Defence Stocks Surge Up to 37% After Operation Sindoor: What’s Next?

Defence Stocks: How ‘Operation Sindoor’ Redefined India’s Military-Industrial Complex

The Indian equity markets have long been sensitive to geopolitical shifts, but few events in recent history have catalyzed the defense sector as profoundly as Operation Sindoor. On the night of May 6–7, 2025, India executed a series of precision military strikes on terrorist infrastructure in Pakistan and Pakistan-administered Kashmir. While the operation secured strategic objectives on the ground, its ripples in the financial district of Dalal Street were equally transformative.

One year later, as of May 6, 2026, the data paints a picture of a sector in the midst of a historic bull run. Indian defense stocks have delivered returns of up to 37%, swelling the sector’s market capitalization by a staggering ₹2.9 lakh crore. This growth is not merely a “war rally” but a fundamental re-rating of the sector, fueled by record-breaking budgets, emergency procurement mandates, and an aggressive pivot toward Atmanirbharta (self-reliance).

The ‘Sindoor’ Effect: A Year of Exponential Growth

According to reports from Outlook Business, the twelve months following the Pahalgam attack and the subsequent retaliatory strikes have been the most lucrative in the history of Indian defense investing. The Nifty India Defence Index, the primary benchmark for the sector, has reflected this optimism with a one-year annualized return of 34.07% as of early May 2026.

Dr. Manoranjan Sharma, Chief Economist at Infomerics Valuation and Ratings, notes that the success of Operation Sindoor was an “unequivocal validation” of India’s technological self-reliance. The reliance on indigenous platforms during the strikes—ranging from HAL-manufactured aircraft to BEL’s electronic warfare systems—convinced investors that “Made in India” was no longer just a slogan but a combat-proven reality.

The Eight-Day Surge: Immediate Market Reflexes

The initial reaction to the military action was explosive. Within just eight trading sessions following the commencement of Operation Sindoor in May 2025, defense shares rallied between 15% and 40%. Investors correctly anticipated that the government would immediately loosen its purse strings for emergency procurements to replenish stocks and enhance border surveillance.

• Cochin Shipyard: Led the pack with a 40% gain in eight days.

• Bharat Dynamics (BDL): Rose 27% as demand for anti-tank and surface-to-air missiles spiked.

• Hindustan Aeronautics (HAL): Surged to an intraday high of ₹5,110 (a 5% jump in a single session).

• Bharat Electronics (BEL): Climbed to ₹365.70 as orders for radar and communication systems poured in.

2025: The Year the Titans Rose

While the initial rally was driven by sentiment, the sustained growth throughout the 2025 calendar year was driven by balance sheets. The year 2025 became a “Goldilocks period” for Public Sector Undertakings (PSUs) and private players alike.

1. Garden Reach Shipbuilders: Emerged as the standout performer of 2025, delivering 79% returns.

2. Paras Defence: A favorite in the niche space of optics and electronics, it yielded 61%.

3. The Big Three (HAL, BEL, BDL): These heavyweights saw gains of 15%, 40%, and 61%, respectively, proving that even large-cap stocks could deliver mid-cap-style growth under the right tailwinds.

Beyond the military operation, three external factors acted as multipliers:

• The India-US Defense Framework Agreement: Opening doors for high-tech co-development.

• India-Russia Joint Manufacturing: Strengthening the supply chain for military components.

• DAC Approvals: A streamlined Defense Acquisition Council provided a consistent pipeline of multi-billion dollar contracts.

Breaking Records: Exports and Production in FY25

The government’s push for indigenization yielded tangible results in the financial year ending March 2025. India’s defense exports hit a record ₹23,622 crore, a staggering 34-fold increase compared to the ₹686 crore recorded in FY14. This 12.04% year-on-year growth signaled that Indian defense products were becoming competitive on the global stage, particularly in Southeast Asia, Africa, and the Middle East.

Furthermore, total domestic defense production crossed the ₹1.5 lakh crore mark in FY25. For investors, this indicated that the “order book-to-execution” cycle was accelerating, leading to improved cash flows and better margins for listed entities.

The FY27 Budget: A War Chest for the Future

The Union Budget presented on February 1, 2026, served as the ultimate catalyst for the “Sindoor Rally.” The Ministry of Defence received a record allocation of ₹7.85 lakh crore for FY27—a 15.19% increase over the previous year.

Key Budgetary Highlights:

• Capital Outlay: ₹2.19 lakh crore (up 21.8%) earmarked for the purchase of new weapons, aircraft, and warships.

• Emergency Procurements: Approximately ₹40,000 crore was retroactively accounted for post-Sindoor, covering drones, precision ammunition, and loitering munitions.

• Aviation Boost: A 31% increase in the ‘Aircraft and Aero-engines’ category, directly benefiting HAL and its ecosystem of suppliers.

• Naval Fleet: ₹25,023 crore allocated for the modernization of the Navy.

• High-Altitude Warfare: Over ₹82,000 crore set aside for digitization, sensors, and equipment specialized for the rugged terrain of the LAC and LOC.

The Outlier: MTAR Technologies

While the PSUs grabbed the headlines, MTAR Technologies redefined the limits of sectoral growth. Specializing in precision engineering for aerospace, nuclear, and defense, MTAR saw its stock price skyrocket by 337.76% in the year following Operation Sindoor. Its ability to provide mission-critical components for both the defense and clean energy sectors made it a darling of institutional investors looking for high-growth “multibaggers.”

Strategic Benchmark: Nifty India Defence Index

For the broader market, the Nifty India Defence Index has become the barometer of national security sentiment. Dominated by free-float giants like Solar Industries India, Bharat Forge, Mazagon Dock, and the aforementioned PSUs, the index has shown remarkable resilience.

As of the March 30, 2026, factsheet, the index boasted a 5-year CAGR of 28.03%. However, the “Sindoor Rally” accelerated this significantly in the following month, with the index trading at a Price-to-Earnings (P/E) ratio of 45.72. While some analysts suggest this valuation is “frothy,” others argue that the visibility of earnings over the next decade justifies the premium.

Looking Toward 2047: The Long-Term Horizon

The trajectory of Indian defense stocks is no longer tied to sporadic border skirmishes. A joint report by the CII and KPMG India suggests a structural shift that will span decades.

• Budgetary Projection: The defense budget is expected to swell from ₹6.81 lakh crore (FY26) to ₹31.7 lakh crore by 2047.

• Production Growth: Domestic production is estimated to grow sixfold to reach ₹8.8 lakh crore.

• Export Ambition: India aims to export ₹2.8 lakh crore worth of military hardware by 2047, a 12x increase from current levels.

Conclusion: What to Expect Next

The one-year anniversary of Operation Sindoor marks a turning point. We have moved from a phase of “anticipatory buying” to “performance-led growth.” Investors should expect:

1. Consolidation in Large Caps: After the massive run-up, stocks like HAL and BEL may enter a period of time-correction as markets wait for quarterly earnings to catch up with valuations.

2. Focus on “Deep Tech”: Companies specializing in AI-driven surveillance, drone swarms, and electronic warfare (like Paras Defence and Zen Technologies) are likely to see increased interest.

3. Supply Chain Integration: As India moves toward manufacturing engines and advanced composites locally, the sub-tier suppliers will likely become the next frontier for high returns.

Operation Sindoor was a testament to India’s military resolve; for the markets, it was the spark that ignited a decade-long structural bull market in defense. As the nation marches toward its centenary in 2047, the defense sector stands as a cornerstone of both national security and investor portfolios.
