Thematic Funds vs Sectoral Funds: What is the Difference 2026
Priya was comparing an “IT Sectoral Fund” against a “Digital India Thematic Fund” and assumed they were basically the same thing with different names. They are not. Thematic funds vs sectoral funds is a distinction SEBI itself has recently sharpened, and understanding it changes how concentrated, and how genuinely diversified, your money actually is inside either one, especially now that both are officially separate categories.
Thematic Funds vs Sectoral Funds: The Core Difference
A sectoral fund invests at least 80% of its assets in a single industry, banking, pharmaceuticals, IT, or FMCG, and every major holding comes from that one sector. A thematic fund also invests at least 80% in line with its mandate, but the mandate is a broader idea that can pull in companies from several different sectors at once. A “Digital India” thematic fund might hold IT services companies, telecom providers, listed fintech firms, and logistics businesses that depend on digital infrastructure, all under one theme, even though those are clearly different industries.
SEBI Now Treats Them as Genuinely Separate Categories
For a long time, sectoral and thematic funds were grouped together under a single broad equity category, which blurred the practical distinction between them. As of February 2026, SEBI formally split them into two distinct categories, Sectoral Fund and Thematic Fund, each with its own classification. The 80% minimum investment mandate applies to both, but the split makes the underlying difference in portfolio construction, one industry versus one idea across several industries, an official regulatory distinction rather than just a naming convention fund houses used loosely.
Real Examples of Each
Common sectoral funds include banking and financial services funds, pharma and healthcare funds, IT funds, FMCG funds, auto funds, and energy funds, each confined to that one named industry. Common thematic funds include ESG funds investing in sustainability-aligned companies across sectors, consumption funds spanning FMCG, auto, and consumer durables, manufacturing funds covering capital goods and industrial companies, and infrastructure-as-theme funds that combine construction, cement, engineering, and logistics businesses rather than any single one of them alone. Infrastructure is a useful example of how blurry the line can get, since it is sometimes structured as a narrow sectoral bet and sometimes as a genuinely multi-sector theme, depending on how the specific fund is built.
Does the Extra Diversification in Thematic Actually Reduce Risk?
Somewhat, but less than the word “diversification” might suggest. Sector cycles can be extreme on their own, looking at 5-year rolling returns, banking has ranged from around 24% at its best to roughly -2% at its worst, pharma from about 32% down to -5%, and IT from around 35% down to -8%, spreads of 26 to 43 percentage points depending on the sector and the period measured. A thematic fund spreading its 80% across several sectors tied to one idea smooths out some of this, since not every sector within the theme moves in lockstep, but it does not remove the underlying concentration risk, since the fund is still betting heavily on that one theme playing out rather than the market broadly. Both remain considerably more concentrated than a genuinely diversified equity fund, a distinction I have covered in more depth in my guide on sectoral funds vs diversified funds.
Tax Treatment Is Identical
Both sectoral and thematic funds are equity-oriented, holding well above the 65% equity threshold, so both are taxed exactly the same way. Long-term gains after 12 months are exempt up to Rs. 1,25,000 a year, with the excess taxed at 12.5%, and short-term gains within 12 months are taxed at 20%. As with the broader sectoral versus diversified comparison, tax plays no role in choosing between a sectoral and a thematic fund, risk and conviction in the underlying idea do.
Thematic Funds vs Sectoral Funds at a Glance
| Factor | Sectoral Fund | Thematic Fund |
|---|---|---|
| SEBI category, from Feb 2026 | Sectoral Fund category | Thematic Fund category |
| Minimum mandate | 80% in one industry | 80% in stocks aligned to one theme |
| Number of industries covered | One | Typically several, bound by a common idea |
| Internal diversification | None | Some, across the theme’s underlying sectors |
| Examples | Banking, pharma, IT, FMCG, auto | ESG, consumption, manufacturing, Digital India |
| Tax treatment | Same as any equity fund | Same as any equity fund |
Checking Overlap If You Hold Both Types
A common mistake is assuming a sectoral fund and a related thematic fund automatically diversify each other, an IT sectoral fund alongside a Digital India thematic fund, for instance. In practice, the thematic fund likely holds a meaningful chunk of the same IT companies as its sectoral counterpart, simply diluted by the other sectors in the theme. Before treating the two as separate bets, it is worth checking the actual portfolio overlap between them using my mutual fund overlap guide, since holding both may add less genuine diversification than it appears to on paper.
Which Should You Choose
If you have genuine, specific conviction in one industry, a sectoral fund gives you the purest exposure to that call, with no dilution from unrelated sectors. If your conviction is broader, a belief in a trend like digitisation, sustainability, or rising consumption, rather than one specific industry, a thematic fund lets you express that view while spreading the bet across the several sectors that trend actually touches. Neither is a substitute for understanding what you are buying, since both require you to be right about a concentrated idea, not just picking a fund with a good recent return.
Conclusion
Thematic funds vs sectoral funds comes down to how narrow your bet actually is. A sectoral fund bets on one industry. A thematic fund bets on one idea that happens to run through several industries, which offers a little more internal diversification without escaping the core concentration risk either category carries. Now formally separated by SEBI as of February 2026, the two are no longer just different names for a similar product, they are distinct categories with genuinely different portfolio construction rules behind them.
Frequently Asked Questions
Can a fund switch between being classified as sectoral or thematic?
A fund’s category is generally tied to its stated mandate in the scheme document, so a shift would typically require a formal change in mandate and investor communication, rather than happening quietly through portfolio drift alone.
Is an infrastructure fund sectoral or thematic?
It depends on how the specific fund is built. Some infrastructure funds are structured narrowly enough to sit closer to a sectoral fund, while others explicitly span construction, cement, engineering, and logistics as a broader theme, which is a useful reminder to check a fund’s actual portfolio rather than assuming based on its category label alone.
Do thematic funds have lower expense ratios than sectoral funds since they are more diversified?
Not necessarily, expense ratios are set by the fund house and vary by scheme rather than by category, so it is worth comparing the actual expense ratio of the specific funds you are considering rather than assuming one category is systematically cheaper than the other.
Should a beginner start with a thematic fund since it sounds more diversified?
Not really. Even with its broader spread, a thematic fund still concentrates heavily around one idea, and a beginner is generally better served building a diversified core first, then adding either a sectoral or thematic satellite position only once they genuinely understand the specific bet they are making.
Does a thematic fund’s name always tell you which sectors it actually holds?
Not reliably. A theme like “consumption” or “manufacturing” is broad enough that different fund houses can interpret it differently, one manager’s consumption fund might lean heavily toward FMCG while another’s leans toward autos and durables. Checking the actual sector-wise portfolio breakdown in the factsheet is more reliable than assuming based on the theme’s name alone.
