Sectoral and Thematic Funds: A High-Risk, High-Reward Game?
Dive deep into sectoral and thematic funds to understand their high-risk, high-reward nature. Learn the difference, the risks involved, and who should consider these specialised investments for their portfolio.

In the world of mutual funds, the golden rule is often to “diversify, diversify, diversify.” But what if you want to make a concentrated bet on an industry you believe is poised for explosive growth? This is where sectoral and thematic funds enter the picture.
These funds are the spicy side dishes of the investment world—they can add a powerful kick to your portfolio, but they aren’t meant to be the main course. Let’s break down what they are, how they work, and whether they deserve a place in your investment strategy.
Key Takeaways
- Sectoral funds invest in companies from a single, specific sector, like IT, banking, or pharma.
- Thematic funds invest in companies across various sectors that are connected by a common idea, such as “Make in India” or “Electric Vehicles.”
- Both are high-risk, high-reward investments due to their concentrated nature and should ideally form a small part of a well-diversified portfolio.
Sectoral vs. Thematic Funds: What’s the Difference?
While they sound similar, sectoral and thematic funds differ significantly in their investment scope.
A sectoral fund puts all its eggs in one basket. For example, a banking sectoral fund will only invest in the stocks of banking companies. Similarly, a pharma fund will only hold shares of pharmaceutical and healthcare companies. According to SEBI regulations, these funds must invest at least 80% of their assets in their chosen sector.
A thematic fund, on the other hand, invests in a broader idea or a long-term trend that cuts across multiple sectors. For instance, an “Infrastructure” themed fund might invest in:
- Construction companies (Capital Goods sector)
- Cement and steel companies (Materials sector)
- Banks that finance these projects (Financials sector)
- Logistics companies (Services sector)
This structure makes thematic funds relatively more diversified than sectoral funds, but they are still far more concentrated than a typical diversified equity fund. They too must invest at least 80% of their assets in equities related to their specific theme.

Concentration: The Source of High Risk and High Reward
The biggest appeal of these funds is also their greatest weakness: concentration.
When a particular sector is booming, a sectoral fund can deliver spectacular returns. Think about IT funds during the tech boom or pharma funds during a health crisis. Because the fund is entirely focused on that one area, it reaps the full benefits of the upswing.
However, the reverse is also true. When that sector faces a downturn, the fund’s value can plummet dramatically. There’s no cushion from other sectors to soften the blow. This leads to higher volatility and cyclical performance. A sector that’s a market darling one year could be the worst performer the next, due to factors like regulatory changes, economic slowdowns, or shifts in consumer behaviour.
Key Risks of Sectoral and Thematic Investing
Before you get tempted by the high-return potential, it’s crucial to understand the risks:
- Lack of Diversification: This is the most obvious risk. If the sector or theme you’ve bet on goes through a prolonged rough patch, your investment will suffer significantly.
- Cyclicality: Many sectors, like infrastructure and banking, are cyclical. Timing your entry and exit is critical, and getting it wrong can lead to substantial losses.
- Regulatory Changes: An entire sector can be impacted by a single government policy. For example, changes in drug pricing policies can hurt pharma funds, while new NPA (Non-Performing Asset) rules can impact banking funds.
Performance: A Bumpy Ride vs. Steady Growth
To understand the risk-reward difference, let’s compare the historical performance of a sectoral index with a diversified one. Consider the Nifty IT index versus the broader Nifty 50 index.
Historically, the Nifty 50 has provided steady, long-term growth. In most long-term periods, it has delivered healthy annualized returns.
Now, look at the Nifty IT index. During the tech bull run fueled by global digitization (especially post-2020), IT funds delivered phenomenal returns, far outpacing the Nifty 50. However, they have also faced sharp corrections when the sector’s outlook turned negative due to global slowdowns or changing demand.
This illustrates the core concept: while a sectoral fund can deliver higher returns during a boom, it comes with a much bumpier ride and the risk of steep falls. A diversified fund, like a Nifty 50 index fund, provides more stable, though potentially less spectacular, growth.

Are These Funds Right for Your Portfolio?
Sectoral and thematic funds are not for everyone. They are best suited for:
- Experienced Investors: Those who have a deep understanding of the specific sector or theme they are investing in.
- High-Risk Appetite: Investors who are comfortable with high volatility and the possibility of significant losses.
- Tactical Allocators: Investors who want to make a strategic, short-to-medium-term bet on a particular trend.
These funds should not be the core of a beginner’s portfolio. Building a strong foundation with diversified equity funds is a much safer and more reliable approach to long-term wealth creation.
How to Invest in Sectoral and Thematic Funds Safely
If you are an experienced investor and decide to venture into this space, here are a few tips to manage the risk:
- Limit Your Allocation: Do not invest more than 5-10% of your total equity portfolio in sectoral or thematic funds. This helps contain the impact of any downturns.
- Have an Exit Strategy: These are not “buy and forget” investments. Have a clear plan for when you will exit, whether it’s based on a target return, a specific time horizon, or a change in the sector’s fundamentals.
- Don’t Chase Past Performance: A fund that was a top performer last year might not be this year. Invest based on your research and future outlook, not just historical returns.
In conclusion, sectoral and thematic funds are specialized tools, not foundational assets. They offer a chance to capitalize on specific market trends but demand a high level of diligence, risk tolerance, and a clear exit strategy. For most investors, they should remain a small, tactical part of a portfolio dominated by well-diversified funds.
