Key takeaways
- Defense budgets are trending higher: Geopolitical tensions across multiple regions are pushing governments to spend more on defense, and that spending isn’t discretionary anymore. This creates a durable demand backdrop for companies across the sector, from aircraft manufacturers to nuclear technology providers.
- Diverse business models reduce concentration risk: The strongest names in this group aren’t one-trick ponies. They span commercial aviation, government services, advanced materials, and nuclear propulsion, which means they can capture growth from multiple spending streams rather than relying on a single contract or program.
- Valuations have already moved significantly: A lot of the good news is priced in across the sector, with many defense stocks trading at premium multiples compared to their historical averages. If geopolitical tensions de-escalate or government budgets face austerity pressure, these stretched valuations could snap back quickly, so entry points matter a lot right now.
Defense spending globally is going in one direction: up. That’s not a prediction. It’s a trend that’s been building for years and accelerated sharply as geopolitical conflicts pile up across multiple regions simultaneously. NATO allies are under real pressure to hit their spending targets, and the U.S. defense budget continues to climb. For investors, the question isn’t whether money is flowing into this sector. It clearly is. The question is which companies are positioned to actually capture it.
I find this sector fascinating because the revenue dynamics are so different from what most investors are used to. Long-term government contracts provide visibility that you just don’t get in consumer-facing businesses. When a defense company has a multi-year backlog worth billions, that’s not a hope. It’s signed work. That kind of predictability is rare, and it tends to get undervalued by a market obsessed with quarterly beats.
The flip side? Not every company in this space is a winner. Some are bloated prime contractors with margin pressure. Others are burning cash chasing futuristic concepts that may never generate revenue. The spread between the best and worst operators is enormous. I wanted to focus on names where the growth story is backed by real financial performance, or where a specific catalyst could change the trajectory meaningfully. That’s the GARP filter I always come back to, whether I’m looking at U.S. tech stocks or defense names.
What caught my attention with this group is the range. You’ve got a proven compounder in Heico that’s been quietly delivering for decades. Mercury Systems is a turnaround story with real execution risk. And Archer Aviation is a pre-revenue bet on a technology that could reshape urban air mobility, or amount to nothing. Three very different risk profiles, three very different investment theses.
If you’re a Canadian investor looking to add U.S. exposure beyond the usual mega caps, defense is a sector where the macro tailwinds are about as strong as they get. The names below sit at different points on the risk spectrum, so your appetite for volatility matters a lot here.

Defense is one of the few sectors where the macro setup and the micro fundamentals are actually aligned right now. Government budgets are expanding, backlogs are growing, and the political will to spend more on defense exists across both parties in the U.S. and across NATO. That doesn’t mean you can buy blindly. The valuation spread across these three names tells you that the market is already pricing a lot of good news into certain corners of this space, while treating others with deep skepticism.
I keep coming back to one question with each of these: what does the company look like in five years if defense spending simply stays where it is today? Not if it doubles. Not if some new conflict breaks out. Just if current budgets hold. The answers you get from that exercise are very different depending on the name, and that’s where your conviction should come from.
