📊 Why Check Mutual Fund Overlap?
Many investors hold 5–10 mutual funds thinking they’re diversified — but 90% of those funds may hold the same 15 Nifty 50 stocks. High overlap means you’re not actually diversified — you own the same stocks multiple times at different expense ratios. This tool checks portfolio overlap so you can trim redundant funds and invest meaningfully.
Step 1 — Select 2 or more funds to compare (up to 5)

Understanding Mutual Fund Overlap in India — Portfolio Concentration & Diversification
India’s active large cap mutual funds are mandated by SEBI to invest 80%+ of their corpus in the top 100 stocks by market cap. This structural constraint means most large cap funds hold nearly identical portfolios — dominated by HDFC Bank, Reliance, ICICI Bank, Infosys, and TCS. Adding a second or third large cap fund doesn’t improve diversification; it just multiplies expense ratios on the same underlying exposure. Overlap analysis helps identify this duplication so you can streamline your portfolio.
✅ Low Overlap (<30%)
Funds are genuinely diversified
Different sectors/market caps
Keep both funds
Examples: Large cap + Small cap; India fund + US fund; Nifty 50 index + Midcap 150 index
⚠️ Medium Overlap (30–60%)
Some redundancy — review needed
Evaluate by expense ratio
Keep the better-performing fund
Examples: Two flexi-cap funds; Large cap + Multi cap; Same category, different AMCs
🚨 High Overlap (>60%)
Near-identical portfolios
Paying double/triple expense ratio
Merge into one fund
Examples: Two large cap funds; Two Nifty 50 index funds; ELSS + Large cap from same AMC

5 Expert Tips to Reduce MF Portfolio Overlap
3-Fund Portfolio Eliminates Most Overlap — Nifty 50 + Midcap 150 + Small Cap 250
The simplest diversified Indian portfolio with near-zero overlap: Nifty 50 Index Fund (top 50 stocks by market cap) + Nifty Midcap 150 Index Fund (ranks 101–250) + Nifty Smallcap 250 Index Fund (ranks 251–500). Combined exposure: top 500 Indian stocks with market-cap weighted allocation and minimal overlap between tiers. Total expense ratio: 0.1–0.3% across all three. Add an International Fund or Nasdaq 100 Fund for global diversification with zero India overlap.
Never Hold More Than 2 Funds From the Same SEBI Category
SEBI has defined 10 equity fund categories — all funds within a category have similar mandates (Large Cap funds must hold 80%+ in top 100 stocks). This structural similarity makes holding 2 large caps = 60–80% overlap guaranteed. Rule: maximum ONE fund per SEBI equity category. Diversification comes from combining different categories: Large Cap + Mid Cap + Small Cap + International + Sector/Thematic.
Index Funds Have Known, Controlled Overlap vs Active Funds
Active fund portfolios change every month — what you see today may differ by 20–30% in 6 months as fund managers reshuffle. Index funds have fixed, rule-based holdings (Nifty 50 = specific 50 stocks). This makes overlap calculation with index funds highly reliable. Mixed portfolio: use index funds as the stable “anchor” with known overlap, and use active funds selectively where manager skill genuinely adds value (typically Mid/Small cap categories where markets are less efficient).
Check Overlap After Every Portfolio Review (At Least Annually)
Mutual fund portfolios drift over time — a Small Cap fund that had low overlap with your Large Cap fund 3 years ago may have migrated to Mid/Large stocks as small caps grew. SEBI reclassification events (which happened in 2017 and again in 2023) dramatically changed fund categories and mandates. Run overlap check annually, especially after large market moves where fund managers may have repositioned. This tool helps identify new concentration before it affects your risk profile.
High Overlap + High Expense = Exit Signal — Prefer Lower Expense Fund
If two funds have 70%+ overlap, you should ideally hold only one. Choose based on: lower expense ratio (direct plan vs regular plan — difference is 0.5–1%/year, massive over 20 years); better 10-year SIP return track record; fund house reputation and fund manager stability; lower fund size for small/mid caps (large AUM hurts performance). When exiting an overlap fund with gains: check LTCG (12.5% on gains above ₹1.25L). Wait for 1-year mark to qualify for LTCG vs STCG (20%).
