Let me share a portfolio review I conducted last month that perfectly illustrates the problem SEBI is now fixing:
Investor: “Amit, I’ve carefully diversified across five different equity funds to spread my risk. I feel quite secure.”
Me: “Let’s check the actual overlap. You hold three thematic funds, Technology, Digital India, and Innovation. Let me pull up their portfolios…”
After analysis
Me: “Your three ‘different’ funds share 18 of their top 20 holdings. Infosys, TCS, HCL Tech, Wipro, Tech Mahindra, same stocks, similar weights. You’re paying three separate expense ratios for essentially the same portfolio.”
Investor: Shocked “But they have different names! How is this possible?”
This conversation – which I’ve had dozens of times with different investors, captures exactly what SEBI’s new 50% portfolio overlap cap aims to eliminate: the illusion of diversification.
On February 26, 2026, SEBI issued a landmark circular introducing strict portfolio overlap limits that will fundamentally change how equity mutual funds operate in India. If you hold multiple equity funds, especially sectoral, thematic, value, or contra schemes, this regulation will directly impact your portfolio.
Let me walk you through what’s changing, why it matters, and what you should do about it.
Important disclaimer: This article is purely educational. Portfolio overlap rules are subject to SEBI regulations and AMC implementation. Always consult an AMFI-registered distributor or SEBI-registered investment advisor for personalized portfolio review and guidance specific to your financial situation.
What Is Portfolio Overlap – And Why Should You Care?
The simple explanation:
Portfolio overlap measures how many common stocks (and in what proportions) two mutual fund schemes hold.
A practical example:
Fund A: Reliance (8%), HDFC Bank (7%), Infosys (6%), ICICI Bank (5%), TCS (5%)...
Fund B: Reliance (9%), HDFC Bank (6%), Infosys (7%), ICICI Bank (4%), TCS (6%)...
These two funds have significant overlap – they’re investing in the same companies with similar allocations.
Why this matters to you:
- Problem #1: False Diversification
You think: “I’m spreading risk.”
Reality: 70-80% same stocks = concentrated exposure + multiple fees. - Problem #2: Magnified Risk
Common holdings crash → ALL funds decline together. - Problem #3: Paying for Nothing
Active fees for cloned portfolios? - Problem #4: Closet Indexing
“Active” funds mimicking each other or indices.
SEBI’s goal: Force genuinely different strategies.
The New 50% Overlap Rule: What Exactly Changed?
SEBI’s February 26, 2026 circular (No. SEBI/HO/24/13/15(2)2026-IMD-RAC4/I/5764/2026) introduced specific limits:
Rule #1: Sectoral and Thematic Equity Schemes
Restriction: No sectoral/thematic scheme >50% overlap with:
- Other sectoral/thematic (same AMC)
- Other equity categories (flexi/multi/mid/small-cap, focused, dividend yield, value/contra) (same AMC)
Important exception:
Large-cap funds can exceed 50% overlap with sectoral/thematic (natural, since all draw from top 100 stocks), but sectoral/thematic cannot exceed 50% with each other or other non-large-cap equity.
Why: Large-cap mandates 80% top 100 stocks – inevitable overlap.
Practical impact: HDFC “Technology Fund” + “Digital India Fund” must have 50% DIFFERENT stocks.
Rule #2: Value and Contra Funds
- New: AMCs can offer BOTH (previously often one only)
- Condition: ≤50% overlap between value + contra (same AMC)
How Portfolio Overlap Is Calculated
Methodology (simplified):
- Match at ISIN level
- Take LOWER weight for common stocks
- Sum = overlap %
Example:
| Stock | Fund A % | Fund B % | Overlap |
|---|---|---|---|
| Reliance | 8% | 9% | 8% |
| HDFC Bank | 7% | 6% | 6% |
| Infosys | 6% | 7% | 6% |
| ICICI Bank | 5% | 4% | 4% |
| Total | 24% |
Frequency: Quarterly (daily average), prevents gaming.
The Transparency Revolution: Monthly Disclosures
Game-changer: AMCs must publish category-wise overlap monthly on websites:
- Equity vs equity
- Debt vs debt
- Hybrid vs hybrid
Before: Manual factsheet analysis.
After: Official data → instant decisions.
Use it to: Audit portfolio, compare before buying, hold AMCs accountable.
Compliance Timeline: 3-Year Glide Path
New schemes: Immediate compliance.
Existing >50% schemes:
| Year | Progress | Ex: 80% → |
|---|---|---|
| 1 | -35% excess | 69.5% |
| 2 | -35% excess | 59% |
| 3 | -30% excess | ≤50% |
Deadline: April 1, 2029.
Non-compliant: Mandatory merger.
Industry impact: 51 schemes, ₹76,000cr AUM need realignment.thehindubusinessline
Why Investors Win
- Real diversification (not illusion)
- Active fee justification
- Cleaner lineups (1000+ → 600-700 schemes)
- Monthly transparency
- Better risk management
Challenges & Responses
- Transition volatility: Stay patient (3-year path).
- Mergers/tax: Monitor + switch early if needed.
- Natural overlap: OK up to 50% (quality stocks).
- Gaming: Quarterly averages mitigate.
What You Should Do NOW (6 Steps)
- Audit portfolio (Value Research/Morningstar tools)
- ✅ <40%: Good
- ⚠️ 40-60%: Review
- ❌ >60%: Consolidate
- Monitor AMC sites (monthly overlap matrix)
- Review thematic holdings (51 schemes at risk)
- Check value/contra (if both held)
- Ideal structure: 1 large/flexi + 1 mid + 1 small (+1 thematic conviction)
- Consult before changes (loads/tax: STCG slab <1yr, LTCG 12.5% >1yr)
Real Investor Scenarios
Scenario 1: Thematic Collector (Tech/Digital/Innovation/Consumption)
78% overlap → Reconstruction/mergers → Consolidate now.
Scenario 2: Value + Contra (55% overlap)
Minor adjustment → Monitor.
Scenario 3: Multi-AMC diversified
Minimal impact → Continue.
Common Questions
- Performance hit? Short-term possible, long-term better.
- Index funds? Excluded (intentional 100% overlap).
- Cross-AMC? No limit (your choice).
- Wait 3 years? No – act now for control.
Bigger Picture: Industry Evolution
- Quality > quantity
- Trust via transparency
- True active management
- Global standards alignment
Final Perspective: True Diversification Wins
Most investors have too many duplicate funds. SEBI fixes this at source.
Your wins: Real diversification, justified fees, resilience, easy decisions.
