Definition

A Sector Fund is a SEBI-defined equity mutual fund category under the Categorisation and Rationalisation Circular (October 2017). The category requires that at least 80% of total assets be invested in equity and equity-related instruments of a specific sector. The sector is defined by uniform industry classification — typically NSE sectoral indices or BSE sectoral indices serve as the benchmark universe. Common sectors include Banking and Financial Services, Information Technology, Pharmaceuticals, FMCG, Infrastructure, and Energy. Unlike Thematic Funds, Sector Funds are restricted to a single industry classification. The high concentration mandate means these funds carry the highest concentration risk among SEBI equity categories. Each AMC may operate multiple Sector Funds — one per sector — subject to distinct scheme documentation per SEBI norms.

How the category is defined

SEBI's Categorisation Circular specifies:

  • Minimum 80% of total assets in equity and equity-related instruments of the designated sector
  • Remaining 20% at manager discretion per SID — may include other sectors or debt
  • Sector definition: Aligned to NSE/BSE sectoral indices or AMFI industry classification
  • No one-per-AMC restriction for sector funds — AMCs may run multiple sector schemes in distinct sectors

SEBI does not cap how many sector funds an AMC may operate, unlike most other categories where the rule is one scheme per category. This allows fund houses to offer distinct Banking, IT, Pharma, and Infrastructure sector funds simultaneously. AMFI's bi-annual list tracks registered sector fund schemes and their designated sectors.

Tax treatment

Sector Funds maintain ≥80% in equity and are classified as equity-oriented funds for income tax purposes. Tax rules as of FY2024–25:

  • Short-term capital gains (held <12 months): 20%
  • Long-term capital gains (held ≥12 months): 12.5% on gains exceeding ₹1.25 lakh per year

Tax treatment is identical to diversified equity funds. Investors should note that while tax treatment is equivalent to large-cap or flexi-cap funds, the risk profile is not — sector concentration creates higher volatility and drawdown potential than diversified equity categories.

What investors should look at

Relevant factual parameters:

  • Sector cycle position: Sectors have distinct business cycles (IT tied to global tech capex, Pharma to USFDA approvals and domestic pricing). Review where the sector is in its earnings cycle — not just the fund's past NAV trajectory.
  • Concentration within sector: A "Banking" sector fund may hold 8–15 stocks; the top 5 often account for 60–70% of the portfolio. Stock-level concentration compounds sector concentration.
  • Benchmark alignment: Compare fund allocation against the sector index. Active share vs the Nifty Bank or Nifty IT index indicates whether the fund is adding selection value or tracking the index with higher fees.
  • Regulatory risk: Sectors like Pharma (USFDA), Banking (RBI regulations), and Energy (government price controls) carry policy risk that diversified funds can partially insulate against.
  • Drawdown history: Sector funds have exhibited 40–70% peak-to-trough drawdowns in sector-specific downturns. Maximum drawdown in SID-disclosed rolling periods is a key reference.

Worked example

A Pharma Sector Fund with ₹2,500 Cr AUM holds 85% in pharmaceutical companies: Sun Pharma, Dr. Reddy's, Cipla, Divi's Labs, and 10 smaller pharma companies. In 2015–2016, when USFDA import alerts hit several Indian pharma manufacturers, the Nifty Pharma index fell ~35% from peak, while the Nifty 50 fell only ~20%. Investors in a Pharma Sector Fund during this period experienced losses roughly 75% worse than the broad market. Conversely, during COVID-era demand for pharmaceutical products in 2020–2021, the Nifty Pharma index rose ~90% vs Nifty 50's ~80% recovery, illustrating the sector's amplified cyclicality. AMFI factsheet data for sector funds consistently shows higher standard deviation than diversified equity categories.
