HDFC Nifty 100 Equal Weight Index Fund: August 2026 Facts, Tracking, Risk and Tax

Summary: HDFC Nifty 100 Equal Weight Index Fund is an open-ended equity index scheme seeking to replicate the Nifty 100 Equal Weight Total Returns Index (TRI), subject to tracking error. Unlike a conventional market-cap-weighted Nifty 100 portfolio, its benchmark periodically resets constituent weights towards equality, changing the sources of concentration, turnover and rebalancing risk rather than removing equity-market risk. HDFC Mutual Fund’s September 2026 Fund Facts, reporting August 2026 information, states assets under management of ₹534.40 crore, an inception date of 23 February 2022, Regular and Direct plans with Growth option, a ₹100 minimum purchase/additional purchase amount, nil entry/exit load and annualised tracking error of 0.08% for both plans. The scheme’s September Fund Facts and the AMC’s September Index Insider publication display different expense-ratio figures for the same August reporting period: 0.88%/0.42% (Regular/Direct) in Fund Facts versus 1.00%/0.55% in Index Insider. The discrepancy is disclosed rather than silently resolved; investors should use the AMC’s current statutory TER report for the relevant transaction date. The fund’s riskometer is Very High, and passive replication does not guarantee benchmark returns. Under the Income-tax Act, 2025, applicable from 1 April 2026, qualifying short-term gains on equity-oriented fund units are generally taxed at 20% under section 196, while qualifying long-term gains above the aggregate ₹1.25 lakh threshold are generally taxed at 12.5% under section 198, subject to securities-transaction-tax and other statutory conditions. This article separates historical AMC disclosures from legal tax rules and contains no recommendation or return prediction.

Scheme Identity and What “Equal Weight” Means

HDFC Nifty 100 Equal Weight Index Fund is a named, open-ended passive mutual-fund scheme. Its investment objective, as stated by HDFC Mutual Fund, is to generate returns commensurate before fees and expenses with the performance of the Nifty 100 Equal Weight Index TRI, subject to tracking error. The objective is not a contractual promise to match the index or protect capital. The scheme is different from HDFC Nifty 100 Index Fund, which follows a market-cap-weighted benchmark, and different from HDFC Nifty 50 Index Fund, which follows a narrower large-company universe.

How equal weighting changes the portfolio

The Nifty 100 Equal Weight benchmark assigns broadly equal index weights to its 100 constituents at periodic rebalance dates. The AMC states that the benchmark is rebalanced quarterly to restore equal weights. In a market-cap-weighted index, the largest companies generally command greater weights. Equal weighting reduces single-stock weight concentration at a rebalance but can raise exposure to the smaller constituents within the Nifty 100 universe and can create more turnover when prices diverge between rebalances.

The equal-weight label should not be interpreted as equal exposure at every moment. Daily market movements change actual weights, cash and corporate actions cause temporary deviations, and a passive fund may use permitted instruments to manage flows. The investor bears full equity-market risk, possible sector tilts and the operational costs of periodic index changes. The index composition itself changes under its methodology; the AMC must respond to additions, deletions and corporate actions.

Verified Scheme Facts from September 2026 AMC Documents

The latest specific Fund Facts located for this analysis is HDFC Mutual Fund’s September 2026 factsheet, with portfolio and scheme figures as of 31 August 2026. The facts are historical snapshots, not live 15 October 2026 values. Scheme assets, NAV, expense ratios and holdings can change after the reported date. The current Scheme Information Document (SID), Key Information Memorandum (KIM), addenda and statutory TER disclosure should control an actual transaction.

Fund management and portfolio disclosure

The September Fund Facts names Nandita Menezes and Arun Agarwal as fund managers, with the stated management-effective dates of 29 March 2025 and 4 March 2022 respectively. The document reports 50.79% equity turnover and total turnover for its stated period. Its August-end top holdings include Divi’s Laboratories, Eternal, Lodha Developers, TVS Motor, Bajaj Auto, Bosch, LTM, HCL Technologies, Samvardhana Motherson and Titan, each shown near the 1% range. These are historical constituents, not suggestions to buy or sell those shares; actual weights change continuously.

Expense-Ratio Disclosure: Two AMC Publications Differ

A substantive verification issue appears in HDFC Mutual Fund’s own September 2026 material. The two-page September Fund Facts for this exact scheme reports total expense ratio as on August 2026 of 0.88% per annum for the Regular Plan and 0.42% for the Direct Plan. The AMC’s September Index Insider, in its Index Fund & FOF Reckoner labelled as of 31 August 2026, reports 1.00% for Regular and 0.55% for Direct. The publications therefore cannot be treated as one internally consistent snapshot for this metric.

This article does not select a “correct” figure without a reconciled official explanation. The difference may reflect a timing, reporting-basis or document-version issue, but none of those explanations should be asserted as fact without AMC confirmation. For any cost calculation, identify the precise TER effective on the relevant date and plan. An annual TER is an ongoing fund expense reflected in NAV, not a separate invoice normally paid by the investor. Differences in TER can create a tracking gap even where both plans hold the same underlying portfolio.

Tracking Error, Tracking Difference and Rebalancing

Tracking error is not the same as underperformance

Tracking error measures the variability of the difference between the scheme and benchmark returns over an observation period. Tracking difference describes the level of return difference between the scheme and the benchmark over a stated period. A small tracking error does not guarantee the fund earns the benchmark return; a relatively stable drag from expenses can coexist with low variability. Both measures depend on the exact plan, data window, frequency and benchmark total-return convention.

The September Fund Facts reports annualised tracking error of 0.08% for Regular and 0.08% for Direct based on daily rolling returns over the previous twelve months. This is a backward-looking calculation, not a maximum tracking error for the future. Cash holdings, corporate actions, market liquidity, securities lending, rebalancing execution, taxes and transaction costs can influence tracking. The fund’s strategy is passive but still requires operational execution and controls.

Equal-weight rebalance can increase turnover

Quarterly equal-weight resets can require selling constituents whose market values have risen relative to peers and buying those whose relative weights have fallen. The mechanism changes portfolio weights and transaction costs. It is not a prediction that equal weighting will outperform market-cap weighting. The two benchmarks can diverge materially when a small number of the largest stocks drive the market or when the broader large-cap group moves differently. A benchmark methodology document and the AMC portfolio statement are needed for a date-specific sector or constituent analysis.

Riskometer and Investor-Level Risks

The scheme’s August 2026 riskometer is Very High. The label is a regulatory risk disclosure, not a probability estimate or return forecast. An investor can suffer material capital loss despite the scheme being diversified across approximately 100 benchmark constituents. Market drawdowns, valuation compression, liquidity events, concentrated sectors, index methodology changes and operational tracking deviations all remain possible.

Income-tax Act, 2025: STCG, LTCG and the ₹1.25 Lakh Threshold

The Income-tax Act, 2025 applies from 1 April 2026. Units of an equity-oriented mutual fund generally receive the special equity capital-gains treatment if the fund meets the statutory equity-investment definition and the relevant securities transaction tax (STT) conditions are satisfied. Under section 196, qualifying short-term capital gains are generally taxed at 20% plus applicable surcharge and cess. Under section 198, qualifying long-term capital gains exceeding the aggregate ₹1.25 lakh threshold are generally taxed at 12.5% plus applicable surcharge and cess. The ₹1.25 lakh limit is an aggregate statutory threshold for eligible gains, not a separate allowance for each scheme or redemption.

Units of equity-oriented funds are generally long-term when held for more than twelve months; units held for twelve months or less are ordinarily short-term. Each SIP instalment is a separate acquisition lot, so a single redemption can contain both short-term and long-term lots. STT on redemption is relevant to the statutory concessional treatment. The precise holding period, transfer date, cost and grandfathering provisions where applicable should be checked before finalising a tax return.

Illustration of capital gains, not a return forecast

The illustration assumes an individual has no other eligible section 198 long-term gains during the tax year, relevant STT conditions are satisfied and no special basic-exemption adjustment, loss set-off, treaty or other exception applies. Actual tax may differ. Equity capital losses are subject to the normal capital-gains set-off and carry-forward conditions where applicable; the severe VDA loss restriction does not apply merely because an index fund holds equity securities.

Growth Option, Distributions and TDS

The September Fund Facts identifies Growth option under both Regular and Direct plans. Growth units do not ordinarily make periodic income-distribution payments merely because the underlying portfolio receives company dividends. Those dividends and other income affect the scheme’s NAV according to fund accounting. A redemption or switch can create a taxable capital-gains event even though the investor receives no separate distribution. If any future scheme addendum changes options or distributions, the operative terms must be checked.

The Income-tax Act, 2025 section 393(1) includes withholding rules for income in respect of mutual-fund units, subject to statutory thresholds and recipient status. That distribution-income withholding rule should not be casually applied as a 10% TDS on every Growth-option redemption: capital-gains withholding and non-resident payment rules must be considered separately. NRIs should also examine tax residency, applicable DTAA provisions, account route, repatriation conditions and the payer’s withholding obligations.

SEBI 2026 Regulations and Mandatory Investor Disclosures

The Securities and Exchange Board of India (Mutual Funds) Regulations, 2026 were notified on 14 January 2026 and came into force on 1 April 2026. The framework governs mutual-fund operations and disclosures alongside SEBI circulars and scheme documents. For a specific index scheme, the SID, KIM, portfolio disclosures, TER reports, riskometer, scheme factsheet and material addenda are the relevant primary records. A marketing presentation or older factsheet cannot supersede a newer legally operative addendum.

Passive investing does not remove the need to understand the scheme’s investment objective, replication limits, benchmark composition, permitted derivatives, expense rules, securities lending policy, liquidity and tax consequences. The scheme name does not make the investment low-risk or tax-exempt. Neither SEBI registration of the mutual fund nor benchmark licensing is an assurance of performance, principal protection or suitability for any particular investor.

Accounting and Recordkeeping for Investors

An individual holding mutual-fund units as investments should maintain the unit allotment statements, consolidated account statements, bank payments, SIP dates, cost of each lot, redemptions, STT evidence and capital-gain statements. For a company or other reporting entity, accounting depends on the applicable framework and business purpose. AS 13 may be relevant under Indian GAAP; entities applying Ind AS should evaluate Ind AS 109 classification, fair-value measurement and income-statement/OCI treatment as appropriate. The tax computation and accounting carrying value need not be identical.

A reconciliation should distinguish units purchased, bonus or corporate-action units if any, switches, redemptions and closing units. Expense ratios are reflected in scheme NAV and should not be duplicated as an investor-level deduction from capital gains. A switch between schemes can be a transfer for tax purposes even when the money remains within the same fund house. Any scheme-specific exemption from exit load is a separate commercial matter from income-tax treatment.

Reading the Historical Data Responsibly

The AMC’s September 2026 material gives a historical AUM of ₹534.40 crore and a Regular Plan Growth NAV of ₹17.4129 as at 31 August 2026. It reports 1-year Regular Plan Growth performance of 9.05% versus 10.18% for the benchmark over the specified historical period, but that backward-looking comparison is not evidence of future results. This article does not rank the scheme against peers or imply that either historical figure is an expected return. Any later publication should refresh AUM, NAV, TER, holdings and riskometer using dated AMC documents.

The key editorial distinction is between verifiable historical scheme characteristics, changing operating metrics and stable statutory principles. In particular, the two different August TER figures from HDFC publications must be treated as an unresolved disclosure discrepancy until the AMC’s live statutory TER record or a formal clarification reconciles them. Readers should not use either number as a guaranteed current cost on 15 October 2026.

Frequently Asked Questions

1. Is HDFC Nifty 100 Equal Weight Index Fund actively managed?

It is an index-tracking passive scheme, but the AMC must still manage cash flows, replication, corporate actions and rebalancing.

2. What is the scheme’s benchmark?

The Nifty 100 Equal Weight Total Returns Index (TRI), according to the September 2026 AMC Fund Facts.

3. What AUM and tracking error were disclosed for August 2026?

The AMC Fund Facts reports ₹534.40 crore AUM and 0.08% annualised tracking error for each plan, using the stated historical methodology.

4. Which TER should be used for the Regular and Direct plans?

Two September 2026 AMC publications show different August figures. The operative current statutory TER report and any AMC clarification should be checked rather than assuming one is definitive.

5. Is the scheme low risk because 100 stocks are equally weighted?

No. The August 2026 riskometer is Very High; diversification does not prevent material equity-market loss.

6. Is there an exit load?

The September 2026 Fund Facts says nil entry/exit load, subject to any subsequently operative scheme addenda.

7. How are redemptions taxed in tax year 2026–27?

Qualifying STCG is generally 20% under section 196 and qualifying LTCG above the aggregate ₹1.25 lakh threshold is generally 12.5% under section 198, plus applicable levies and subject to conditions.

8. Does a monthly SIP have one common holding period?

No. Each instalment normally has its own acquisition date and cost; redeemed units must be classified lot by lot.

Key Takeaways

• The scheme tracks Nifty 100 Equal Weight TRI and resets constituent weights periodically; it is not the cap-weighted Nifty 100 fund.
• September 2026 Fund Facts reports August AUM ₹534.40 crore, minimum purchase ₹100, nil exit load and 0.08% historical tracking error.
• Two official AMC September publications disclose different August TER figures; the live statutory TER report is needed to resolve the discrepancy.
• The riskometer is Very High and index replication does not ensure capital protection or benchmark-equivalent returns.
• For tax year 2026–27, sections 196 and 198 of the Income-tax Act, 2025 govern qualifying equity-oriented fund STCG/LTCG.
• The ₹1.25 lakh long-term threshold is aggregate, not per scheme; each SIP lot has a separate holding period.
• Historical AMC facts, changing costs and statutory tax rules must be kept distinct in editorial and tax records.
