What is Mutual Fund Overlap?
When two or more of your mutual funds hold the same underlying stocks, that's overlap. You're not getting extra diversification — you're just paying extra expense ratios.
Why Overlap is a Problem
Example: You hold:
- Mirae Asset Large Cap Fund
- Axis Bluechip Fund
- HDFC Top 100 Fund
All three funds have these in their top 5:
- HDFC Bank (~9%)
- Reliance Industries (~8%)
- ICICI Bank (~7%)
- Infosys (~6%)
You think you hold 3 funds. You actually hold 1 fund's exposure, 3 times.
Common High-Overlap Fund Pairs
| Fund 1 | Fund 2 | Overlap |
|--------|--------|---------|
| Mirae Asset Large Cap | Axis Bluechip | ~70% |
| HDFC Top 100 | ICICI Pru Bluechip | ~75% |
| Any two Nifty 50 index funds | Each other | ~100% |
| Parag Parikh Flexi Cap | Motilal Oswal Flexi Cap | ~45% |
How to Fix Overlap
- Keep only one fund per category (one large-cap, one mid-cap, etc.)
- Replace multiple large-cap active funds with one Nifty 50 index fund
- For diversification, add asset class diversity — not more equity funds
