Sectoral and thematic funds — March 2026: top-stock concentration as high as 25.3%, five times what a diversified fund holds

Category: Risk Analysis | Published: April 2026 | Universe: 37 sectoral/thematic funds | Data: March 2026 AMFI portfolio disclosures


Summary

Across 37 sectoral and thematic funds analysed for March 2026, the average single-stock concentration in the top holding is 16.1% — meaning nearly one-sixth of the fund sits in one stock. In ICICI Prudential FMCG Fund, a single stock accounts for 25.3% of the entire portfolio.

For context, SEBI's own regulations cap any single stock at 10% of a diversified equity fund's portfolio. Sectoral funds are exempt from this limit — and the data shows exactly how far some fund managers are willing to push that freedom.

Why concentration matters more in sectoral funds

A diversified equity fund — largecap, flexicap, or multicap — spreads risk across sectors and market cycles. If IT underperforms, FMCG or pharma can compensate. Sectoral and thematic funds by definition cannot do this. They are already concentrated by mandate into one theme.

Add single-stock concentration on top of sector concentration, and you have a double-stacking of risk. When ICICI Prudential FMCG Fund puts 25.3% into a single FMCG stock and 66.4% into its top 5, a negative event at one company — a management change, an FSSAI regulatory action, a bad quarterly result — does not just drag the stock. It drags the entire fund.

This is not a theoretical concern. In March 2026, smallcap stocks saw a sharp correction. Funds with high concentration in a few names felt the drawdown disproportionately. The same mechanism applies to sectoral funds: their sector is already their single point of failure, and concentration inside that sector adds a second one.

The sub-themes with the worst concentration

Not all sectoral funds concentrate equally. Technology and FMCG funds show the most extreme single-stock bets, while banking and financial services funds — despite the crowded investible universe — still average above 15% in their top holding.

Technology funds (Kotak, Tata, Franklin, ABSL Digital, HDFC, ICICI Pru, SBI): average top-1 concentration of 16.6%. The reason is structural — Indian listed IT is dominated by TCS, Infosys, and HCL Technologies. Any tech fund must hold at least one of these heavily, and the top three alone often command half the index weight.

Banking and financial services funds face a similar constraint. HDFC Bank alone is approximately 30% of the Nifty Bank index. A banking fund that tracks this universe almost inevitably ends up with HDFC Bank as a dominant position regardless of how many total holdings it carries. This is not necessarily fund manager negligence — it is the structure of the available universe — but the investor still bears the concentration risk.

Defence and PSU funds are the wildcard. HDFC Defence Fund's top 5 holdings account for 62.0% of the entire portfolio across only 22 stocks. This is an extremely thin investible universe combined with high conviction positioning. One negative policy event — a budget cut to defence capex, a procurement delay — lands hard in a fund this concentrated.


What this means for investors

Sectoral and thematic funds are not inherently bad investments. They can deliver exceptional returns when a sector tailwind is strong and sustained. But investors often underestimate a specific type of risk that doesn't show up in NAV history: single-stock concentration risk within the theme.

The standard risk label on a sectoral fund says "Very High Risk." What it doesn't say is that in some funds, this risk is significantly amplified by the fact that nearly one in four rupees you invest is riding on a single company's stock performance. That is a materially different risk profile than a fund that spreads its sector exposure across 50 companies.

The practical implication: before investing in any sectoral or thematic fund, look at two numbers — the top-1 holding percentage and the top-5 holding percentage. If the top-1 exceeds 15%, ask whether you are comfortable with that level of single-stock exposure. If the top-5 exceeds 55%, you are effectively making a bet on 5 companies, not a sector.


Frequently asked questions

Why are sectoral and thematic funds more concentrated than diversified equity funds?

SEBI mandates that sectoral and thematic funds invest a minimum of 80% of their portfolio within their defined sector or theme. This immediately restricts the investible universe. When you add the fact that many Indian sectors are dominated by two or three large companies — IT by TCS and Infosys, banking by HDFC Bank and ICICI Bank, PSUs by NTPC and Power Grid — the concentration is often partly structural, not just a fund manager choice.

Is there a SEBI limit on how much a sectoral fund can hold in a single stock?

SEBI's 10% single-stock cap applies to diversified equity funds. Sectoral and thematic funds are explicitly exempt from this limit. This is why ICICI Prudential FMCG Fund can legally hold 25.3% in one stock — it operates under a different regulatory framework. Investors need to be aware of this exemption when they evaluate sectoral fund risk.

Which type of sectoral fund has the highest single-stock concentration in India?

Based on March 2026 portfolio data across 37 sectoral and thematic funds, FMCG and technology funds show the highest single-stock concentration. ICICI Prudential FMCG Fund leads at 25.3% in its top holding, followed by Kotak Technology Fund at 19.8% and Tata Digital India Fund at 19.6%. Defence and PSU funds, while having fewer holdings overall, show the most concentrated top-5 positions.

How do I interpret the top-5 concentration percentage for a sectoral fund?

The top-5 concentration percentage tells you what fraction of your invested money is concentrated in just five companies. A top-5 of 66.4% — as in ICICI Prudential FMCG Fund — means that roughly two-thirds of your investment tracks the performance of five stocks, not a broad sector. A 10% drop in any one of those five stocks moves the fund's NAV by up to 1.3% on that single event alone, before the rest of the portfolio is considered.

Should I avoid sectoral and thematic funds because of concentration risk?

Not necessarily — but you should size them appropriately. Most financial advisors suggest capping sectoral fund allocation at 10–15% of your total equity portfolio precisely because of this concentration risk. The key is to check the actual portfolio holdings before investing, not just the fund category label. A sectoral fund with 100+ holdings and a top-1 below 10% behaves very differently from one with 20 holdings and a 25% top-1 position.
