What is mutual fund portfolio overlap?
Mutual fund portfolio overlap means two or more of your funds hold the same underlying stocks. For example, if you own both a Nifty 50 index fund and a large-cap flexi fund, they likely hold HDFC Bank, Reliance, and TCS in common — reducing your actual diversification despite owning multiple funds.
Why is mutual fund overlap bad for your portfolio?
High overlap means you are paying management fees on multiple funds that effectively do the same thing. It also increases concentration risk — if the overlapping stocks fall, all your funds drop together, giving a false sense of diversification.
What is an acceptable level of overlap?
- Below 30% — Generally acceptable, funds serve different purposes
- 30–50% — Significant duplication, consider consolidating
- Above 50% — These funds are doing the same job; keep only one
