Aerospace and defense equities have become the most oversold segment within the industrials sector, according to analysis reported on July 20, 2026. Key industry players like RTX Corp. and Lockheed Martin now trade below their 50-day moving averages. Their collective 14-day relative strength index (RSI) has dropped to 28.5, significantly below the standard oversold threshold of 30. This technical weakness comes just ahead of the sector's second-quarter earnings season, creating a setup where disappointing results could extend the selloff, while beats may trigger a sharp relief rally.
Context — why this matters now
A sector-wide oversold reading this deep is uncommon outside of major geopolitical shocks or systemic market corrections. The last comparable instance occurred in October 2025, when defense stocks saw their RSI fall to 27.8 following a broader market sell-off driven by Fed tightening fears. That episode was resolved by a 9% sector rally over the subsequent four weeks as earnings estimates held firm.
The current macro backdrop features relatively stable long-term interest rates, with the 10-year Treasury yield holding around 4.2%. This provides a neutral to favorable environment for capital-intensive industrial names. The trigger for the recent underperformance is not a single event but a confluence of profit-taking and pre-earnings positioning.
Institutional investors are trimming exposure after a strong first-quarter performance, with the iShares U.S. Aerospace & Defense ETF (ITA) gaining 14% from January to April. Recent commentary from some sell-side analysts has also flagged concerns over potential order delays in a contentious U.S. election year. This has created a negative sentiment loop, pushing valuations toward technical extremes just as fundamental catalysts arrive.
Data — what the numbers show
Quantitative analysis reveals the depth of the current selloff. The Dow Jones U.S. Select Aerospace & Defense Index has declined 7.2% from its May 2026 peak of 1,428. This contrasts with a 1.5% decline for the S&P 500 Industrial Sector Index over the same period. Major constituents show significant individual weakness. RTX Corp. trades at $112.40, down 8.5% from its 52-week high and 4.1% below its 50-day moving average of $117.18.
Lockheed Martin shares are at $465.20, a 6.3% drop from their recent high. The average price-to-earnings ratio for the top five U.S. defense primes has compressed to 18.2, down from 19.8 in April. Trading volumes for the sector ETF have been elevated, averaging 1.2 million shares daily over the past week compared to a 90-day average of 850,000. This indicates active repositioning.
| Metric | Aerospace/Defense Index | S&P 500 Industrials | Performance Delta |
|---|
| YTD Return | +4.8% | +6.1% | -1.3ppt |
| 30-Day Return | -5.1% | -2.3% | -2.8ppt |
| 14-Day RSI | 28.5 | 42.1 | -13.6pts |
These figures confirm the group's relative underperformance and its isolation as the most technically distressed segment within the broader industrial complex.
Analysis — what it means for markets / sectors / tickers
The oversold condition creates asymmetric risk for both bulls and bears. For large-cap defense primes like Lockheed Martin (LMT), Northrop Grumman (NOC), and General Dynamics (GD), earnings beats could translate to swift 3-5% single-day rallies. Their fixed-price contract backlogs provide high earnings visibility, which should support guidance. The risk is that any commentary hinting at budget uncertainty from management could validate the bearish positioning and push the sector into a deeper correction.
Second-order beneficiaries include specialized suppliers like TransDigm Group (TDG) and HEICO Corporation (HEI). Their stock prices often exhibit higher beta to the primes' sentiment. A relief rally in the primes would likely pull these names up 1.5-2x the magnitude. Conversely, weakness could spill over into adjacent industrial technology and manufacturing sectors, such as machine tool makers, though the effect would be more muted.
A key counter-argument is that the oversold reading may simply reflect a justified derating. If inflation persists, the long-duration nature of many defense contracts could pressure margins, making current valuations less attractive. Recent options flow shows increased put buying for late August, indicating some traders are hedging against or betting on further downside post-earnings. However, the bulk of institutional positioning appears neutral to cautiously long, waiting for earnings clarity before adding significant exposure.
Outlook — what to watch next
Immediate catalysts are the earnings report dates for major sector constituents. RTX Corp. reports on July 25, Lockheed Martin on July 30, and General Dynamics on August 1. Guidance on 2027 budget expectations and supply chain cost commentary will be critical for sentiment. Any upward revisions to full-year free cash flow forecasts would likely be received positively.
Technical levels to monitor include the 200-day moving average for the iShares U.S. Aerospace & Defense ETF (ITA) at $124.50, which represents a key support zone. A decisive break below this level on high volume would signal a more profound breakdown. On the upside, a sector RSI recovery above 35 would indicate the oversold pressure is abating.

Beyond earnings, the next major macro input is the July Federal Open Market Committee (FOMC) statement on July 31. A dovish tilt could benefit all rate-sensitive industrials. The sector's performance in August will also serve as a leading indicator for broader market risk appetite heading into the autumn.
Frequently Asked Questions
What does a low RSI mean for aerospace stocks?
A low relative strength index (RSI), particularly below 30, indicates a security or sector is potentially oversold. It suggests selling pressure has been intense and may be exhausted. For aerospace stocks at RSI 28.5, it implies the recent price decline has been rapid and could be due for a near-term bounce, especially if a positive catalyst like strong earnings materializes. However, an RSI can remain low during sustained downtrends, so it must be confirmed by a shift in price action and volume.
How do defense stocks typically perform during election years?
Historically, U.S. defense stocks exhibit volatility but not a consistent directional bias during election years. Uncertainty over future budget priorities can cause trading ranges to widen in the months leading to the vote. Since 2000, the median annual return for the defense sector in presidential election years is +7.2%, slightly below the +9.4% median for non-election years. Performance is more tightly linked to global conflict dynamics and existing multi-year contract backlogs than to campaign rhetoric.
