Sectoral funds get a lot of attention because they post the highest returns when their sector is in favour. They also post the worst returns when the cycle turns. The same Indian pharma sectoral fund that returned 65% in 2020 was down 30% across 2021-22. The same IT sectoral funds that delivered 80%+ in 2020-21 fell 30%+ in 2022.
Most retail money flows into sectoral funds after a sector has already rallied 50-100% — classic performance chasing. Then it exits at the cyclical lows of the next correction. The result: investors capture the downside but miss the upside.
This guide explains how sectoral and thematic funds work, the Indian sectoral cycles you should know, the small tactical role they can play in a portfolio, and the discipline required to actually make money from them.
What Are Sectoral and Thematic Funds?
Sectoral Funds
Invest at least 80% in stocks from a single sector — Banking, IT, Pharma, FMCG, Infrastructure, Energy, Auto, Real Estate. Examples: ICICI Pru Banking & Financial Services Fund, Tata Digital India Fund, DSP Healthcare Fund, Nippon India Pharma Fund.
Thematic Funds
Invest in stocks linked to a broader theme that may span multiple sectors — Manufacturing, Digital/Tech, ESG, Infrastructure, Consumption. Themes are slightly more diversified than single sectors but still concentrated relative to diversified equity funds. Examples: Aditya Birla SL Infrastructure Fund, ICICI Pru ESG Exclusionary Strategy Fund, SBI Magnum Global Fund.
SEBI classifies both under one category — "Sector/Thematic" — with the 80% minimum allocation rule.
Indian Sectoral Cycles — A History Lesson
Indian sectors rotate aggressively. Understanding past cycles helps avoid buying at the top.

Every sector goes through 3-5 year cycles driven by macro themes, regulatory changes, global demand, and capital flows. Catching the right end of the cycle is what makes or breaks sectoral fund returns.
The Performance-Chasing Trap
SEBI's investor protection studies have repeatedly shown that retail flows into sectoral funds spike right before the sector tops, and outflows accelerate at the bottoms. The 2020-21 IT and Pharma boom drew record retail inflows in early 2021. Most of those investors held through the 2022-23 correction and exited at losses.
The Mathematical Reality:
If you enter a sectoral fund after it has rallied 80% in 18 months, you are buying at expensive valuations with the cycle late-stage. The probability of further gains is low, the probability of significant drawdown is high. The right entry is when the sector is out of favour, valuations are reasonable, and there is a visible positive catalyst — exactly when buying feels emotionally hardest.
When Sectoral/Thematic Funds Make Sense
Only in specific scenarios, and only as a small portion of equity allocation (5-10% max):
Cyclical bottom with clear catalyst: Pharma in 2020 (COVID treatment demand), Banking in 2003 (post-NPA cleanup), Capital Goods in 2022 (capex cycle revival)
Structural theme with multi-year runway: Digital adoption, manufacturing PLI scheme, energy transition
You have informed conviction: Not because someone told you, but because you understand the sector's drivers
When NOT to Use Sectoral Funds
As your first or only equity exposure
After a sector has already rallied 50%+ in the last 12 months
As a long-term buy-and-hold (sectoral funds are tactical, not strategic)
If you can't articulate why the sector is mispriced — that means you're trend-chasing
Sector Index Funds — A Cheaper Alternative
If you want sectoral exposure, low-cost index funds and ETFs often beat active sectoral funds:
Nifty Bank ETF (Nippon, ICICI Pru) — replicates the 12-stock Nifty Bank index
Nifty IT ETF (Nippon, ICICI Pru) — Indian IT majors
Nifty Pharma ETF (Nippon) — Indian pharma stocks
Nifty FMCG ETF (Nippon) — FMCG basket
Nifty PSU Bank ETF — PSU bank-only exposure
Sector ETFs charge 0.20-0.40% TER vs 1.5-2% for active sectoral funds. For pure sector exposure with no manager dependency, ETFs are often the better choice.
The Discipline Framework
If you must invest in sectoral or thematic funds, follow this discipline:
Cap allocation at 5-10% of equity portfolio. Never more.
A sectoral mutual fund invests at least 80% of its portfolio in stocks from a single sector — banking, IT, pharma, FMCG, infrastructure, energy, auto. The fund's performance is tied almost entirely to that one sector's cycle. When the sector booms (banking 2003-08, IT 2020-21), sectoral funds outperform. When the sector falls (pharma 2017-19, IT 2022), they underperform diversified equity funds severely.
Sectoral funds invest in one specific sector (Banking Fund, Pharma Fund, IT Fund). Thematic funds invest around a broader theme that may span multiple sectors (Manufacturing Theme, Digital/Tech Theme, ESG Theme, Infrastructure Theme, Consumption Theme). Themes are slightly more diversified than sectors but both are high-concentration bets compared to diversified equity funds. SEBI classifies both under 'Sector / Thematic' category requiring minimum 80% in the chosen sector/theme stocks.
Yes — they are among the highest-risk equity mutual fund categories due to concentration. Indian pharma sectoral funds returned 50-70% in 2020 (COVID theme), then lost 25-40% in 2021-22 as the theme faded. IT sectoral funds rallied 80%+ in 2020-21, then corrected 30%+ in 2022-23. PSU bank sectoral funds had 30-40% drawdowns multiple times in the 2010s on NPA worries. Single-sector concentration amplifies cycles in both directions.
Only as a small tactical allocation (5-10% of equity), and only if you have a strong conviction about the sector's near-term fundamentals. Never as your core equity holding. Most retail investors enter sectoral funds after a sector has already rallied 50-100% (chasing past performance) and exit at the lows of the next correction. The right entry is when the sector is out of favour with clear positive catalysts — exactly when it feels least exciting to buy.
Common categories include: Banking sectoral (Nifty Bank Index Fund, ICICI Pru Banking & Financial Services), IT sectoral (Tata Digital India, ICICI Pru Technology), Pharma sectoral (DSP Healthcare, SBI Healthcare, Nippon Pharma), FMCG sectoral (ICICI Pru FMCG, SBI Consumption Opportunities), Infrastructure thematic (Aditya Birla SL Infrastructure, ICICI Pru Infrastructure), and Energy (DSP Natural Resources). Index-based sector ETFs (Nifty Bank ETF, Nifty IT ETF, Nifty Pharma ETF) offer lower-cost alternatives to active sectoral funds.
Sectoral funds are typically tactical positions held 1-3 years based on sector cycle, not buy-and-hold positions like diversified equity funds. The discipline: enter when sector is undervalued with positive catalysts, exit when sector has rallied to historical highs with stretched valuations. The challenge: timing is hard. Most investors fail at this and would be better served using a diversified equity fund or flexi cap fund instead. If you can't time the sector cycle, don't play it.
