DCO vs HXL: Which Is the Better Buy in 2026?
Last updated October 2026
Short answer
HXL is the larger of the two ($6.82B market cap): the incumbent the market prices for continued execution (28.67x forward earnings, beta 1.10). DCO is the smaller challenger ($2.58B), priced similarly on forward earnings (31.82x): more room to run, but more to prove. The real question is which set of drivers you believe, and whether owning one (or both) leaves you over-concentrated.
DCO vs HXL: the tie-breaker metrics
Same yardstick, side by side (as of October 2026). Valuation lined up like this is most meaningful for two names in the same corner of the market, which these are. Figures are approximate; verify before investing.
| Metric | DCO | HXL | What it tells you |
|---|---|---|---|
| Market cap | $2.58B | $6.82B | Size. The larger name is the incumbent; the smaller has more room to grow and more to prove. |
| Forward P/E | 31.82 | 28.67 | Valuation on next year's expected earnings, the same yardstick for both. Lower is cheaper for that growth; higher means the market is paying up. |
| Beta | 1.04 | 1.10 | Volatility vs the market. Above 1 swings harder than the index; below 1 is steadier. Higher beta means bigger drawdowns to hold through. |
| Price vs 52-week range | 68% of range | 58% of range | Where today's price sits between the 52-week low and high. Near the high is momentum with less margin of safety; near the low is out of favor or a discount, depending on why. |
| Price / book | 3.73 | 5.25 | How much you pay over book value. Very high can signal an asset-light, high-return business or a rich price. |
Before you buy: how DCO and HXL affect your concentration
The metrics above tell you which is the marginally better business. The bigger risk for most people is not picking the slightly worse stock, it is over-concentrating. DCO and HXL share themes, so owning both, or adding either to what you already hold, can quietly push a large share of your portfolio into one bet.
This is the part a generic comparison page cannot answer, because it depends on what you own. Connect your brokerage and Walnut shows your real, combined DCO and HXL exposure, flags overlap with your existing positions, and tells you if adding one would tip you past a concentration you are comfortable with, read-only by default, with your login staying at your broker.

What does Ducommun (DCO) do?
Ducommun Incorporated is a Santa Ana, California supplier of engineered products and manufacturing services to aerospace and defense customers. It runs two segments. Electronic Systems, the larger one at roughly 58% of second-quarter 2026 revenue, makes circuit card assemblies, wire harnesses and cable, radar and microwave subsystems, and printed circuit boards for missiles, radar, avionics and space hardware. Structural Systems makes metal and composite airframe structures, engine components and titanium parts. The company is one of the oldest continuously operating businesses in California, founded in 1849, and it sits a tier below the primes: it sells to Raytheon, Lockheed Martin, Boeing, Airbus, Northrop Grumman, Spirit AeroSystems and the engine makers rather than to governments or airlines directly. A deliberate shift over the past few years has been toward proprietary engineered products and aftermarket work, which reached about 23% of revenue over the trailing year versus roughly 15% in 2022.
What does Hexcel (HXL) do?
Hexcel is a leading maker of advanced composite materials, primarily carbon fiber and engineered composite structures used to make products lighter and stronger. Its core market is commercial aerospace, where its carbon fiber, reinforcement fabrics, resins, and honeycomb materials go into aircraft wings, fuselages, engine components, and interiors for planes like the Boeing 787 and Airbus A350 and A320 family. Hexcel also serves space and defense (missiles, satellites, military aircraft, rotorcraft) and select industrial markets such as wind energy and high-performance automotive. The company makes money by supplying these specialized materials, often qualified into specific aircraft programs over many years, which creates high switching costs and recurring demand tied to aircraft production rates. Because composites reduce weight and improve fuel efficiency, their content per aircraft has grown over successive generations of planes. Revenue was roughly flat at about $1.9 billion in both 2024 and 2025, then picked up in 2026: quarterly sales rose from $456 million in the September 2025 quarter to $529 million in the June 2026 quarter. Founded in 1948 and headquartered in Stamford, Connecticut, with about 5,600 employees, Hexcel is a focused, high-quality materials supplier closely tied to the commercial aerospace cycle.
DCO vs HXL: how do they differ?
Both fit overlapping themes, but they are not interchangeable. The useful comparison is which set of drivers and risks you want exposure to.
- DCO drivers: Missile and defense electronics demand; The commercial narrowbody rate ramp.
- HXL drivers: Rising composite content per aircraft; Commercial aerospace recovery.
Which fits which kind of investor
A faster-growing, richer-valued name usually swings harder, so it suits a longer horizon and a higher tolerance for volatility; a steadier, more cash-generative business suits a more conservative or income-minded investor. The honest test is which set of risks you could hold through a drawdown: Program concentration is the structural risk: a handful of platforms (the 737 MAX, the A320, PAC-3, SM-6, the F-15) drive a large share of revenue, and Ducommun does not control the build rates on any of them. For HXL, hexcel is concentrated in commercial aerospace and dependent on Boeing and Airbus build rates, so any production slowdown, program delay, or downturn in air travel directly hurts demand.
DCO or HXL: which should you pick?
Growth-minded investors who believe the theme has years to run tend to accept the richer multiple for more upside; value-minded investors lean toward the cheaper forward earnings and steadier profile. Pick DCO if you believe its drivers more; HXL if you believe its. Many investors hold both, but since they share themes, that is a concentrated bet, not diversification. Decide deliberately and check overlap. For the full detail, see the DCO and HXL guides.
DCO vs HXL: the full fundamentals
DCO. Ducommun is priced like a defense electronics grower rather than a build-to-print machine shop, at about 32x forward earnings and 22x EV to EBITDA. Trailing GAAP earnings are negative because of a large third-quarter 2025 charge, so the forward estimate of about $5.37 for 2027 carries the valuation. The shares sit about 19% below their 52-week high and below the average analyst target near $220, with the November 5 quarter the next test.
HXL. As of October 16, 2026, Hexcel trades near 46x trailing and 29x forward earnings, a gap that shows how much of the valuation rests on the expected recovery in earnings as aircraft build rates climb. The stock is up about 18% year to date and 49% over a year but down 16% over three months. Third-quarter results arrive on October 21, with consensus EPS around $0.50 on about $502 million of revenue, and the multiple remains sensitive to Boeing and Airbus production news.
Headline figures (approximate, October 2026): DCO shows revenue (ttm) ~$865 million, q2 2026 revenue / adjusted eps ~$224.5 million (+~12% yoy) / $1.18 vs ~$0.98 expected, margins (ttm) Gross ~27.4%, operating ~12.6%, adjusted ebitda margin (q2 2026) ~17.1%, versus the ~18% Vision 2027 target; HXL shows revenue (ttm) ~$2.0 billion, revenue growth (latest quarter, yoy) ~8%, operating margin ~14%, net income (ttm) ~$154 million.
The bottom line: DCO vs HXL
DCO and HXL are related but distinct: same themes, different businesses and risks. Neither wins in the abstract; the right pick is whichever thesis you actually believe, sized so you are not over-concentrated in one theme. Walnut can show your combined DCO and HXL exposure against your real portfolio. It is not an investment adviser.

FAQ
What is the difference between DCO and HXL?
+
Ducommun Incorporated is a Santa Ana, California supplier of engineered products and manufacturing services to aerospace and defense customers. Hexcel is a leading maker of advanced composite materials, primarily carbon fiber and engineered composite structures used to make products lighter and stronger. They show up together because they share investment themes, but they are different businesses, so the better fit depends on which thesis you are expressing.
Is DCO or HXL the better stock?
+
Neither is universally better. HXL is the larger incumbent; DCO is the smaller challenger and looks pricier on forward earnings. Walnut is informational, not investment advice. Compare what each does, the tie-breaker metrics above, and the risks, then decide which fits your thesis and what you already own.
Which is cheaper, DCO or HXL?
+
On forward P/E (as of October 2026), DCO trades at 31.82x and HXL at 28.67x, so HXL is the cheaper of the two on next year's expected earnings. A lower multiple is not automatically the better buy: a richer valuation can be justified by faster growth, and a lower one can reflect real risk. Weigh the multiple against how fast each business is compounding.
Should you own both DCO and HXL?
+
Because they share themes, owning both concentrates you in that theme. That can be intentional (a focused bet) or accidental (less diversification than it looks). Walnut can show your combined exposure across both, and whether adding either over-concentrates you, before you buy.
What are the risks of DCO vs HXL?
+
DCO: Program concentration is the structural risk: a handful of platforms (the 737 MAX, the A320, PAC-3, SM-6, the F-15) drive a large share of revenue, and Ducommun does not control the build rates on any of them. Its customer list is short and includes Boeing, whose production has been unsteady, so a rate cut, a strike or a program termination flows straight through. The accounting is a live issue: the company said in May 2026 that its 2024 and 2025 statements should no longer be relied upon because of a stock-based compensation timing error, restated them, disclosed a material weakness in internal control over financial reporting, and at least two plaintiffs' firms opened investigations, which raises the odds of litigation and of further remediation cost. Defense revenue depends on appropriations and on continued urgency around munitions restocking, both of which are political rather than commercial variables. Trailing GAAP results show a net loss of about $21 million, largely from a third-quarter 2025 charge, and operating cash flow was slightly negative over the trailing year, so the earnings recovery still has to show up in cash. Larger acquisitions under Vision 2032 would add integration and leverage risk. Finally, at roughly $2.6 billion of market value on about $865 million of sales and about 32x forward earnings, the shares already price the Vision 2027 margin outcome, so a missed quarter on Structural Systems or a slip in the margin trajectory has more room to hurt than to help. HXL: Hexcel is concentrated in commercial aerospace and dependent on Boeing and Airbus build rates, so any production slowdown, program delay, or downturn in air travel directly hurts demand. The pandemic showed how sharply aircraft production and Hexcel's revenue can fall in a shock. The business is capital intensive, so weak volumes leave high fixed costs underutilized and compress margins; trailing net margin was only about 7.8% as of mid-2026. Customer concentration is significant, and the qualification of competing materials or shifts in aircraft programs are risks. Energy and raw-material costs affect carbon fiber production. The stock can be volatile and carries a valuation (about 46x trailing earnings as of October 2026) that requires a strong aerospace ramp to justify. Sentiment has cooled ahead of third-quarter results: Morgan Stanley cut its target to $97 from $110 and RBC to $105 from $115 in mid-October, and the shares sit well below their 52-week high of about $112.
