Defense Industry: Investing Essentials

It's always a brave new world for the defense industry. Here's what you need to know to invest in it.

The Iraq War is history. The war in Afghanistan is winding down. And with the wind-down, a lot of investors may be thinking that the defense industry is "history" too.

But here's the thing: History repeats itself. We're seeing that in Iraq right now, as the ISIS spreads mayhem across the Mideast. Meanwhile, to the north, Russia has proven itself newly aggressive in Ukraine and Crimea, while to the east, a rising China is flexing its muscles -- and pushing to impose its will on its neighbors.

In short, it's a dangerous world out there, Fools. So long as it remains so, there will be a future for the defense industry. Here's what you need to know to invest in it.

What is the defense industry?

A subsector of the aerospace and defense industry, the defense industry in particular focuses on large-cap corporations (and in many foreign countries, state-owned enterprises) whose primary customers are nation-states, and whose primary products are military hardware and services. Depending on the company, these may include:

  • Military aircraft (everything from F-16 fighter jets to B-2 stealth bombers to combat helicopters to new-fangled unmanned aerial vehicles)
  • Warships (submarines, destroyers, aircraft carriers)
  • Ground defense (tanks, APCs, and guns both big and small)
  • Ammunition for all of the above (rockets, missiles, bullets, cannon and howitzer rounds)
  • Military satellites and also dual-use satellites (such as surveillance satellites, America's Global Positioning Satellite constellations, and their European "Galileo" and Russian "Glonass" counterparts)
  • The rockets that put those satellites in orbit, and the engines that power those rockets

The complex electronics systems and software products that permit all of the above to operate correctly, electronic warfare systems such as radar -- and radar-jamming -- and software and hardware components of both "cybersecurity" and "cyber warfare" also fall under the category of defense products and services.

How big is the defense industry?

Defense is big business in the United States, with the defense budget consuming approximately 20% of the federal budget in recent years. Globally, the U.S. accounts for about 41% of worldwide defense spending.

But that still leaves nearly 60% of global defense spending to account for. Consulting firm Deloitte estimates that the next five biggest markets for defense products are China, France, Japan, Russia, and the U.K. -- accounting for 23% of global defense expenditures combined. The next 19% of global defense dollars go to the militaries of Australia, Brazil, Canada, Germany, India, Israel, Italy, Saudi Arabia, South Korea, and Turkey.

Defense spending as a percentage of the global whole drops steeply from there, but all-in, the global market for defense products tops $1.72 trillion annually -- and makes up as much as 85% of the total value of the global aerospace and defense market as a whole.

How does the defense industry work?

Excellent question. Clearly, defense is the proverbial 800-pound gorilla of the aerospace and defense market, accounting for the vast majority of spending in its parent industry. So understanding how this money gets spent is crucial for investors in defense.

The good news for investors is that defense spending is an unusually "transparent" market, in which it's easy to track the broad ebb and flow of revenues over time. This is because most countries publish, and make easily available, information on their planned defense budgets ahead of time -- often, years ahead of time.

Data on U.S. defense spending, such as is laid out in the table above, is just one example. You can find similar reports on anticipated defense expenditures in "white papers" published by the Australian government, in public announcements by the Russian Ministry of Defense and the Japanese Prime Minister. Even nominally communist China publishes a defense budget. (Although there's quite a bit of disagreement about how forthcoming China is in the information it contains).

Once the budget is set, the governments in question typically hold tenders, inviting bids from local and foreign defense contractors, to provide the products and services they require. A winning bid is accepted and, typically, the winner is announced.

Caveat: One wrinkle that investors should be aware of is that most major defense contracts awarded in the West these days may name a single winner. But the firm that "wins" the contract and is named the "principal contractor," rarely does all the work itself. No sooner does a firm win a contract than it turns around and parcels out much of the work to other defense contractors. (Indeed, oftentimes defense companies bid as a "team" from the get-go).

The result is that no matter who wins a contract, as often as not, "everyone" in the industry tends to benefit.

What drives the defense industry?

As with most industries, you can say that the defense industry is driven by two primary factors: risk and opportunity. It's just that the defense industry has its own peculiar take on the definitions of these terms.

From a risk standpoint, the more dangerous the world, the more nation-states perceive a need to spend money on defense. The country that spends the single greatest percentage of its GDP on its military, for example (10.3%), is one currently involved in an on-again, off-again civil war: South Sudan. The next three top spenders (again, as a percentage of GDP) all reside in the turbulent Middle Eastern neighborhood: Oman, Saudi Arabia, and Israel.

But opportunity also plays a role. The United States, for example, the single greatest spender on defense in absolute dollar value, is protected by wide oceans to both east and west, and has inoffensive neighbors to both north and south. Yet as one of the world's wealthiest nations, the United States still spends freely on defense -- enough to make it the No. 1 defense market globally by a wide margin. Meanwhile, a surging economy and valuable oil reserves combine with numerous, sometimes aggressive neighbors to make China and Russia, respectively, the No. 2 and No. 3 defense markets in the world.

Simply put, therefore, defense spending is likely to increase both when nation states think they need to spend more on their militaries -- and also just because they can.

Caveat: The wrinkle investors want to be aware of here is that defense spending by defense companies' host countries may ebb and flow. But the companies are not limited to their host countries' markets. As defense spending has trended down globally in recent years (dropping 1.9% in 2011, then 1.3% in 2012, followed by an estimated 2.5% decline in 2013 according to Deloitte), defense companies are more and more often looking to new markets abroad to shore up their revenue streams.

Where will they go to find the defense contracts that will fill up their revenue streams? Turn to your nearest newspaper headline to find out. Wherever conflict is, there will the defense industry go to find new markets for its products.

To be perfectly clear, this is not a get-rich action that my Foolish colleagues and I came up with. But we wouldn't argue with the approach.

A 2015 Business Insider article titled, "11 websites to bookmark if you want to get rich" rated The Motley Fool as the #1 place online to get smarter about investing.

"The Motley Fool aims to build a strong investment community, which it does by providing a variety of resources: the website, books, a newspaper column, a radio [show], and [newsletters]," wrote (the clearly insightful and talented) money reporter Kathleen Elkins. "This site has something for every type of investor, from basic lessons for beginners to investing commentary on mutual funds, stock sectors, and value for the more advanced."

Our mission at The Motley Fool is to help the world invest better, so it's nice to receive that kind of recognition. It lets us know we're doing our job.

Whether that's helping the entirely uninitiated overcome their fear of stocks all the way to offering clear and successful guidance on complicated-sounding options trades, we want to provide our readers with a boost to the next step on their journey to financial independence.

As Business Insider wrote, there are a number of resources available from the Fool for investors of all levels and styles.

In addition to the dozens of free articles we publish every day on our website, I want to highlight two must-see spots in your tour of

For the beginning investor

Investing can seem like a Big Deal to those who have yet to buy their first stock. Many investment professionals try to infuse the conversation with jargon in order to deter individual investors from tackling it on their own (and to justify their often sky-high fees).

But the individual investor can beat the market. The real secret to investing is that it doesn't take tons of money, endless hours, or super-secret formulas that only experts possess.

That's why we created a best-selling guide that walks investors-to-be through everything they need to know to get started. And because we're so dedicated to our mission, we've made that available for free.

If you're just starting out (or want to help out someone who is), go to, drop in your email address, and you'll be able to instantly access the quick-read guide ... for free.

Whether it's on the stationary exercise bike or during my daily commute, I spend a lot of time going nowhere. But I've found a way to make that time benefit me.

David Gardner, co-founder of The Motley Fool, is among the most respected and trusted sources on investing. And he's the host of Rule Breaker Investing, in which he shares his insights into today's most innovative and disruptive companies ... and how to profit from them.

Market Foolery is our daily look at stocks in the news, as well as the top business and investing stories.

And Industry Focus offers a deeper dive into a specific industry and the stories making headlines. Healthcare, technology, energy, consumer goods, and other industries take turns in the spotlight.

They're all informative, entertaining, and eminently listenable ... and I don't say that simply because the hosts all sit within a Nerf-gun shot of my desk. Rule Breaker Investing and Answers contain timeless advice, so you might want to go back to the beginning with those. The other three take their cues from the market, so you'll want to listen to the most recent first. All are available at
