Sectoral and thematic mutual funds have been among the best and worst performers in any given year. An IT sector fund that delivered 65 percent returns in 2021 gave negative 20 percent in 2022. A pharma fund that topped charts during COVID underperformed for the next two years. This extreme performance cyclicality makes sectoral funds both exciting and dangerous. Before you allocate your SIP to a sector fund, you need to understand what you are getting into.
Sectoral vs Thematic: What Is the Difference?
A sectoral fund invests exclusively in one sector — IT, pharma, banking, or infrastructure. A thematic fund invests across a broader theme that may span multiple sectors — for example, a consumption theme might include FMCG, auto, retail, and hospitality stocks. Thematic funds are slightly more diversified than pure sectoral funds but still carry significant concentration risk compared to diversified equity funds.
| Fund Type | 1-Year Top Performer Return | 1-Year Bottom Performer Return | Volatility |
|---|---|---|---|
| IT Sector Fund | +65% (2021) | -22% (2022) | Very High |
| Pharma Sector Fund | +55% (2020) | -8% (2023) | High |
| Banking Sector Fund | +30% (2023) | -25% (2020) | High |
| Infra/Realty Theme | +52% (2024) | -15% (2019) | Very High |
| Diversified Flexi-Cap | +25% (average best) | -5% (average worst) | Moderate |
The return difference between the best and worst sectoral fund in any year can be as high as 80-90 percentage points. With a diversified fund, this gap is typically just 10-15 points. Concentration magnifies both gains and losses.
The Timing Challenge
The biggest problem with sectoral funds is that you need to get both the entry and exit timing right. Sectors go through multi-year cycles. The IT sector can outperform for 3-4 years and then underperform for the next 3-4 years. Most retail investors enter a sector after it has already rallied significantly (chasing past returns) and exit after it has already fallen (reacting to losses). This buy-high, sell-low pattern destroys returns.
Sector Performance Is Highly Cyclical
- Banking funds dominated 2016-2018, then underperformed in 2019-2020
- Pharma funds were the worst performers in 2018-2019, then became the best in 2020
- IT funds delivered exceptional returns in 2020-2021, then fell sharply in 2022
- Infrastructure and defence themes rallied 2023-2024 after years of underperformance
- No sector stays on top forever — rotation is the rule, not the exception
Who Should Invest in Sectoral Funds?
Sectoral funds are suitable only for investors who have deep understanding of sector-specific dynamics, can identify turning points in sector cycles, have a high risk tolerance, and are willing to actively monitor their investment. They are not suitable for passive SIP investors who want to set-and-forget. If you work in an industry and have genuine insight into its growth trajectory, a small sectoral allocation can make sense as a satellite holding.
The Right Way to Use Sectoral Funds
- Never allocate more than 10-15 percent of your total portfolio to sectoral or thematic funds
- Your core portfolio (85-90 percent) should always be in diversified funds
- Use sectoral funds as tactical additions, not core holdings
- Set a target return and exit when achieved — do not hold indefinitely
- Prefer thematic funds over pure sectoral funds for slightly better diversification
- Consider that your diversified flexi-cap fund already has meaningful exposure to the best-performing sectors
A good flexi-cap or multi-cap fund manager already allocates to the best-performing sectors through stock selection. By adding a sectoral fund on top, you may be doubling your exposure to that sector without realizing it. Always check the overlap between your existing funds and any new sectoral fund.
The graveyard of sectoral fund investors is filled with people who entered at the peak and exited at the bottom. Unless you have a genuine edge in understanding a sector, stick to diversified funds and let the fund manager handle sector allocation.
