NEW YORK, Dec. 28, 2025, 12:59 p.m. ET — Market closed
U.S. stock exchanges are shut for the weekend, leaving space and defense investors to parse a dense batch of late-week headlines and year-end macro signals before trading resumes Monday morning. The New York Stock Exchange’s core trading session runs 9:30 a.m. to 4:00 p.m. ET, meaning the next real “price discovery” window for aerospace and defense names arrives with Monday’s open—likely in thin, end-of-year liquidity where headlines can move stocks faster than fundamentals. [1]
That thin-liquidity backdrop is important: Wall Street ended Friday’s post-Christmas session nearly unchanged and near record levels, with the “Santa Claus rally” period still underway, according to Reuters. Market strategist Ryan Detrick of Carson Group told Reuters the market was “catching our breath” after a strong run, while noting the seasonal tendency for an upward bias through early January. [2]
For space and defense stocks, the weekend setup is less about earnings (still weeks away for most) and more about geopolitics, procurement signals, and how investors rotate capital into industrials and “real-economy” winners as 2025 closes out. Reuters’ week-ahead preview highlighted an S&P 500 hovering near a psychological milestone and investors watching rotation beyond mega-cap tech—conditions that can either amplify defense’s “steady cash-flow + backlog” appeal or punish anything that looks over-owned into year-end.

The last 48 hours: the headlines that matter for defense and space stocks
1) China sanctions U.S. defense firms over Taiwan arms sales
Late Friday, China’s foreign ministry announced sanctions on 20 U.S. defense firms and 10 individuals, including Boeing’s St. Louis branch, and units tied to Northrop Grumman and L3Harris, in response to U.S. arms sales to Taiwan, according to Reuters. The report notes the move freezes assets held in China and bans domestic organizations and individuals from doing business with the listed entities—though Reuters also emphasized the action appears largely symbolic given China’s limited dealings with U.S. defense contractors. [4]
Why investors care: even “symbolic” sanctions can create Monday-morning volatility—especially in a low-volume tape—because they touch the sector’s two biggest narrative drivers:
- Great-power competition (which tends to support higher defense spending over time), and
- Cross-border exposure (where Boeing’s commercial aviation footprint in China gets scrutinized whenever geopolitics heats up). [5]
2) Europe’s rearmament narrative gets another data point
Reuters reported the UK and Germany signed a $70 million joint deal for mobile artillery systems, a reminder that European procurement is still moving even as diplomacy and peace-talk headlines ebb and flow. While U.S. investors often default to the big American primes, European defense demand increasingly matters for globally exposed suppliers, munitions makers, and subsystems providers. [6]
3) Ukraine peace-plan diplomacy is back in focus
Over the weekend, Reuters reported Ukrainian President Volodymyr Zelenskiy planned to meet U.S. President Donald Trump in Florida to discuss a plan to end the war in Ukraine, following heavy Russian strikes and ongoing debate over territorial issues. Markets tend to translate such headlines into a simple question: does the conflict look longer (usually supportive for defense procurement urgency) or does it look like it could freeze (which can pressure some European defense names in particular)? [7]
4) Blue Origin makes a national-security push with a headline hire
In space—and especially “defense space”—Reuters reported that Blue Origin hired longtime ULA CEO Tory Bruno as president of a newly formed national security-focused unit, underscoring its push to compete for U.S. military and intelligence launch work. Bruno’s move also highlights the tight interconnections in the launch industrial base: Blue Origin supplies BE-4 engines used on ULA’s Vulcan rocket, even as it competes for the same national security launch opportunities. [8]
Why investors care: Blue Origin is private, but shifts in competitive pressure influence how investors think about the public ecosystem—Boeing (which co-owns ULA with Lockheed), defense primes bidding on space architectures, and public “space hardware” players that sell spacecraft components, structures, avionics, or satellite buses.
5) China signals support for commercial space capital formation
Reuters also reported China eased IPO rules for firms developing reusable rockets, an indicator of Beijing’s intent to deepen its commercial space bench and accelerate competition in launch and related supply chains. While this doesn’t directly price into U.S.-listed defense primes overnight, it adds to a broader theme: launch and space infrastructure are becoming strategic industries, not just venture stories. [9]
The market backdrop: why Monday could be “headline-sensitive” for aerospace & defense
The setup into Monday is unusual in a familiar way: year-end markets often look calm on the surface, but with fewer participants and more portfolio housekeeping, individual names can gap sharply on news. Reuters’ Friday market wrap described a light-volume session with limited catalysts, and flagged how trading volumes can exaggerate moves. [10]
In Reuters’ week-ahead preview, multiple strategists emphasized that momentum remains with the bulls while investors watch for evidence of rotation beyond technology and for clarity on interest-rate expectations—factors that matter for defense and space stocks because they sit at the crossroads of industrials, government spending, and (for space) growth-stock duration risk. [11]
Wall Street’s “big idea” on defense into 2026: value, backlog, and a changing threat picture
Even before this weekend’s geopolitical newsflow, large investors were already leaning into a 2026 defense thesis: the sector may still look attractively priced relative to its growth visibility.
- Morgan Stanley’s defense view: In a note summarized by Investing.com, analyst Kristine Liwag said the firm sees U.S. defense stocks as providing “good value,” arguing prices aren’t fully reflecting defense budget growth. Morgan Stanley upgraded L3Harris and General Dynamics to Overweight, downgraded Lockheed Martin to Equal-weight, and kept Northrop Grumman as a top pick, according to the same report. [12]
- ETF strategist picks: Business Insider reported that Scott Helfstein, senior vice president of investment strategy at Global X ETFs, expects defense to have room to run in 2026 amid what he described as “decentralized deterrence” and higher policy uncertainty. In the same piece, Helfstein highlighted five names he likes heading into 2026: Huntington Ingalls (HII), BAE Systems (BAESY), Rheinmetall (RNMBY), Lockheed Martin (LMT), and BWX Technologies (BWXT). [13]
The implication for Monday: in a market where investors are watching “rotation” and valuation discipline, defense can trade like a quality-industrials group—until a headline (sanctions, budgets, peace talks, new awards) forces a rapid repricing.
Fundamentals check: what “backlog” looks like in practice
One reason big defense names often act defensively in volatile markets is the visibility created by multi-year programs and long-cycle service revenue. A concrete example: in an RTX filing on the SEC’s EDGAR system, the company reported company backlog of $251 billion, including $103 billion of defense, alongside comments from CEO Chris Calio pointing to robust global demand and new awards supporting long-term growth. [14]
That backlog concept is central to how many portfolio managers size positions in the sector: when macro uncertainty rises, high-backlog primes can look like “bond proxies with catalysts”—but unlike bonds, they’re still equity risk, and they can gap on policy or geopolitical shocks.
Boeing’s defense program spotlight: Congress vs. Pentagon priorities
Another late-week development with potential read-throughs is the ongoing debate around major airborne and space-based surveillance architectures. A Wall Street Journal report described Congress stepping in to support the U.S. Air Force’s Wedgetail radar plane program despite Pentagon skepticism and cost overruns, including a per-jet figure cited at $724 million and additional funding for prototypes in the broader defense policy package. [15]
For investors, the takeaways aren’t only about one airframe. It’s about a recurring theme in defense equities:
- Congressional support can extend or reshape programs even when the Pentagon signals ambivalence.
- The future mix of airborne vs. space-based sensing remains a live debate—one that matters for defense primes, avionics suppliers, and “defense space” architectures.
Space stocks: defense demand is the stabilizer, launches are the accelerant
Public “space stocks” often trade with higher volatility than legacy defense primes because many are still scaling manufacturing, launching new platforms, or proving margins. But defense-related demand—especially satellite architectures and national security launch—has increasingly acted as a stabilizer.
One high-profile example came earlier in December: Investors.com reported Needham analyst Ryan Koontz raised Rocket Lab’s price target and highlighted the company’s positioning in government defense, including a large Space Development Agency-related opportunity discussed in the same report. [16]
Now add this weekend’s Reuters headline that Blue Origin is building a dedicated national-security unit under a veteran launch executive, and you have a competitive environment where:
- Launch cadence and reliability can change investor sentiment quickly,
- Government procurement pathways (multi-vendor awards, tranche-based architectures) can produce step-function revenue visibility, and
- Any shift in national security strategy can ripple through primes and smaller space suppliers alike. [17]
What investors should know before Monday’s session
With the stock market closed today, the most practical preparation is to treat Monday like a “headline + liquidity” session.
1) Expect thinner liquidity and sharper gaps
Reuters noted the holiday period often features lighter volume, which can amplify moves. That matters for defense and especially space names, where float dynamics and retail participation can be more pronounced. [18]
2) Watch for follow-up headlines on China–U.S. tensions
The sanctions list is already out; what moves markets next is escalation (more measures, new export controls, diplomatic statements) or a rapid cooling narrative. Reuters framed the sanctions as a response to U.S. arms sales to Taiwan and described them as largely symbolic—yet Monday trading often reacts to the headline first and nuance later. [19]
3) Track Europe defense momentum—and Ukraine diplomacy
The UK–Germany artillery deal reinforces ongoing procurement activity, while Ukraine peace-plan headlines can swing European defense sentiment quickly. Even if your portfolio is U.S.-only, European moves can shape global sector flows and comparable valuations. [20]
4) Keep an eye on the rate narrative
Reuters’ week-ahead preview said investors were focused on the path of rate cuts and noted upcoming Fed communications as a market catalyst. Rates matter for space stocks in particular because they’re often valued on longer-dated growth expectations. [21]
5) Know your trading window
If you trade around catalysts, remember that many brokers offer pre-market access, while the NYSE core session starts at 9:30 a.m. ET. [22]
Bottom line for space and defense stocks heading into Monday
Space and defense stocks are entering the next session with a supportive longer-term backdrop—budget authorization momentum and ongoing global procurement—while also facing the kind of near-term, headline-driven tape that can punish complacency.
The weekend’s biggest investable signals are clear:
- China’s sanctions list puts geopolitics front-and-center for names with defense exposure (and for Boeing, renewed attention on broader China exposure). [23]
- Europe remains in active rearmament mode, even as peace-plan talk returns to the headlines. [24]
- In space, competition for national security work is intensifying, with Blue Origin signaling it wants a bigger slice of defense and intelligence launch markets. [25]
For investors, the best “before-the-bell” posture is less about predicting a single headline outcome and more about managing exposure: understand which holdings are backlog-driven, cash-flow resilient primes versus high-beta space growth names, and be ready for Monday’s first hour to set the tone for the final trading days of 2025.
