags before buying: (1) AUM tripled in 12 months — capacity issues incoming. (2) Fund manager changed in last 12 months — style discontinuity risk. (3) Rolling 3-year underperformance vs category for 60%+ of months — consistency issue. (4) Expense ratio materially above category average — cost drag. A fund failing 2+ of these flags is risky regardless of recent returns. Most distributors quote recent returns; sophisticated buyers ask for rolling-return charts and the four-flag check.
