The Nifty India Defence Index has returned 30.6% in the 12 months since the April 22, 2025, Pahalgam terror attack nearly three times the Nifty 50’s 10.8% gain over the same period, according to NSE index data. The index’s top performer is Data Patterns (India) Ltd, whose stock has risen approximately 76%, from around ₹2,000 in April 2025 to ₹3,526 as of April 21, 2026 (NSE closing price), driven by a record order book of ₹1,868 crore as of December 31, 2025, as disclosed in the company’s Q3 FY26 earnings filing dated February 6, 2026.

What Drove the Rally: Budget Numbers, Not Just Sentiment
The Pahalgam attack accelerated a spending shift already underway. In the Union Budget announced February 1, 2026, the Ministry of Defence received its highest-ever allocation of ₹7.85 lakh crore for FY2026-27, a 15.2% increase over the previous year’s estimate of ₹6.81 lakh crore, according to official Union Budget 2026-27 documents. Capital outlay, the portion that directly funds procurement of new platforms and weapons, rose 21.8% to ₹2.19 lakh crore from ₹1.80 lakh crore in FY26, per the same documents.
Of that ₹2.19 lakh crore capital budget, ₹1.39 lakh crore (75%) is reserved for domestic defense manufacturers, up from 40% a decade ago, according to the Ministry of Defence and analysis by the Manohar Parrikar Institute for Defence Studies and Analyses (MP-IDSA). That structural shift in procurement policy — domestic share nearly doubling in ten years — is what has sustained the sector’s re-rating beyond the initial Pahalgam shock.

Stock by Stock: Who Earned the Gain and Who Is Running on Valuation
Data Patterns (India) Ltd — the standout private player
Data Patterns has delivered the index’s highest 1-year return at approximately 76%. The Chennai-based defence electronics company reported Q3 FY26 revenue of ₹173 crore, up 48% year-on-year, and net profit of ₹58 crore, up 31% YoY, per the company’s earnings release dated February 6, 2026. Its order book reached an all-time high of ₹1,868 crore as of December 31, 2025 — equivalent to roughly 2.6 times FY25 full-year revenue — providing strong near-term visibility. The company has guided for 20–25% revenue growth over the next two to three years, per its Q3 FY26 earnings call.
The catch is structural: defence electronics revenue is inherently lumpy because it is tied to project milestones, not monthly shipments. In Q2 FY26, Data Patterns revenue was ₹307 crore. In Q3 FY26, it fell 44% sequentially to ₹173 crore, per company filings — not a business deterioration, but a reflection of milestone-based revenue recognition. Investors who evaluate this stock on its annual return alone are missing material intra-year volatility.
Bharat Electronics Ltd (BEL) — strong fundamentals, stretched valuation
BEL’s stock gained approximately 11% over the year modest against the index, but underpinned by the cohort’s strongest earnings delivery. The company reported FY26 provisional turnover of ₹26,750 crore, a 16.2% year-on-year increase from ₹23,024 crore in FY25, per a BEL exchange filing dated April 1, 2026. Its order book as of April 1, 2026 stands at ₹74,000 crore nearly 2.8 years of revenue at the current run rate. Export sales grew 33.65% to $141.9 million in FY26 from $106.17 million in FY25, per the same filing.
The valuation problem is quantifiable. BEL’s trailing price-to-earnings ratio stands at approximately 54x as of April 2026, according to StockAnalysis.com, against a 10-year historical average of 23.18x per Wisesheets data. BEL is currently trading at a 133% premium to its own long-run average multiple. At 54x P/E, the stock requires earnings to grow at roughly 20% or more annually for three consecutive years before reaching a normalised multiple. In the first nine months of FY26, BEL’s net profit grew approximately 21% — ₹3,845 crore versus ₹3,183 crore in the same period a year prior, per Q3 FY26 company filings. That growth rate meets the bar but only barely, and with no margin for the kind of supply chain disruption that hit HAL in the same year.
Hindustan Aeronautics Ltd (HAL) — order book of ₹2.54 lakh crore, revenue grew 4.1%
HAL’s +4% return is the weakest among the index’s major constituents, and the reason is explicitly stated in its own filings. The company reported FY26 provisional revenue of ₹32,250 crore, up just 4.1% from ₹30,981 crore in FY25, per an HAL exchange filing dated April 2026. HAL directly cited delays in the LCA Mk1A and HTT-40 programmes due to “geopolitical and technical supply chain issues” as the primary constraint. Meanwhile, its order book grew to ₹2.54 lakh crore per the same filing. An order book of ₹2.54 lakh crore generating only 4.1% revenue growth gives a book-to-revenue ratio of approximately 7.9x. That ratio signals execution capacity, not order flow, as the binding constraint for FY27.
The Retail Concentration Risk Nobody Is Talking About
Motilal Oswal’s Nifty India Defence Index Fund the primary passive vehicle for retail exposure to the sector carried an AUM of approximately ₹3,697 crore as of April 21, 2026, per Paytm Money. Its 1-year return of 33.5% has driven significant retail inflows. What most investors in this fund do not realise: BEL accounts for 28.18% of the index by free-float market capitalisation, and HAL for 24.42%, per the NSE index factsheet dated April 15, 2026. A fund that is 52.6% concentrated in two PSU stocks both trading at multi-year valuation highs, both with disclosed execution risks is not the sector diversification its marketing implies.
The Valuation Gap: What the Numbers Require to Hold
The sector’s structural tailwinds are real and sourced. Domestic procurement’s share of the capital acquisition budget has risen from 40% in FY2020-21 to 75% in FY2026-27, per MP-IDSA. India’s defence budget has grown from ₹4.85 lakh crore in FY21 to ₹7.85 lakh crore in FY27 — a 62% increase in six years, per Union Budget documents. These are enacted allocations, not projections.
But earnings have not kept pace with valuations across the cohort. BEL trades at 54x trailing earnings versus a 10-year average of 23x. Mazagon Dock and Zen Technologies trade between 50–61x P/E, per market data as of April 2026. The arithmetic at 54x P/E is specific and answerable: BEL needs to grow earnings at approximately 20% annually for three years to reach a 33x multiple still a premium to its historical average at current prices. FY26’s 21% net profit growth rate meets that bar. HAL’s 4.1% revenue growth does not. The risk is not uniform across the index; it is concentrated in the two stocks that together make up 52.6% of the flagship retail fund.
Quantified Risk Factors
- BEL valuation premium: Trading at 54x TTM P/E vs 10-year average of 23.18x — 133% above long-run mean (StockAnalysis.com / Wisesheets)
- HAL execution gap: ₹2.54 lakh crore order book produced only 4.1% revenue growth in FY26 due to LCA Mk1A and HTT-40 supply chain delays (HAL exchange filing, April 2026)
- Fund concentration: Motilal Oswal Defence Fund is 52.6% in BEL + HAL (28.18% + 24.42%) despite diversified positioning (NSE factsheet, April 15, 2026)
- Data Patterns lumpiness: Revenue fell 44% sequentially Q2→Q3 FY26 (₹307 crore to ₹173 crore) due to milestone-based recognition (company filings)

Frequently Asked Questions
Why have India defence stocks risen so much after the Pahalgam attack?
The April 22, 2025, Pahalgam attack triggered both immediate re-pricing of military risk and a durable acceleration in procurement spending. The FY27 Union Budget, announced February 1, 2026, allocated ₹2.19 lakh crore in capital outlay a 21.8% increase over the prior year with 75% reserved for domestic manufacturers, up from 40% in FY2020-21, per Union Budget 2026-27 documents and MP-IDSA analysis. The rally is backed by enacted budget policy, not speculation.
Which India defence stock has performed best in the last 12 months?
Data Patterns (India) Ltd has returned approximately 76% in the 12 months to April 22, 2026 the highest among major Nifty India Defence Index constituents. This is driven by Q3 FY26 revenue growth of 48% YoY to ₹173 crore and a record order book of ₹1,868 crore as of December 2025, equivalent to 2.6 times FY25 full-year revenue, per the company’s earnings release dated February 6, 2026.
Is BEL a good buy after the 2025–26 defence rally?
BEL’s fundamentals are solid: ₹26,750 crore FY26 revenue (+16.2% YoY), ₹74,000 crore order book, and export growth of 33.65% to $141.9 million, per BEL’s exchange filing dated April 1, 2026. However, at a trailing P/E of approximately 54x versus its 10-year historical average of 23.18x (StockAnalysis.com / Wisesheets), the stock requires sustained 20%+ annual earnings growth for three years to justify current prices at a normalised multiple. FY26 nine-month profit growth of 21% meets that bar currently, but leaves no room for slippage. Consult a SEBI-registered financial adviser before acting.
What is the risk of investing in defence mutual funds in India?
The Motilal Oswal Nifty India Defence Index Fund (AUM: ₹3,697 crore as of April 21, 2026, per Paytm Money) allocates 28.18% to BEL and 24.42% to HAL making it over 52% concentrated in two PSU stocks, both trading significantly above their historical average P/E multiples, per the NSE index factsheet dated April 15, 2026. Investors are taking on concentrated single-sector and valuation risk, not broad defence diversification.
Why did HAL underperform despite a massive order book?
HAL’s FY26 revenue grew only 4.1% to ₹32,250 crore despite an order book of ₹2.54 lakh crore because deliveries of the LCA Mk1A and HTT-40 aircraft programmes were delayed by geopolitical and technical supply chain disruptions, as stated explicitly in HAL’s April 2026 exchange filing. An order book records future contracts, not current delivery capacity. HAL’s order-book-to-revenue ratio of approximately 7.9x indicates that execution, not order flow, is the binding constraint going into FY27.
