Sectoral and Thematic Mutual Funds: Concentrated Bets on Specific Industries

What is a sectoral fund?

A sectoral mutual fund invests at least 80% of its assets in equities of companies belonging to a single sector. The sector is named in the scheme's mandate and in its Scheme Information Document. Common sectoral fund categories in India include:

• Banking and Financial Services — banks, NBFCs, insurance, asset managers, capital markets companies.
• Information Technology (IT) — IT services, product companies, BPO, IT-enabled services.
• Pharmaceuticals and Healthcare — pharma manufacturers, hospital chains, diagnostic chains, healthcare providers.
• FMCG (Fast-Moving Consumer Goods) — packaged food, personal care, household products, beverages.
• Auto and Auto Ancillaries — vehicle manufacturers, component suppliers, tyre makers, batteries.
• Energy — oil and gas, refineries, power utilities, renewables.

The defining characteristic is single-sector concentration. A banking sectoral fund holds nothing but banking and financial stocks. When the banking sector outperforms the broader market, the fund typically outperforms diversified equity funds. When the banking sector underperforms — for example during the NPA cycle of 2014-2020 — the fund underperforms diversified equity funds.

What is a thematic fund?

A thematic mutual fund invests across multiple sectors that share a common theme. The theme is broader than a single sector and is typically tied to a long-term economic narrative or trend. Common themes seen in the Indian mutual fund industry include:

• Manufacturing — capital goods, autos, defence, chemicals, electronics manufacturing — companies expected to benefit from production-linked incentive schemes and Make in India.
• Consumption — FMCG, retail, autos, durables, paints, jewellery — companies tied to rising household spending.
• Infrastructure — capital goods, cement, construction, power, transmission — companies tied to public and private capex.
• ESG (Environmental, Social, Governance) — companies meeting defined ESG screening criteria across sectors.
• Digital / Technology — IT services, internet, payments, e-commerce, telecom.

Thematic funds are less concentrated than sectoral funds because the theme can span 3-7 sectors. But they still carry materially more concentration risk than a diversified equity fund. A manufacturing thematic fund holding capital goods, autos, and chemicals will underperform during a cyclical downturn in those industries even if banking, IT, and FMCG perform well.

How sectoral and thematic funds differ from diversified funds

A diversified equity fund — large cap, multi cap, flexi cap, or ELSS — holds companies across many sectors. The fund manager chooses sector weights based on bottom-up stock selection or top-down macro views, but no single sector typically exceeds 25-30% of the portfolio. This diversification smooths returns because at any given time, some sectors are doing well and others are doing poorly.

Sectoral and thematic funds deliberately throw away this smoothing. The investor accepts higher volatility in exchange for the potential of concentrated upside if the chosen sector or theme outperforms. The trade-off can work — but it also means extended periods of underperformance if the sector enters a down cycle.

Pros: when concentration works

• Higher upside in a sector up-cycle: when a sector enters a multi-year up-cycle, sectoral funds historically captured most of the upside without being diluted by underperforming sectors elsewhere in the diversified universe.
• Easier to understand: a banking sector fund is easier for a retail investor to mentally track than a multi-sector flexi cap fund. The investor follows a smaller set of companies and macro variables.
• Targeted thematic expression: if an investor has a strong conviction about a long-term economic narrative (manufacturing, digitalisation, energy transition), thematic funds let them express that view through a diversified basket of relevant companies rather than picking individual stocks.
• Standalone tax-efficient vehicle: taxed as equity, like all equity-oriented funds.

Cons: when concentration hurts

• Sector cycles can last 5+ years: the Indian banking sector underperformed the broader market through much of 2014-2020 due to NPA stress. Investors holding only banking funds during that period experienced sustained underperformance, often well beyond their original investment horizon.
• Higher volatility: peak-to-trough drawdowns of sectoral funds typically exceeded those of diversified funds during sector-specific stress events.
• Timing required: sectoral fund returns are highly dependent on entry and exit timing. Capturing the full up-cycle while avoiding the down-cycle requires either luck or skill that most investors do not possess.
• Tax inefficiency on rotation: investors who try to rotate between sectoral funds — exiting the IT fund to buy the banking fund, for example — incur capital gains tax on every switch. Over multiple rotations, taxation alone can consume a meaningful portion of returns.
• Behavioural pitfall: retail investors historically tended to enter sectoral funds after a multi-year up-cycle (chasing recent winners) and exit after a multi-year down-cycle (capitulating at the bottom). This pattern has been documented across many sectors.

Historical sector cycles in India

Indian sector cycles have been long and pronounced. A few illustrative episodes (educational context, past tense):

IT during 1999-2000: the dot-com euphoria

Indian IT services companies — Infosys, Wipro, Satyam, NIIT — saw extraordinary share-price rises during the late 1990s and early 2000s as the global dot-com boom amplified demand for IT services. Investors who entered IT-focused mutual funds in 1996-1998 experienced multi-fold gains. Those who entered in late 1999 and early 2000 — as the headlines reached peak intensity — frequently experienced steep losses when the bubble unwound through 2001-2002.

Infrastructure during 2003-2007: the capex super-cycle

Indian infrastructure companies — capital goods, construction, power, cement — were among the strongest performers between 2003 and 2007 as a domestic capex cycle gathered pace. Infrastructure thematic funds attracted heavy retail inflows toward the end of this cycle. The 2008 global financial crisis ended the cycle abruptly. Many infrastructure funds underperformed the broader market for several years afterwards as the capex cycle did not recover meaningfully until well into the 2020s.

Banking during 2014-2018, then NPA pain through 2020

Indian banks initially outperformed the broader market through 2014-early 2018 as private-sector banks expanded retail lending. The 2018-2019 NPA cycle and the IL&FS-DHFL fallout reversed this trend. Banking sectoral funds underperformed the broader market for an extended period, with PSU bank exposure particularly painful. Recovery began in late 2020 as the credit cycle stabilised.

IT during 2020-2021: the pandemic tailwind

Indian IT services experienced a sharp re-rating in 2020-2021 as global enterprises accelerated digitalisation during COVID-19. IT sectoral funds outperformed for a sustained period. The subsequent global tech down-cycle in 2022-2023 reversed part of these gains as enterprise IT spending tightened.

Where thematic funds historically clustered

Theme launches by Indian AMCs have historically clustered around government policy announcements and macro narratives:

• Manufacturing themes proliferated after the launch of Make in India and the Production-Linked Incentive (PLI) schemes.
• ESG funds launched in 2019-2021 as global ESG capital flows became a market narrative.
• Digital / Technology themes attracted attention during the 2020-2021 pandemic-driven digitalisation wave.
• Consumption themes have been launched periodically, tied to rising per-capita income narratives.

A cautionary observation: many themes were launched by AMCs shortly after the underlying narrative had already been priced in by the market, which historically reduced subsequent returns. Investors should evaluate whether a theme is in early innings or mature innings before committing capital.

Satellite allocation: how much is reasonable?

The widely-cited core-and-satellite approach to portfolio construction frames sectoral and thematic funds as satellite positions:

• Core (70-90%): diversified equity funds — large cap, multi cap, flexi cap, ELSS, index funds. Provides broad market exposure and the bulk of long-term return.
• Satellite (10-30%): sectoral, thematic, international, factor-based, or other concentrated positions expressing specific views.

Within the satellite, allocating no more than 5-10% to any single sectoral or thematic fund is a commonly-cited educational guideline. Concentration beyond this risks the satellite tail wagging the portfolio dog — a single sector-cycle downturn could drive multi-year underperformance of the entire portfolio.

Tax treatment

Sectoral and thematic funds are taxed identically to other equity-oriented mutual funds because they invest at least 65% (typically 80%+) of assets in domestic equity:

• Long-term capital gains (units held more than 12 months): 12.5% on gains exceeding Rs 1.25 lakh per financial year (post-Budget 2024 framework).
• Short-term capital gains (units held 12 months or less): 20%.
• Switching between schemes within an AMC is treated as redemption + fresh purchase, which triggers capital gains tax. This is particularly costly for investors who rotate between sectoral funds.

Common mistakes

• Chasing recent winners: entering an IT fund after a multi-year IT up-cycle, or a banking fund after a multi-year banking up-cycle, has historically been associated with subsequent underperformance. Sectoral leadership rotates, and the strongest performers of the past five years are rarely the strongest of the next five.
• No exit plan: sectoral funds work best as tactical positions with a defined exit trigger — for example, valuation reaching a stretched threshold, or sector earnings growth slowing materially. Investors who buy with no exit plan often hold through complete cycles, capturing the full drawdown.
• Confusing diversified outperformance with sector outperformance: when a flexi cap fund is doing well because it is overweight a particular sector, the investor may already have implicit exposure to that sector. Adding a sectoral fund on top creates double exposure.
• Ignoring expense ratios: sectoral funds often carry higher expense ratios than diversified funds. Over 5-10 year holding periods, this drag is meaningful.
• Excessive satellite allocation: committing 30-40% of the equity portfolio to a single thematic fund transforms the satellite into a quasi-core position with concentration risk that the original portfolio design did not anticipate.

The bottom line

Sectoral and thematic funds are concentrated-exposure tools, not replacements for diversified equity funds. They have the capacity to outperform substantially during a sector or theme up-cycle and to underperform substantially during a down-cycle. Used as a small satellite allocation (5-15% of the portfolio) with a defined investment thesis and exit plan, they can express a long-term economic view in a diversified, tax-efficient vehicle. Used as a core allocation or chased after a multi-year rally, they have historically been associated with disappointing outcomes for retail investors. The decision to use these funds is less about timing skill and more about disciplined concentration sizing within a broader portfolio framework.

Frequently asked questions

What is the difference between a sectoral and a thematic fund?

A sectoral fund invests in a single specific sector (banking, IT, pharma). A thematic fund invests across multiple sectors that share a common theme (manufacturing, consumption, ESG). Thematic funds are typically less concentrated than sectoral funds because the theme can span 3-7 sectors, but they still carry meaningfully more concentration risk than diversified funds.

How are sectoral and thematic funds taxed?

Both are categorised as equity-oriented funds. LTCG (units held more than 12 months) is taxed at 12.5% on gains above Rs 1.25 lakh per financial year. STCG (12 months or less) is taxed at 20%. These rates apply per the post-Budget 2024 framework.

What percentage of a portfolio is reasonable for sectoral exposure?

Most educators frame sectoral and thematic funds as satellite allocations of 5-15% of the equity portfolio. Going materially beyond 15% in a single sector creates concentration risk that can cause sustained portfolio underperformance during sector down-cycles.

Can sectoral cycles be predicted reliably?

Historically, identifying sector cycle turning points in advance has been extremely difficult. The educational consensus is that sectoral funds are more about disciplined concentration choice than timing skill. Investors who rotated between sectors based on predictions often underperformed those who held diversified funds, after accounting for capital gains taxes on each rotation.
