Following Operation Sindoor, Indian defence stocks have experienced a significant surge, with the Nifty India Defence Index notably outperforming the broader Nifty 50. This surge reflects renewed investor confidence and heightened interest in the Indian defence sector, spurred by the operation's success and the government's ongoing emphasis on indigenous defence manufacturing.

Operation Sindoor, executed in early May 2025, involved targeted strikes against terrorist infrastructures in Pakistan, responding to a prior attack on tourists in Kashmir. The operation showcased India's advanced military capabilities, particularly in drone combat, air defence, and electronic warfare, bolstering investor sentiment towards homegrown defence firms. Market experts view the operation as a catalyst, demonstrating the seamless integration of indigenous systems into national defence.

Several factors contribute to the bullish outlook for Indian defence stocks. Government initiatives like the 'Make in India' campaign, coupled with increased defence budgets, are playing a crucial role. These initiatives encourage indigenous design, development, and manufacture of defence equipment, reducing reliance on imports and fostering self-reliance. The government's support extends to policy reforms and a focus on boosting defence exports, further propelling the sector's growth.

The Nifty India Defence Index has risen sharply since May 7, 2025, with many individual stocks within the sector posting substantial gains. Companies such as Garden Reach Shipbuilders & Engineers Ltd (GRSE), Cochin Shipyard Ltd, Mishra Dhatu Nigam Ltd (MIDHANI), and Bharat Dynamics Ltd (BDL) have witnessed significant rallies, outperforming broader market indices. Small-cap stocks like Astra Microwave Products and Paras Defence and Space Technologies have also seen considerable increases.

Analysts anticipate a rerating of defence stocks, citing strong growth prospects and policy support. Big-ticket orders, including submarines and naval warships, are expected to be placed in the near future, potentially tripling the order books of listed defence shipyards. This positive outlook is further reinforced by expectations of aggressive execution targets for defence companies, leading to increased revenues and earnings over the long term.

However, experts advise a cautious approach amid investor enthusiasm, highlighting potential overvaluation risks. Geopolitical tensions and market volatility may also impact the sector's performance in the short term. Nonetheless, the long-term prospects for Indian defence stocks remain promising, driven by government support, indigenous manufacturing capabilities, and a growing focus on exports.

The success of Operation Sindoor has not only boosted investor confidence but has also highlighted the competence of Indian defence products. The operation demonstrated India's ability to apply military power with precision and restraint, signaling resolve and deterring cross-border terrorism. This has redefined the contours of India's response toolkit and positioned the country as a credible player in the global defence arena.
