US Defense Stocks Slump After Operation Epic Fury

The iShares U.S. Aerospace & Defense ETF (ITA) declined sharply in the first month following the launch of Operation Epic Fury in late February 2026, registering a near 16% drawdown by late March before a partial rebound to roughly $223 per share on Apr. 2, 2026 (ZeroHedge, Apr. 2, 2026). That trajectory — an initial wartime bid that failed to hold — prompted UBS analyst Allyson Gordon to ask clients, "Why Is US Defense Performance Lackluster?", signaling that long-standing assumptions about conflict-driven defense outperformance may be in flux (ZeroHedge, Apr. 2, 2026). For institutional investors, the episode raises immediate questions about earnings trajectories, contract timing, and market positioning in names such as RTX, LMT, NOC and GD, as well as passive exposures through ITA. This report consolidates observed market moves, parses likely drivers cited in primary research, compares sector performance to broader equity benchmarks, and outlines risk and timing considerations for portfolio teams. Sources used include the ZeroHedge dispatch (Apr. 2, 2026), the UBS client note referenced therein, and public market data through the same reporting window.

Context

The conventional market reaction to kinetic geopolitical events has historically favored defense primes and weapons manufacturers; early shocks often generate rallying bids as investors front-run contract rephasing and procurement acceleration. In late February 2026, the initiation of Operation Epic Fury created exactly such expectations, and ITA initially caught an early bid as market participants priced in higher defense spending and expedited programs (ZeroHedge, Apr. 2, 2026). The unusual aspect in this episode is the rapid reversal: within roughly four weeks the ETF posted a nearly 16% decline from its early rally high to late-March levels, a dynamic UBS highlighted as puzzling. That performance diverged from investor memory of prior conflict episodes where defense sector outperformance persisted for months; the divergence forces a re-examination of both the macro and idiosyncratic drivers at play.

The macro backdrop in Q1–Q2 2026 is materially different from prior conflict cycles. Global interest-rate settings remain a key constraint: real yields are higher than in many previous wartime environments, elevating discount rates applied to long-duration defense backlog and defense-related free cash flows. Simultaneously, commodity and supply-chain dislocations that might have lifted some industrial margins are mixed, with certain inputs constrained while labor and capital costs have risen. UBS's internal questioning, as summarized in public reporting, reflects that investors are balancing near-term conflict news flow against these structural, rate-driven headwinds, which can compress valuation multiples even as nominal defense budgets expand.

Finally, market structure and positioning matter. Passive flows into ETFs like ITA can magnify moves when headlines trigger rebalancing, but the subsequent unwinding of leveraged tactical positions and profit-taking can produce a snapback that erodes any sustained rally. Short interest and options flow around legacy primes often spike in such episodes; while comprehensive short data post-Operation Epic Fury is proprietary, trade desks reported elevated hedging activity in the first two weeks after the operation began. For institutional allocators, the combination of headline-driven price swings, elevated rates, and structural positioning contributes to a less predictable defense beta than in historical episodes.

Data Deep Dive

ZeroHedge reported that ITA was down nearly 16% by late March 2026 after an initial rally in the first phase of Operation Epic Fury, and that the fund was trading around $223 on the morning of Apr. 2, 2026 (ZeroHedge, Apr. 2, 2026). Those are the two most concrete market data points that catalyzed UBS's client note. The magnitude—~16%—is notable because it occurred during what many investors expected to be a sustained conflict premium, indicating either earnings risk or multiple compression. The timing—late March into early April—overlaps with quarterly reporting windows for several defense primes, which may have amplified sensitivity to forward guidance and contract cadence.

Earnings calendars are critical: prime contractors routinely schedule major contract awards and classified program disclosures on a multi-quarter cadence, and any perceived delay in awards or layered inflationary pressure on margins would weigh heavily on near-term free cash flow. While public filings in Q1 2026 for large primes remain company-specific, UBS's note suggests that market participants were not seeing the contract acceleration that would justify a persistent re-rating. In addition, the defense supply chain includes a mixture of classified programs (with limited near-term revenue recognition) and commercial aerospace exposure; the latter continues to face variable demand recovery, which can dampen the defensive narrative for integrated aerospace & defense names.

From a relative performance perspective, ITA's near-term underperformance versus broader benchmarks raised eyebrows. Passive benchmark comparisons indicate that sector-level dispersion increased materially after the operation began: defense names that derive a material share of revenue from classified programs saw different flows than firms more exposed to commercial aerospace. While comprehensive index-level performance versus the S&P 500 (SPX) and Nasdaq (NDX) across the exact window is dataset-dependent, UBS's client note and market color underline that defense equities did not behave as a homogeneous "safe haven" or risk-on sector in this instance.

Sector Implications

For defense primes, the market is now bifurcating valuation drivers: contract cadence and classified program visibility versus inflation-adjusted margins and balance-sheet leverage. Firms with shorter contractor cycles and backlog that can be recognized within quarters will naturally be better positioned to translate geopolitical developments into stock performance. Conversely, names with long-duration backlog but higher exposure to commercial aerospace supply chains may find their defensiveness questioned by investors. This split matters for portfolio construction: an allocation to the sector via ITA embeds all these exposures, while active stock selection can isolate faster-realizing defense revenue streams.

Procurement timelines are not instantaneous. Even with renewed political support for increased defense budgets, the pipeline from congressional authorization to award execution and revenue recognition can take months to quarters. Institutional investors should note that a headline on Feb. 28, 2026 (late February launch) is not equivalent to immediate billings for many suppliers; consequently, the market's early enthusiasm can be mis-timed relative to cash-flow realities. UBS's probing question in its note implicitly underscores that markets are attempting to price a future whose revenue realization lags the geopolitical event.

A further implication is that multiple compression remains a live risk. If nominal defense spending expectations increase but interest rates remain elevated, discount-rate effects can offset some of the valuation upside from higher nominal profits. In addition, inflation in key inputs—semiconductors, specialty metals, and advanced electronics—can compress margins even as topline grows. These sector-level frictions help explain why a tactical wartime rally might not persist in the face of macroeconomic and cost-structure realities.

Risk Assessment

Headline risk remains elevated and will likely produce volatility spikes tied to operational updates, congressional votes on supplemental budgets, and quarterly company disclosures. For instance, any delay in congressional appropriation of supplemental funding or material changes to the composition of such packages could materially alter revenue trajectories for primes over 12–18 months. The market is sensitive not only to the quantum of funding but to how it is allocated across platforms and whether procurement shifts to accelerate near-term spending versus long-term R&D.

Counterparty and supply-chain risk is another material factor. If sanctions, logistics disruptions, or supplier bankruptcies constrain the ability to scale production of electromechanical components, primes could face bottlenecks that compress margins. Given the mixed commercial recovery in global air travel, firms with larger commercial aerospace exposure also carry demand risk that can offset defense tailwinds. UBS's note captures this constellation of risks implicitly by highlighting the dissonance between headline-driven expectations and market outcomes.

Market liquidity risk can exacerbate moves: ETFs such as ITA concentrate positions in the largest primes, and forced rebalancing or deleveraging during spikes in volatility can amplify price moves beyond what company fundamentals alone would justify. Institutional traders should therefore consider liquidity-adjusted position sizing and stress tests that account for headline-driven flow reversals, not merely fundamental earnings scenarios.

Outlook

Over the next 3–12 months, the path for defense equities will hinge on three discrete inputs: statutory appropriations and the timing of awards, margin behavior as input costs evolve, and the wider interest-rate trajectory that determines valuation multiples. If Congress fast-tracks supplemental funding and awards begin to flow with clear near-term recognition, the sector could re-rate positively; absent that, multiple headwinds could keep prices depressed despite improving nominal defense budgets. UBS's questioning of durable performance is therefore a reasonable prompt for investors to demand clearer revenue visibility before repricing the sector higher.

That said, volatility itself creates opportunity for active managers and long-term investors who can differentiate contract timing and supply-chain resilience across names. Passive allocations via ITA will capture headline-driven swings and cannot isolate idiosyncratic winners. Firms that can demonstrate near-term revenue recognition from conflict-driven procurement and manage input inflation effectively stand to perform better versus their peers. Monitoring contract award announcements, backlog digestion rates, and quarterly guidance will be essential to separate signal from headline noise.

Institutional risk frameworks should incorporate scenario-based stress tests that model different funding and rate environments. A base case should assume a lag of several quarters between political commitment and revenue recognition; an upside case would assume expedited awards and modest input-cost inflation; a downside would include rate-driven multiple contraction and supply-chain stoppages. These scenarios will materially alter expected returns for both active stock picks and ETF allocations.

Fazen Capital Perspective

Fazen Capital view: the market's quick reversal in defense equities reflects an information gap between headline-driven expectations and the contractual realities of defense procurement. Contrary to the intuitive narrative that "war equals short-term alpha for defense stocks," we believe the decisive variable over the next 6–12 months will be the cadence of contract awards and their revenue recognition mechanics. That means a tactical, event-driven trade into broad ETFs like ITA is more exposed to liquidity and positioning risk than is often appreciated; active selection with a focus on award pipelines and classified-program disclosure timing offers a cleaner exposure.

A contrarian insight: higher headline-related volatility may paradoxically compress consensus forward multiples, creating idiosyncratic entry points for select primes that have robust order books and manageable commercial aerospace exposure. Where the market has extrapolated a lack of immediate revenue realization into permanent de-rating, disciplined fundamental investors could find attractive risk-reward windows. This is not a universal view — it requires company-level verification of backlog convertibility and supply-chain resilience.

We also flag a structural change: investors are increasingly pricing defense equities through a macro-finance lens (rates, inflation) rather than a pure geopolitical-bid lens. That shift means alpha is more likely to be found in corporate execution and balance-sheet management than in top-line growth alone. Institutional teams should therefore reweight analytical effort toward cash-flow timing models and procurement-law timelines rather than short-term headline correlation studies.

Bottom Line

The near 16% drawdown in ITA by late March 2026, followed by a rebound to about $223 on Apr. 2, 2026, underscores that geopolitical headlines do not mechanically translate into sustained defense-sector rallies; contract timing, margins, and rates matter. Investors should prioritize award cadence, margin sensitivity, and liquidity-managed implementation when assessing exposure to defense equities.

FAQ

Q: Will a new U.S. supplemental defense appropriation automatically lift defense stocks? A: Not automatically. Markets price realized revenue and near-term cash flows. Congressional appropriation is a necessary but not sufficient condition — the timing of awards, obligations, and revenue recognition determine when and whether equities re-rate.

Q: Historically, have defense stocks always outperformed during conflicts? A: No. Performance has varied by conflict and macro backdrop. Where conflicts coincided with low rates and clear procurement acceleration, defense equities tended to outperform. In higher-rate environments with supply-chain friction, the relationship weakens.
