India’s defense modernization story is real, and the numbers back it up. If you’re weighing an Indian Defence ETF against picking individual stocks, the starting point is understanding what these funds actually hold and what they cost you over time. The government’s defense capital expenditure has grown consistently over the past several years; the Atmanizbhar Bharat policy is pushing procurement toward domestic manufacturers, and companies like HAL, BEL, and Bharat Dynamics carry multi-year order books that represent genuine revenue visibility. This is a structural investment theme, not a short-term trade. The question serious investors face isn’t whether to be in Indian defense, it’s which vehicle actually gives you the best exposure to that growth.
Two exchange-traded funds now make that question worth examining closely: the Motilal Oswal Nifty India Defence ETF (NSE: MODEFENCE) and the Groww Nifty India Defence ETF. Both give retail investors a one-click entry into the defense theme, and both are relatively new products that track exactly the same underlying index. Whether “easy entry” translates to “smart entry” depends entirely on what you understand about what’s actually inside these funds, what they cost you in real terms, and what you give up compared to selecting individual stocks yourself.
This guide covers all three dimensions: what the ETF structure actually holds, how the performance and cost numbers stack up, and a practical framework for deciding whether the Indian defense ETF route, direct stock picking, or a combination of both fits where you are as an investor.
What the Indian defense ETF actually is and how it works
Both MODEFENCE and Groww’s defense ETF are passive funds that track the Nifty India Defence Total Return Index. Neither fund’s managers make active decisions about which defense companies to buy or sell; they simply replicate the index’s composition and weightings. The TRI version of the benchmark matters because it assumes dividend reinvestment, which produces a slightly higher return than a price-only index, a detail worth keeping in mind when comparing reported fund performance against other benchmarks.
Fund basics and expense ratio
MODEFENCE launched on August 21, 2024, with NSE listing on August 27, 2024. As of September 30, 2026, it carries an AUM of approximately ₹1,358 crore, a NAV of ₹101.85, and a defense ETF expense ratio (TER) of 0.62%. The Groww Nifty India Defence ETF runs with an AUM of ₹368 crore, a NAV of ₹92.68, and a TER of 0.64%. Neither fund has a three-year performance history, which is a meaningful limitation when assessing how these products behave across different market cycles, including the inevitable drawdown phases that hit sector-specific themes.
Tracking error and liquidity
One technical advantage MODEFENCE holds is tracking error: the fund reported a tracking error of 0.04% versus the benchmark in 2026, compared to 0.11% for Groww’s ETF. For a passive fund, tighter tracking is a quality indicator, a wider tracking error means your actual returns will consistently differ from what the index delivered. Liquidity is also reasonable: MODEFENCE averaged approximately 1.4 to 1.6 million units traded daily on NSE, with a bid-ask spread of roughly ₹0.05 per unit, which translates to about 0.05% of the unit price.
What the performance numbers actually tell you
The headline numbers look impressive. Groww’s defense ETF reported a one-year return of 30.90% and a since-inception return of 23.35% as of August 31, 2026. MODEFENCE reported a one-year return of 18.27% and a since-inception return of 13.98% as of September 30, 2026. The gap between those two figures is almost entirely explained by the difference in measurement dates, not by portfolio quality or manager decisions, they track the same index. Over the comparable period, the Nifty 50 TRI delivered approximately -0.35% on a one-year basis, making the defense theme’s outperformance look dramatic.
That outperformance is real, but context matters. Both funds launched in August 2024, which placed their inception near the beginning of a strong defense-sector upcycle. Sector-specific runs are, by definition, cyclical. An ETF that launched at the trough of a cycle will show exceptional since-inception returns; one that launches near a peak will show the opposite. With less than two years of data, neither fund’s track record is long enough to draw confident conclusions about how it will behave through a full market cycle.
Fee impact over time
The cost drag compounds quietly. A 0.62% to 0.64% TER is notably high for a passive ETF. Broad Nifty 50 ETFs typically charge between 0.05% and 0.20%. Over a 10-year holding period, a fee difference of 0.40 to 0.55 percentage points per year takes a meaningful bite out of compounded returns. Add the bid-ask spread on each transaction and tracking error, and your real cost of ownership runs somewhat higher than the stated expense ratio alone suggests. For investors comparing Indian defense ETF options against broad-market sector ETFs in India, this cost differential deserves serious weight.
The concentration problem hiding inside the index
The Nifty India Defence Index sounds like a diversified basket, but the actual portfolio construction tells a different story. In MODEFENCE, the top four holdings account for nearly two-thirds of total assets:
- HAL at approximately 21%
- Bharat Electronics (BEL) at roughly 20%
- Solar Industries around 15%
- Bharat Forge near 8%
The remaining exposure is spread across Mazagon Dock, Bharat Dynamics, Cochin Shipyard, Garden Reach Shipbuilders, MTAR Technologies, Data Patterns, Astra Microwave, Zen Technologies, and a handful of smaller names. Buying this Indian defense ETF is not a diversified portfolio decision; it is effectively a concentrated bet on HAL and BEL with some adjacency exposure.
The purity of the defense theme is also worth scrutinizing. Bharat Forge is primarily a global auto-components supplier with a growing defense vertical, not a pure-play defense company. Solar Industries is fundamentally an explosives and chemicals manufacturer; its defense business is one segment of a much broader industrial operation. If your investment thesis is specifically about India’s military modernization and procurement indigenization, a meaningful portion of what this ETF holds is only partially aligned with that thesis. You’re buying the label along with exposure that doesn’t fully match it.
Why the Indian defense ETF route still makes sense for some investors
For investors who don’t have the time or inclination to read quarterly results, analyze order-book coverage ratios, and track promoter holding changes across multiple companies, the ETF provides a clean, low-overhead allocation to the defense theme. You avoid stock-selection risk, you don’t need to monitor individual company fundamentals every quarter, and you don’t have to decide how to rebalance your defense holdings as relative valuations shift over time. The ETF handles all of that automatically through passive index replication.
There’s also a genuine tax efficiency advantage when you consider the alternative. Rebalancing a five-stock or ten-stock direct defense portfolio means selling individual positions that have run, which triggers capital gains events each time. For listed equity ETFs that qualify as equity-oriented funds, the same 12.5% long-term capital gains rate applies on gains above ₹1.25 lakh annually as for direct stocks, but internal index rebalancing within the ETF doesn’t create a taxable event for you as a unitholder. That structural benefit is real, especially for active rebalancers.
If your defense allocation is a smaller, tactical slice of a larger diversified portfolio, say, below 5 to 10% of your total equity exposure, the ETF format makes practical sense. You get the thematic exposure without the portfolio management overhead, and you can access it via any demat account with no minimum investment beyond a single unit’s market price.
When direct stock picking beats the defense ETF
The alpha case for individual stock selection in Indian defense is straightforward: if you’re willing to do the analytical work, you can build a more precise portfolio than the index offers. You can concentrate in the highest-conviction names, avoid holdings whose defense revenue is diluted by unrelated business lines, and size positions based on your actual view of each company’s fundamentals relative to its current valuation. Several individual defense stocks have outperformed the broader Nifty India Defence Index on an annualized basis since the index’s July 2018 inception, which means selective stock pickers have had real opportunities to generate returns above what the Indian defense ETF captures.
The ETF’s biggest structural disadvantage is that it buys the index regardless of valuation. In a momentum-driven sector like Indian defense, the index constituents can get expensive quickly during an upcycle. When you hold the ETF, you have no mechanism to avoid paying peak multiples for a constituent that has already priced in years of growth, or to wait for a better entry on a high-quality name after a temporary price correction. Direct stock picking restores that optionality: you can be selective about what you buy and when, rather than owning the entire basket at whatever price the momentum has driven it to.
This is precisely the use case where deep fundamental research becomes your edge. Breaking down Zen Technologies’ order book composition, understanding what Data Patterns’ bid pipeline signals about its forward revenue, walking through BEL’s quarterly margin trajectory, that kind of analysis is what enables conviction-based position sizing rather than passive index replication. Detailed stock-level research on defense companies serves exactly that investor profile: someone who wants to go beyond the ETF and build a more precise portfolio based on company-specific fundamentals rather than index weights.
How to decide which approach fits your investment goals
The decision between an Indian Defence ETF and direct stock picking isn’t ideological; it’s practical. Your answer should depend on three variables: how much time you’re willing to invest in ongoing research, how large your defense allocation is as a share of your total portfolio, and how comfortable you are with company-specific analysis. Neither approach is universally superior, they serve different investor profiles at different stages.
Choose the defense ETF if your defense allocation is below 5 to 10% of your portfolio, if you’re in the earlier stages of building your fundamental analysis skills, or if you simply want clean thematic exposure without a sustained research commitment. The ETF delivers the theme with minimal effort, reasonable liquidity, and adequate tracking quality, making it a solid baseline for investors who are newer to sector ETFs in India.
Consider direct stock picking if you already follow individual defense companies, understand how order-book-to-revenue conversion works, and have formed a view on which index constituents offer the strongest long-term fundamentals at their current valuations. The most productive approach for many investors is actually a hybrid: start with an ETF allocation to establish baseline exposure, then gradually build direct positions in the highest-conviction names as your research depth increases. That progression, from index-level exposure toward company-level precision, is exactly what structured fundamental analysis enables.
Final thoughts: low effort isn’t the same as best outcome
The Indian Defence ETF isn’t a bad product. It’s a well-constructed passive vehicle for a genuine structural investment theme, with reasonable liquidity, tight tracking error (particularly for MODEFENCE), and a simple investment process. For many retail investors, it’s the right starting point.
But the concentration in two or three large positions, the above-average expense ratio for a passive fund, the limited track record, and the absence of valuation discipline in index construction are real trade-offs. Treating the ETF as a permanent answer rather than a starting point means accepting all of those limitations indefinitely. The investors who get the most out of India’s defense investment cycle will be those who combine the ETF’s thematic accessibility with a growing ability to evaluate individual companies on their fundamentals, order books, balance sheets, and management execution track records.
Whether you take the ETF route, build a direct stock portfolio, or run both in parallel, the foundation is the same: you need to understand what you own and why you own it. Thematic exposure without that understanding is just momentum chasing with an extra step. Start with the research, then size the position accordingly.
