Up 25% in a Month: Are Defence Mutual Funds Still a Buy or is it Time to Wait?

What Are Defence Mutual Funds?

Defence mutual funds are thematic or sectoral equity funds that invest primarily in companies deriving significant revenues from India's defence ecosystem.

This includes:

• Aerospace and aviation manufacturers (HAL, MTAR Technologies)

• Defence electronics and systems (Bharat Electronics, Data Patterns)

• Shipbuilding and naval platforms (Mazagon Dock, Garden Reach, Cochin Shipyard)

• Explosives and propulsion (Solar Industries India, Bharat Dynamics)

• Engineering and components (Bharat Forge, Astra Microwave)

Most defence funds in India track the Nifty India Defence Index, comprising 18 constituent companies selected based on free-float market capitalisation.

The Macro Story Behind the Recent Surge

Before we move on to the performance and other details about defence funds, let's understand the macro story and why this is a structural shift in the making.

1. India's Defence Budget

   India's commitment to modernising its armed forces is not a short-term policy whim. The numbers speak plainly:

   Fiscal Year	Total Defence Budget	Capital Expenditure	YoY Growth
   FY2013-14	Rs 2.53 lakh crore	-	-
   FY2021-22	Rs 4.78 lakh crore	Rs 1.35 lakh crore	9%
   FY2024-25	Rs 6.21 lakh crore	Rs 1.72 lakh crore	6%
   FY2025-26 (Current)	Rs 6.81 lakh crore	Rs 1.80 lakh crore	9.5%
   FY2047 (Projected)	Rs 31.7 lakh crore (est.)	Rs 10 lakh crore (est.)	~5x from FY26

   The FY26 budget of Rs 6.81 tn marks a 2.7x growth since FY14. More crucially, 75% of the capital procurement budget is now ring-fenced for purchases from Indian companies. This indigenisation mandate is the direct revenue tailwind for the stocks inside these funds.

2. Defence Exports: From Negligible to Record-Breaking

   Nothing captures India's industrial ambition in defence better than its export growth:

   Year	Exports (Rs crore)	YoY Growth
   FY2013-14	Rs 686 crore	-
   FY2017-18	Rs 4,682 crore	30%
   FY2021-22	Rs 12,815 crore	54%
   FY2024-25	Rs 23,622 crore	12%
   By 2029 (Target)	Rs 50,000 crore	-

   India now exports defence equipment to over 85 countries, compared to fewer than 20 a decade ago.

   The government's target of Rs 500 bn in exports by 2029 is ambitious but increasingly credible, validated by record order books at HAL, BEL, and Solar Industries.

3. Operation Sindoor & Geopolitical Catalysts

   In April-May 2025, India launched Operation Sindoor, a precision military strike against nine terrorist camps in Pakistan and Pakistan-Occupied J&K, following the Pahalgam terror attack.

   The operation was a demonstration of India's precision strike capabilities using indigenously developed weapons and platforms.

   The immediate market response was a sharp 7% weekly rally in the Nifty India Defence Index, far outstripping the flat performance of Nifty 50 in the same period.

   Additionally, three strategic deals compounded the sentiment:

   • India-US 10-year Defence Framework Agreement: Technology sharing, intelligence cooperation, and joint production.

   • India-Russia joint manufacturing MoU: Maintenance, spare parts, and co-production of Russian-origin hardware in India.

   • Record FY25 order flow: The Ministry of Defence signed 193 contracts worth Rs2.1 tn, the highest on record, with 92% going to domestic companies.

4. Order Book Visibility

   Earnings visibility in defence is unusually high because of multi-year contract structures. The total domestic contract pipeline stands at close to Rs 4 tn over the next 5 to 7 years.

Historical Performance: How has the Index Really Done?

Before we assess the current opportunity, it is worth grounding ourselves in the full historical record of the Nifty India Defence TRI versus the broader market.

The pattern is clear. This is an index capable of explosive returns, and equally sharp reversals.

The Nifty India Defence TRI has delivered 20%+ CAGR in over 90% of rolling 3-year periods since its base date.

But the index also suffered painful drawdowns of 40-50% during those same cycles.

Should You Buy Defence Mutual Funds?

The honest answer to this question is that it depends on your time horizon, allocation discipline, and whether you can stomach a 30-40% drawdown without panic-selling.

For a long-term investor willing to invest for 5-7 years, the structural story is compelling.

However, one must note that major defence stocks are trading at expensive valuations.

While they carry a structural premium, the gap is unusually wide. This is not necessarily a worrying signal, but the margin of safety is thin for near-term investors, and any earnings miss or policy disappointment could trigger a sharp de-rating.

Key Risks to Understand

SEBI categorises all defence mutual funds as 'Very High Risk'.

Concentration risk is the most significant. The Nifty India Defence Index has only 18 constituents, a single adverse government procurement decision, order cancellation, or earnings miss can disproportionately impact the entire fund.

Policy dependency is equally important. Defence contracts are government-to-government and heavily bureaucratic.

Any slowdown in the Defence Acquisition Council's approvals, a change in the indigenisation mandate, or a shift in foreign policy that reduces threat perception can rapidly cool investor sentiment.

India in the Global Context: The Worldwide Defence Boom

The bull case for Indian defence funds is not isolated, it sits within a broader global re-armament trend.

NATO nations have committed to raising defence spending above 2% of GDP. US defence contractors are benefiting from replenishment demand after Iran and Ukraine conflicts drew down munitions stockpiles.

Japan has doubled its defence budget to 2% of GDP for the first time since World War II. Germany has lifted its constitutional spending cap on defence. South Korea and Australia are among the fastest-growing new defence spenders globally.

India's defence sector is additionally unique in that it is growing both as a buyer (modernisation) and as a seller (exports). This two-sided growth driver gives Indian defence companies a compounding earnings advantage that few global peers enjoy.

Conclusion

After analysing the macro data, fund performance, valuations, and risk-reward, here's what the data suggests.

The Indian defence story is real, policy-backed, and export-powered. SIP investors with a 5 to 7-year horizon can consider these funds.

The recent 25% monthly surge is a momentum event layered on a legitimate structural story. These are not mutually exclusive, but they do mean that the easy money has already been made.

The second leg of returns, if it comes, will be earned through patience and discipline, not through chasing last month's returns.

India is genuinely becoming a defence manufacturing powerhouse. The budget allocations, the export trajectory, the indigenisation push, and the geopolitical environment all point in the same direction.

Defence mutual funds offer the most accessible way to participate in this theme, but they must be held with clear position sizing, a long time horizon, and an unwavering awareness that this is a high-risk, high-conviction play.

Happy investing.
