Alongside the smallcap-vs-midcap-vs-multicap conversation, a different kind of PMS categorisation has become increasingly common in Indian HNI portfolios: sector and thematic strategies — portfolios built around a specific industry or structural economic trend, rather than a market-cap band.
Banking-focused PMS, technology-focused PMS, and manufacturing and infrastructure-themed strategies have all moved from niche allocations into mainstream HNI conversations in recent years.
This guide explains how sector and thematic PMS strategies work, what’s driving the major themes in India right now, and — just as importantly — the concentration risks that make this category meaningfully different from a diversified PMS strategy.
What Is a Sector and Thematic PMS, and How Is It Different from Diversified Strategies?
A sector PMS concentrates its portfolio within a single industry — banking and financial services, for instance — while a thematic PMS invests across a broader structural trend that may span multiple sectors (such as “manufacturing growth” or “digital transformation,” which can touch IT, capital goods, electronics, and more).
Both differ fundamentally from smallcap, midcap, multicap, or flexicap PMS strategies, which categorise by company size and typically diversify across industries.
Sector and thematic PMS, by contrast, deliberately concentrate exposure — betting that a specific industry or trend will outperform the broader market over the chosen time horizon.
Why Sector & Thematic PMS Has Gained Real Momentum in India
India’s PMS industry has grown substantially in recent years, and sector-focused strategies have been a meaningful part of that growth — driven by genuine structural stories playing out in the Indian economy: a sustained domestic manufacturing push, a large-scale infrastructure investment cycle, ongoing digital transformation across industries, and financial inclusion expanding the banking and fintech opportunity.
Investors drawn to a specific structural narrative — rather than a general “buy the market” approach — increasingly look to sector-focused PMS to express that conviction.
That said, sector leadership rotates meaningfully from year to year — manufacturing and capital expenditure themes, for example, have led PMS conversations in some recent years, while technology-focused strategies have gone through periods of weaker relative performance during others.
This rotation is exactly why understanding a strategy’s approach to sector timing matters as much as the theme itself, covered in more detail below.
Banking & Financial Services (BFSI) PMS Strategies
Banking and financial services PMS strategies invest across banks, NBFCs, insurance companies, and increasingly fintech-linked businesses.
This sector benefits from structural tailwinds like rising financial inclusion, digital payments adoption, and credit growth as the broader economy expands.
What to understand: BFSI is a relatively large, liquid sector with meaningful weight in broader indices already — so a dedicated BFSI PMS is making a concentrated bet on banking-specific cycles (credit growth, asset quality, interest rate movements) rather than a genuinely under-owned or niche opportunity.
Technology & IT PMS Strategies
Technology-focused PMS strategies invest across IT services, software, and increasingly AI-linked and digital infrastructure businesses.
India’s IT sector has been evolving from traditional services toward higher-value areas like cloud, cybersecurity, and AI-driven offerings, with the broader industry targeting substantial global scale by the end of the decade.
What to understand: IT-focused strategies have historically shown meaningful sensitivity to global demand cycles (particularly US/European client spending), currency movements, and periods of slower earnings momentum—a genuinely different risk driver than the domestically focused themes below.
Manufacturing & “Make in India” PMS Strategies
Manufacturing-themed PMS strategies invest across capital goods, industrials, electronics manufacturing, auto components, and related sectors benefiting from India’s push toward domestic manufacturing capacity.
Government programmes like the Production-Linked Incentive (PLI) scheme — which has attracted well over ₹2 lakh crore in actual investment across more than a dozen sectors — have been a meaningful structural driver behind this theme, alongside the broader “China Plus One” supply chain diversification trend.
What to understand: Manufacturing is a capital-intensive, cyclical sector tied closely to capital expenditure cycles, government policy continuity, and global trade dynamics — a strategy here is making a multi-year bet that India’s industrial capacity build-out will continue.
Infrastructure PMS Strategies
Infrastructure PMS strategies invest across construction, engineering, cement, logistics, transportation, and energy-linked infrastructure businesses — sectors directly tied to India’s public and private infrastructure investment cycle.
What to understand: Infrastructure investing is heavily influenced by government capital expenditure priorities and project execution timelines, meaning policy continuity and budget allocation trends matter enormously to this theme’s outlook — a sector where political and policy risk deserves as much attention as company-level fundamentals.
Other Emerging Sector Themes Worth Knowing
Beyond the four core themes above, several other sector-specific PMS conversations have gained traction recently:
- Defence & Aerospace: Benefiting from domestic manufacturing push in strategic sectors and rising defence exports
- Green Energy & Renewable Infrastructure: Tied to India’s energy transition, including solar, wind, and battery storage
- Healthcare & Pharmaceuticals: Focused on pharma manufacturing, hospitals, diagnostics, and healthcare services
- Speciality Chemicals: A structural China Plus One beneficiary theme, alongside manufacturing more broadly
- Semiconductors: A newer, longer-horizon theme tied to India’s push to build domestic chip design, fabrication, and packaging capacity
The Unique Risks of Sector & Thematic Concentration
Sector and thematic PMS strategies carry risks that go meaningfully beyond what a diversified multicap or flexicap PMS investor typically faces:
- Cyclicality: Nearly every sector theme moves through cycles — a manufacturing or infrastructure theme that looks compelling today can face a multi-year lull if capital expenditure cycles slow
- Correlation risk: Because the entire portfolio sits within one sector or theme, a sector-specific shock (regulatory change, global demand shift, commodity price move) affects the entire portfolio simultaneously, unlike a diversified strategy where other holdings can offset a weak sector
- Sector rotation risk: Sector leadership changes over time, and a strategy’s ability to recognise and rotate ahead of a theme losing momentum matters as much as the initial theme selection — this rotation discipline, not just the theme itself, tends to separate strong sector PMS outcomes from weak ones
- Timing risk: Entering a sector-focused strategy near the peak of that sector’s cycle, based on strong recent returns, is a common and costly mistake — directly connected to Mistake #1 in our guide to common PMS/AIF investing mistakes
How Much of Your Portfolio Should Go Into Thematic PMS?
Given the concentration risks above, most experienced advisors treat sector and thematic PMS as a satellite allocation — a smaller, deliberately sized portion of an overall portfolio — rather than a core holding.
A diversified multicap or flexicap PMS (or a combination of strategies across categories) typically forms the core, with sector-specific conviction bets layered on top in a bounded, clearly sized allocation.
This mirrors the broader diversification principle covered in our guide on common HNI investing mistakes — avoiding over-concentration in any single strategy.
How to Evaluate a Sector/Thematic PMS Strategy
1. Understand the structural thesis — is the theme backed by a genuine multi-year economic driver (policy support, demand growth, capacity expansion), or a shorter-term narrative?
2. Check the manager’s sector rotation track record — has the strategy shown discipline in rotating away from a theme as its cycle matures, or has it remained overweight through clear signs of slowing momentum?
3. Review performance through a full sector cycle, not just the theme’s strongest recent period — see our guide on comparing PMS returns properly
4. Size the allocation deliberately — treat it as a satellite position, not a core holding, given the concentration risk involved
5. Confirm the fee structure — sector strategies with strong recent performance are sometimes priced at a premium; understand exactly what you’re paying via our guide to PMS fee structures

Frequently Asked Questions
Are sector/thematic PMS strategies riskier than diversified PMS strategies?
Generally yes, due to concentration risk — a sector-specific PMS lacks the natural diversification of a multicap or flexicap strategy, meaning both the upside and downside are typically more pronounced.
How do I know which sector theme is right for me?
Rather than chasing whichever theme has performed best recently, evaluate the structural driver behind the theme, your own conviction in that long-term narrative, and how the allocation fits within your broader, already-diversified portfolio.
Can I combine multiple sector-themed PMS strategies?
Yes, some HNIs combine a few sector-focused allocations (for example, manufacturing and BFSI together) alongside a diversified core holding—though this requires careful portfolio-level risk management to avoid unintentional over-concentration across correlated sectors.
How is a thematic PMS different from a sector mutual fund?
The underlying concept is similar, but PMS offers a more concentrated, discretionary, directly-held portfolio typically with fewer holdings than a sectoral mutual fund, along with the fee structure and minimum investment differences that apply to PMS more broadly.
What percentage of my portfolio should be in sector/thematic PMS?
There’s no universal number, but most advisors suggest treating thematic PMS as a smaller satellite allocation rather than a core holding, given the concentration risk—the specific percentage should reflect your conviction level and overall risk tolerance.
