Start by defining the sector thesis and the fund’s role beside your existing investments. Then verify the portfolio’s real concentration, compare the current total expense ratio (TER) on a like-for-like plan basis, test the record through different market phases, and decide whether you can tolerate the fund’s drawdowns and holding period. There is no universal “acceptable” fee, return or number of holdings: the right decision depends on the scheme’s current disclosures, your overlap with other funds and your ability to live with sector-specific losses.
What a sectoral mutual fund is—and why concentration changes the decision
In India, SEBI describes thematic and sectoral mutual funds as schemes focused on a specific industry, sector or theme. AMFI gives infrastructure, banking, technology and pharmaceuticals as examples. Unlike a diversified equity fund, a sectoral fund deliberately narrows its opportunity set. Companies may be different sizes and business models, yet still respond to the same interest-rate cycle, regulation, commodity cost, technology shift or economic slowdown.

AMFI’s investor material puts the central risk plainly: “Since these funds focus on just one sector of the economy, they limit diversification, and are thus riskier.” Treat that as a portfolio-construction warning, not a prediction that every sector fund will lose money. A fund can own 40 stocks and remain highly concentrated if its top positions dominate assets or all holdings share one economic driver.
For that reason, evaluate concentration before looking at past returns. Record the sector definition used in the scheme documents, the number of holdings, the weight of the top 10 positions, the largest single-stock weight, cash or equivalents, market-cap mix, any foreign exposure, turnover indicators and overlap with funds you already own.

Decide the fund’s job before comparing schemes
Use a sectoral fund as a satellite, not an automatic core
A broad diversified fund can provide the core exposure for investors who need one portfolio holding to spread risk across industries. A sectoral fund is better viewed as a satellite position: a limited allocation expressing a reasoned view about one part of the economy. The allocation should be small enough that a severe sector drawdown does not derail essential goals, while large enough to matter if the thesis works.
Write the thesis in one paragraph
State what you believe will improve in the sector, which evidence would support that belief, and what would invalidate it. A thesis based only on a recent price rise is not a process. Include the expected drivers—such as credit growth, public investment, drug demand or technology adoption—along with the risks that could reverse them.
Set limits before buying
- The fund’s role in your total portfolio and the maximum percentage you will allocate.
- The largest drawdown you could withstand without selling in panic.
- A minimum holding horizon long enough for the sector cycle you are underwriting.
- A rebalancing rule, including when you will trim an oversized position.
- Specific evidence that would disprove the sector thesis.
If you cannot write these conditions, a broad diversified fund may be easier to use as a core allocation. Sector exposure can also arise accidentally when several diversified funds own the same industry, so inspect the whole portfolio rather than treating each scheme in isolation.
Inspect the mandate and the actual holdings
Read the scheme documents, not just the name
Use the latest portfolio disclosure and the scheme information document. Confirm how the scheme defines its sector or theme, the permitted securities, single-stock or group limits, derivatives policy, cash range and any ability to invest outside the headline industry. Two funds with different labels may own many of the same companies; two funds with similar labels may have very different market-cap and sub-industry exposure.
Measure concentration in several ways
- Top-10 weight: add the percentages of the ten largest positions. A high total means the outcome depends heavily on a few names.
- Largest position: note the single-stock weight and whether it approaches the scheme’s stated limit.
- Number of holdings: useful context, but not proof of diversification.
- Market-cap mix: separate large-, mid- and small-cap exposure because liquidity and drawdown behaviour can differ sharply.
- Cash and equivalents: identify whether cash is structural, temporary or a result of subscriptions and redemptions.
- Foreign exposure: record overseas securities or receipts if the mandate permits them.
- Turnover indicators: frequent changes can increase transaction costs and make the stated strategy harder to evaluate.
Check economic overlap with your other funds
Create a combined list of your existing funds’ major holdings and compare it with the candidate’s latest list. Look through subsidiaries, financial groups and common suppliers where relevant. The important question is not whether company names repeat once, but whether the same sector drivers dominate several holdings. A banking fund added to diversified funds already heavy in lenders may increase one risk far more than its purchase amount suggests.

Recheck after each new disclosure
Portfolios change. Save the date of every disclosure you use, then repeat the concentration and overlap check after the next one. A fund that was diversified across sub-industries can become a narrow bet after the manager sells several positions, and a temporary cash balance can disappear without notice.
Compare expense ratios without inventing a cutoff
Understand what TER measures
AMFI defines the total expense ratio as the operating costs charged as a percentage of a scheme’s daily net assets. TER must be disclosed daily on the fund and AMFI websites. SEBI’s TER and performance circulars provide the regulatory reference for these disclosures. Use the current figure and its effective date; an old factsheet or a marketing page may not reflect today’s charge.

Compare direct and regular plans separately
SEBI says the underlying portfolio is the same in direct and regular plans. A regular plan bought through an intermediary has a higher expense ratio because it includes intermediary commission. Compare a candidate’s direct plan with other direct plans, and regular with regular. Do not call one “cheaper” by comparing unlike plan types.
A direct plan may suit an investor who can select, transact and monitor without an intermediary. A regular plan may provide distribution or advisory support that the investor values. The decision is not simply a race to the lowest number: assess the service you receive, the complexity of the portfolio and whether you will actually follow the process.
Include every disclosed cost
Record exit load, transaction costs and taxes as shown in the scheme documents. A low TER does not erase a cost triggered by an early redemption, nor does it make a concentrated portfolio safe. Investor.gov explains the compounding effect of fees: “Even small differences in fees can mean large differences in returns over time.” That is why cost deserves a line in your comparison, but not the only line.
Judge cost against what you receive
There is no authoritative fee threshold that can be generalized across all sectoral funds, dates and plan types. Compare current TERs among genuinely comparable schemes, then ask whether the difference is justified by the portfolio’s concentration, implementation, liquidity, disclosure quality and the manager’s repeatable process. A lower fee attached to an unsuitable mandate is still the wrong purchase.

Use track record as evidence, not a promise
Start with the correct comparison set
Compare the same plan and share class, the fund’s stated benchmark and a relevant category reference. Keep the return basis consistent—growth with growth, and the same treatment of distributions. Mixing direct and regular plans or comparing a sector fund with a broad-market index can create a misleading ranking.
Prefer rolling periods to a single headline return
Examine rolling one-, three- and five-year periods where the fund has enough history, and include periods of rising markets, falling markets and sector-specific stress. Record benchmark-relative results and the size and duration of drawdowns. A fund that wins one calendar year but suffers unusually deep losses in downturns may not fit an investor’s loss capacity.
Read the story behind the numbers
Investor.gov states: “A fund’s past performance is not as important as you might think because past performance does not predict future returns.” Historical results can still show how volatile or stable the fund has been. Read the manager’s tenure, investment process, mandate changes, portfolio turnover and reasons for major deviations from the benchmark. Look for persistence across different market phases rather than a one-year rank.
Check the wider organization
SEBI investor guidance recommends reviewing the performance of other schemes launched by the mutual fund and sponsor, as well as the record of key personnel. That review is not a guarantee. It helps you distinguish a repeatable process from a result produced by one short-lived cycle or one manager who has since left.

Assess risks specific to the sector
Sector funds can be hurt by events that diversified funds may absorb more easily. Depending on the industry, ask how the portfolio would respond to:
- New regulation, taxation or licensing rules.
- Interest-rate changes that alter borrowing costs or demand.
- Commodity-price shocks affecting margins.
- A recession or a change in the business cycle.
- Technology that makes products or processes obsolete.
- Supply-chain, currency or geopolitical disruption.
- Liquidity stress in smaller companies during a broad sell-off.
Mutual funds are not guaranteed or insured by the FDIC or another government agency, and investors can lose some or all of their money, according to Investor.gov. In India, use the scheme’s risk-o-meter and risk factors as disclosed, but do not treat a label as a substitute for reading the holdings and drawdown history.
A step-by-step selection process
- Define the allocation. Write the portfolio role, maximum weight, minimum horizon, acceptable drawdown and rebalancing rule.
- State the sector thesis. Identify the expected drivers and the evidence that would invalidate the view.
- Shortlist comparable schemes. Group direct plans with direct plans and regular plans with regular plans; confirm that each mandate actually targets the sector you intend to own.
- Download current documents. Use the latest scheme information document, portfolio disclosure, factsheet and risk disclosure. Note publication dates and the plan or option you are considering.
- Map concentration. Record holdings, top-10 and largest-position weights, market-cap mix, cash, foreign exposure and turnover indicators.
- Measure overlap. Compare the candidate’s positions and sector drivers with every fund already in your portfolio.
- Record costs. Capture current daily TER, plan type, exit load and other disclosed expenses. Keep one row for each plan rather than blending them.
- Test the record. Review rolling returns, benchmark-relative results, volatility and drawdowns across different market phases, using a consistent return basis.
- Review governance. Read the sponsor and manager record, process continuity, scheme-document quality and any disclosed litigation or penalties.
- Make a written decision. Buy only if the thesis, deliberate exposure, cost, risk and holding period all fit your plan. Otherwise, keep the diversified core or continue researching.

How to monitor a fund after purchase
Monitor the thesis, not the daily price
Set review dates around new portfolio disclosures and material sector developments. Check whether the holdings still express the original thesis, whether concentration has increased, and whether overlap with the rest of your portfolio has changed. A price decline alone does not invalidate a thesis; a regulatory change or deterioration in the underlying driver might.
Rebalance by rule
When a sector fund grows beyond the maximum weight you set, trim according to your written rule rather than a market forecast. Consider exit loads, taxes and transaction costs shown in the scheme documents before acting. Rebalancing is a risk-control decision, not a guarantee of a better return.
Investigate process changes
Review a manager departure, a mandate amendment, a sharp change in turnover or a sustained move away from the stated sector. These events may justify a fresh suitability assessment even when recent returns look strong.

Common mistakes and how to correct them
Choosing the recent winner
Problem: buying after a one-year ranking or a news-driven rally. Correction: use rolling periods, drawdowns, benchmark-relative results and the sector thesis.
Assuming more holdings means diversification
Problem: treating a long holdings list as protection from a common industry shock. Correction: calculate top-10 and largest-position weights and identify shared economic drivers.
Comparing the wrong plans
Problem: comparing a direct-plan TER with a regular-plan TER or mixing plan share classes in performance tables. Correction: compare like for like and include intermediary service in the decision.
Ignoring portfolio overlap
Problem: believing a new fund adds diversification because its name is different. Correction: perform a look-through holdings and sector-driver comparison across all funds.
Using an old fee or holdings snapshot
Problem: relying on a dated factsheet. Correction: record the date and use the latest disclosure; TER is disclosed daily and portfolios change.
Skipping governance checks
Problem: focusing only on returns while ignoring sponsor history, manager continuity, litigation or penalties. Correction: complete the governance row in your comparison table before investing.
When the answer should be “not this fund”
Do not buy when you cannot explain the sector thesis, when the holdings duplicate risks you already have, when the plan and TER are unclear, or when a plausible drawdown would force a sale. Also pause if the fund’s history is too short for the market phases you need to evaluate and the available documents do not fill that gap. A broad diversified fund may be a more suitable core choice while you retain a smaller, explicitly managed sector view—or no sector allocation at all.

Recommend a sectoral mutual fund to yourself only when four tests pass: you can explain why the sector belongs in the portfolio; current holdings add deliberate rather than accidental exposure; the TER and plan type are justified after all disclosed costs; and your drawdown limit and holding horizon match the fund’s risk. Use current SEBI, AMFI and scheme disclosures for every number, label the date and geography of each comparison, and treat the track record as evidence about behaviour—not a promise of future returns.
