Best defense stocks: how to pick them with discipline

To identify the best defense stocks, start with business quality before price. The first thing is the order backlog: how many years of sales are signed in advance. A company with a backlog of 2.5 times its annual sales has visible revenue that other industries would envy. Also look at the book-to-bill ratio: if new contracts signed exceed those delivered (ratio greater than 1), the backlog grows and the business expands.

Second, assess the moat. Ask yourself: is this program hard to take away from the company? Defense systems with sky-high switching costs — where replacing the supplier would force retraining, recertifying and redoing the logistics — are the most defensible. Third, look at the return on invested capital, or ROIC: a business that sustainably generates a ROIC above its cost of capital is creating real value, not just booking revenue. At DeepTicker, all of this is summed up in the DeepTicker Score, a 0-100 quality grade scoring five dimensions (Valuation, Growth, Track record, Profitability and Solvency) by comparing each company with its sector, so you don't compare an aircraft maker with a bank.

Beyond the backlog, there are figures that tell the real health of a defense company. Cash conversion is crucial: because many contracts are paid by milestone, you should look at free cash flow and not just accounting profit. A healthy business converts a good part of its profit into real cash. Debt also weighs: large programs require investment, so watch the net debt to EBITDA ratio; below 2.5x-3x usually indicates a comfortable financial structure in this sector.

For quality, observe the operating margins and their stability across the cycle (defense companies usually run at 10%-15% operating, with the aftermarket lifting the average). For valuation, instead of trusting a loose P/E, DeepTicker uses the Reverse DCF (discounted-cash-flow valuation): instead of asserting 'this stock is worth $X', it calculates what growth and what margin the current price is pricing in and lets you judge whether you believe it. For example, if a contractor historically grows 5%-6% a year but the price is only justified by assuming a sustained 10% over ten years, you know the market is being demanding. And the cost of capital is taken from the real WACC by industry (from public data), not a generic one, which can change the estimated value by 15%-30%.

The big risk is political and budgetary. Although long-term government contracts provide stability, the ultimate customer is the State, and defense budgets depend on elections, priorities and public debt. A change of government, a peace deal or a fiscal cut can freeze programs. Customer concentration makes this worse: if most of the revenue comes from a single government or from one large program, the company is exposed to a single decision.

There are more layers. There's execution risk: large programs run late and over budget, and fixed-price contracts can eat into the margin if costs spiral. There's regulatory and export risk, because selling weapons abroad depends on permits that can be denied. And there's a reputational and ethical risk specific to the sector that you should take on consciously: many funds with ESG criteria exclude defense, which can affect demand for the stock. Finally, don't forget the valuation risk: buying a wonderful company at a bubble price is still a bad idea, no matter how wide its moat.

Reviewing each contractor by hand is slow. That's why the efficient way to find quality defense stocks is to filter with data using a screener. With DeepTicker's stock screener (more than 140 filters and ready-made strategy presets, like Graham or the Magic Formula) you can narrow the universe in seconds: companies in the industrial/aerospace-defense sector with high ROIC, controlled debt, stable margins and positive revenue growth. In a couple of clicks you go from hundreds of names to a short, manageable list of candidates that deserve study.

Filtering isn't the end, but the start of the analysis. Once you have the short list, enter the stock pages of each one: there you see the DeepTicker Score (quality by sector), the Reverse DCF (whether it's expensive or cheap today) and the data behind every number, because DeepTicker isn't a black box: it shows you how it's calculated. That way you combine defense stocks with good fundamentals and a reasonable price, instead of buying on headlines. And the more you use the tool, the more you learn to judge for yourself, which is the real goal.

The most common mistake when investing in defense is assuming that a good business is always a good investment. They're different things. Quality answers 'is the company good?' (moat, ROIC, backlog, solvency); price answers 'is it expensive or cheap TODAY?'. A leading contractor with a decades-wide moat can be a magnificent business and still trade at a price that prices in barely credible growth. Overpaying for the best company in the sector can leave you years without a return.

This is where value analysis helps: the EPV estimates the value of current earnings without assuming growth, only with what it earns today on a sustainable basis, and compares it with what it would cost to replicate; if the former is greater, there's a real franchise. And it applies a simple mathematical rule: if the growth implied in the price exceeds the cost of capital (G ≥ R) persistently, the price is hardly sustainable, a 'priced-in miracle'. Bringing together the three questions — quality (DeepTicker Score), price (Reverse DCF) and franchise (EPV) — gives you a complete picture that no headline will give you. DeepTicker applies widely recognized fundamental-analysis methods from public data.
