Mutual Fund Overlap: Why Your 5 Funds Are Really One

Owning many funds isn't diversification — if they hold the same stocks, you have one fat fund pretending to be five.

Two large-cap funds can overlap 60-80% because both fish from the same AMFI top-100 list.

Funds disclose full portfolios monthly by the 10th; free overlap tools turn that into a single percentage.

Treat anything above ~50% common holdings as a red flag — it adds cost and admin, not safety.

A clean portfolio rarely needs more than 3-5 funds spanning different caps, styles and asset classes.
