How Many Defence PSU Stocks Should Be in Your Portfolio?

You Want Indian Defence Stocks — But How Many Is Too Many?

You have seen the headlines. Indian defence stocks have been among the best performers on the stock market over the past three years. HAL, BEL, Bharat Dynamics, Mazagon Dock — these names have delivered 200 to 500 percent returns. Naturally, you want in. But here is the question most investors skip: how many defence PSU stocks should you actually own?

The answer is a specific number, and the math behind it matters more than your excitement about the sector.

The Right Number: 2 to 4 Indian Defence Stocks

For most retail investors, 2 to 4 defence PSU stocks is the right range. Owning more than 4 gives you very little extra diversification. Owning just 1 concentrates too much risk in a single company.

Why this range? Because the Indian defence PSU universe is small and highly correlated. There are only about 15 to 18 listed defence PSUs. Many of them move together because they share the same customer (the Indian government), the same budget cycle, and the same policy tailwinds.

After 3 to 4 well-chosen stocks, adding more defence names barely reduces your sector risk. You are just spreading the same bet thinner.

How Much of Your Portfolio Should Be in Defence?

This is equally important. Defence is a sector bet, and sector bets should be sized carefully.

Notice the pattern. As your portfolio grows, you should actually reduce your percentage in any single sector. Larger portfolios need more diversification, not more concentration.

Never put more than 15 percent of your portfolio in defence stocks. This is a sector driven by government orders and policy decisions. One budget cut, one change in procurement policy, and the entire sector can correct 30 to 40 percent.

Which Defence PSU Stocks to Pick

If you are picking 2 to 4 stocks, you want to cover different segments of the defence value chain. Here is how to think about it:

1. A large cap anchor. HAL (Hindustan Aeronautics) or BEL (Bharat Electronics) should be your first pick. These are the most liquid, most diversified defence PSUs. HAL dominates aerospace. BEL dominates electronics and radar systems. Pick one or both.
2. A shipyard player. Mazagon Dock or Cochin Shipyard gives you exposure to naval defence. India is investing heavily in indigenous warship and submarine building. This is a different revenue stream from HAL or BEL.
3. A missile or ammunition specialist. Bharat Dynamics (missiles) or Munitions India gives you exposure to weapons systems. These companies have strong order books and long-term government contracts.
4. An optional fourth pick. BEML (defence vehicles), Garden Reach Shipbuilders, or Hindustan Shipyard. Only add a fourth if you have done deep research and have a specific reason.

Why Indian Defence Stocks Are Attractive Right Now

The bull case for defence is strong and structural:

• India's defence budget has crossed 6.2 lakh crore rupees for 2025-26. It grows 8 to 12 percent every year.
• Self-reliance push. The government now mandates that a large share of defence equipment must be made in India. This directly benefits domestic PSUs.
• Export growth. Indian defence exports have grown from 1,500 crore rupees in 2017 to over 21,000 crore rupees in 2024. Countries like Philippines, Malaysia, and Armenia are buying Indian weapons systems.
• Order books are massive. HAL has an order book of over 1 lakh crore rupees. BEL has over 76,000 crore rupees. These provide revenue visibility for 4 to 5 years ahead.

You can track defence procurement updates on the NSE India website through corporate filings.

The Risks You Must Understand

Defence stocks are not risk-free. Far from it.

• Order execution delays. Government orders are large but often delayed by years. Revenue recognition can be lumpy and unpredictable.
• Valuation risk. After the recent rally, many defence PSUs trade at 40 to 60 times earnings. These are historically expensive levels for PSU stocks.
• Single customer risk. The Indian government is the primary customer for most defence PSUs. A budget cut or policy shift affects every company in the sector simultaneously.
• Political risk. Defence procurement is deeply political. Changes in government can alter priorities and timelines.

The biggest risk with defence stocks is not the sector itself. It is your allocation. Too much in one sector — any sector — turns a good investment into a dangerous gamble.

A Practical Portfolio Example

Here is what a well-constructed defence allocation looks like inside a 20 lakh rupee portfolio:

1. HAL — 1 lakh rupees (5 percent of portfolio)
2. BEL — 80,000 rupees (4 percent of portfolio)
3. Mazagon Dock — 60,000 rupees (3 percent of portfolio)

Total defence allocation: 2.4 lakh rupees (12 percent). Three stocks covering aerospace, electronics, and shipbuilding. Different revenue streams but the same macro tailwind. The remaining 88 percent of your portfolio should be in other sectors, index funds, or debt instruments.

Should You Buy Now or Wait?

After the massive run-up, entering defence stocks at current valuations requires patience. Consider starting a SIP-style approach — invest a fixed amount every month over 6 to 12 months. This averages out your entry price and reduces the risk of buying at peak valuations.

Defence is a strong long-term theme. But your allocation matters more than your stock picks. Keep it to 2 to 4 stocks, cap it at 15 percent of your portfolio, and you will be positioned to benefit from India's defence growth without putting your entire portfolio at risk.
