5 defence stocks to arm your portfolio

Defence stocks are not generally considered to be "defensive stocks."

Investment professionals will usually define defensive stocks as those with steady and predictable earnings, competitive advantages that prevent rivals gaining a foothold in their sector, a strong balance sheet and a relatively stable share price. But in reality, what’s considered “defensive” is whatever held up best in the last market sell-off.

In behavioural science this is called recency bias. It causes nervous investors to rush for what they wish they had owned in the last bear market, regardless of whether those companies are well placed for the current one. If market declines are brief enough, the very belief that a company is defensive can help it resist price falls and bolster its defensive reputation.

But when bear markets drag on long enough, actual operating results dictate share-price performance, and some erstwhile defensives prove anything but. Similarly, a new crop of companies emerge that demonstrate the attributes listed above.

As contrarian investors, we are always looking for attractively-priced companies with under-appreciated defensiveness. Often these are in industries that have inherently defensive characteristics and used to be considered defensive, but have recently fallen out of favour. Sometimes real negative change has occurred, and industries may never regain their defensive status.

Telecoms companies are a good example. The world has changed: they no longer dominate the flow of global information and they have to fight with more competitors for a pie that is shrinking owing to technology-driven efficiencies. When was the last time you placed a long-distance phone call?

However, sometimes our research supports the idea that a formerly defensive industry still deserves to trade at a premium defensive valuation, even if it isn’t highly valued right now. We believe defence stocks fall into that category.

Defence stocks jump as China and Russia flex their muscles

Certain defence stocks attracted attention over a year ago, with interest sparked by two developments. Firstly, it was becoming clear that China’s and Russia’s geopolitical assertiveness and military build-up was more secular than cyclical, and that it would spark a similar response from those feeling threatened – as it has since the time of Thucydides.

Secondly, shares that were already inexpensive owing to years of falling defence budgets were, in the case of European companies, being pushed down even harder owing to the announcement of a new EU social taxonomy, which promised to increase the cost of doing business for companies whose activities don’t contribute to the social goals of the EU. Defence stocks were initially considered among the worst offenders.

In November of 1989, the Berlin Wall fell and the Cold War ended. With that, defence budgets dropped precipitously, as the West sought to cash in the peace dividend. As the chart below shows, defence spending settled at very low levels for many countries, eclipsed by other social priorities. The vast majority of Nato countries are still below the Nato requirement to spend at least 2% of GDP on defence.

With Russia’s second invasion of Ukraine and China’s increasingly strident stance towards Taiwan, the peace dividend is now clearly eliminated. Some are saying we’re entering a new Cold War, but for Russia and China, it actually never ended, and the profit-driven and optimistic West has been caught underprepared and underinvested in its deterrence against potential aggression.

Russia’s invasion of Ukraine on 24 February ended the period of political rationalisation that followed its 2014 annexation of Crimea. In response, nearly every European country has announced a massive increase in defence budgets. These increases come in ways that signal a long-term shift in attitude, with increases in military force, long-term weapons programmes, and in the case of Germany, Sweden, and Finland, historic changes in their stance towards war.

A crucial sea change

We do not believe that Wall Street analysts are even close to increasing adequately their earnings estimates to account for the coming torrent of defence spending.

Looking at the chart, it is easy to see why. After more than 30 years of dropping revenues, it is incredibly difficult for those covering defence stocks to register the full impact of the change we’re seeing today, or they are assuming what we’re currently experiencing is merely a brief spike.

We disagree. We don’t see an imminent Russian defeat or Putin disappearing, we don’t see China turning away from its regional goals, and we don’t see any sort of worldwide consensus to support the Western powers’ opposition to Russia. In fact, we think it more likely that the world will return to a mix of East and West blocs, and unaligned nations.

This is a recipe for significantly increased defence budgets that then grow steadily off that higher level, not just in Europe but also throughout the world. Korea, Japan, Australia and India have all recently announced increased spending on defence.

That has not gone completely unnoticed by the market, and our defence stocks Saab (Stockholm: SAAB-B), BAE Systems (LSE: BAE), Thales (Paris: HO), Rheinmetall (Frankfurt: RHMD), and Mitsubishi Heavy Industries (Tokyo: 7011) are all up by 30%-60% so far this year, growing from small positions to represent over 5% of the portfolio.

Yet we believe they still have considerable upside. Saab AB makes the Gripen fighter jet, a highly capable and lower-cost alternative to Lockheed’s F-35, which is overbooked on orders, forcing countries to look for alternatives. The Swedish company also makes the NLAW, an anti-tank weapon now in huge demand following its successful use by Ukrainian forces.

BAE makes frigates, submarines, and the Typhoon fighter, all highly sought after, as well as the M777 howitzers recently supplied by the US to Ukraine.

Thales, Rheinmetall, and Mitsubishi Heavy Industries have all been inundated with enquires about their hardware.

Defence stocks will profit as government spending grows

For all five companies, earnings expectations for 2025 have increased, but only modestly – by 10%-15% for BAE, Saab, and Thales, 30% for Mitsubishi Heavy Industries, and 60% for Rheinmetall (driven by Germany’s €100bn increase in defence spending). Following those revisions, the defence stocks now sell at a discount to the market on forward price/earnings, but we believe both the “p” and the “e” should change. On the earnings side, if our assessment of an intensified and protracted Cold War is correct, considerable increases in earnings expectations are likely.

On the price side, we see two compelling cases for higher valuations. Firstly, Russia’s invasion has spurred commentators on environmental, social, and governance (ESG) to rethink their negativity towards the defence industry. Some continue to view contractors as producing equipment that is used to kill people and destroy societies. But other ESG advocates now see the industry as providing the means for societies, especially those that are most aligned with ESG principles, to deter would-be attackers.

For free societies, a healthy advanced defence sector is something they need to have, not something they should just want to have, and recent events have made that obvious even to former critics of the industry. As more clear-eyed views of the sector prevail, this should remove a cloud over defence stocks’ valuations.

Secondly, and more importantly, the defence contractors we hold are fundamentally defensive businesses. Most of their contracts are protected against inflation, and all but Rheinmetall have been less volatile than world stockmarkets over the long term. As those defensive characteristics come to be better appreciated, these firms should warrant a premium price. In a volatile and inflationary world, the real “defensives” may be in defence.
