PPA vs SHLD: Weighing Broad U.S. Defense Exposure Against a Global Tech Tilt
Key Takeaways
- PPA is a broad, U.S.-centric aerospace and defense index fund, while SHLD is a global, defense-technology thematic fund with heavier exposure to software and AI-driven companies.
- PPA is heavily concentrated in established U.S. prime contractors; SHLD adds meaningful international names and technology names such as Palantir.
- Costs are similar: PPA carries a 0.58% expense ratio versus SHLD at 0.50%.
- PPA has a two-decade track record, whereas SHLD launched in 2023 and carries a shorter performance history.
- Risk and volatility profiles differ, with SHLD historically exhibiting higher volatility due to its tech tilt and global footprint.
- Both are non-diversified funds, meaning their concentrated holdings can amplify single-stock risk.
The Evolving Landscape of Defense Investing
Defense investing has evolved rapidly as geopolitics, artificial intelligence, and software-defined warfare reshape the sector. The Invesco Aerospace & Defense ETF (PPA) and the Global X Defense Tech ETF (SHLD) sit at the center of this shift. Although both provide exposure to aerospace and defense, they do not compete on identical terms: PPA is a broad, market-cap-weighted index fund dominated by legacy U.S. prime contractors, while SHLD is a thematic fund built around the adoption of defense technology, spanning cybersecurity, big data, and advanced hardware across multiple countries. Comparing their structure, sector allocation, and cost profiles helps investors understand which vehicle better matches a given investment objective. I also checked this using Tickeron’s AI Screener to see how the two line up against peers.
A Closer Look at PPA
PPA is a passively managed exchange-traded fund that seeks to track the SPADE Defense Index, a market-capitalization-weighted benchmark of U.S.-listed companies engaged in defense, military, homeland security, and space operations. Launched in 2005, the fund holds roughly 60 to 70 securities and is classified as non-diversified, meaning a small number of large positions can drive performance.
Its portfolio is anchored in major prime contractors. Top holdings typically include RTX, BA, LMT, GE, GD, and NOC, with the top ten positions often representing more than half of fund assets. From a sector standpoint, industrials dominate at roughly 90% of the portfolio, with a smaller information technology sleeve of roughly 7% to 10%. Geographically, the fund is overwhelmingly U.S.-focused, with more than 90% of assets in domestic companies. The net expense ratio is 0.58%. A quick scan with Tickeron’s AI tools confirmed the heavy U.S. prime-contractor weighting.
Understanding SHLD’s Approach
SHLD is a thematic ETF that seeks to track the Global X Defense Tech Index, which targets companies positioned to benefit from the increased adoption of defense technology. This includes firms building cybersecurity systems, leveraging artificial intelligence and big data, and producing advanced military hardware such as robotics, fuel systems, and aircraft. Launched in September 2023, the fund holds roughly 50 to 60 securities and is also non-diversified.
The portfolio blends traditional defense contractors with technology companies. Top holdings typically include PLTR, RTX, LMT, GD, and NOC. Unlike PPA, SHLD is globally diversified, with U.S. exposure around 60% to 65% and notable allocations to companies in the United Kingdom, Germany, South Korea, France, Italy, Sweden, and Israel. Sector allocation is roughly 85% industrials and 15% technology, reflecting a meaningfully larger technology tilt than PPA. The expense ratio is 0.50%.
The Broader Defense Sector Dynamics
Both funds operate within a defense sector that has benefited from elevated global defense budgets, rising geopolitical tensions, and renewed emphasis on modernization. Governments in North America and Europe have increased procurement and replenishment spending, supporting multi-year revenue visibility for prime contractors. At the same time, a structural shift toward software-defined systems, autonomous platforms, and data analytics is redirecting capital toward technology-enabled defense names.
This backdrop creates two distinct investment currents. PPA is closely tied to traditional defense programs, aircraft production, and government space operations, making it sensitive to budget cycles and supply-chain execution. SHLD adds exposure to the faster-growing defense-technology segment, which is influenced by AI adoption, cybersecurity demand, and venture-backed innovation. Sector risks include valuation sensitivity, regulatory and export-control developments, and the potential for budget reprioritization.
How Performance and Positioning Stack Up
In recent weeks and months, the two funds have diverged in character even when their returns have moved in the same general direction. PPA has historically tracked broad aerospace and defense momentum, driven by the earnings cycles of large prime contractors and order backlogs. SHLD, by contrast, has shown greater sensitivity to technology-sector rotation, with names such as Palantir contributing outsized influence to its performance.
Relative positioning reflects these differences. PPA offers a more established, lower-volatility profile with deep liquidity and a long track record, while SHLD introduces higher volatility and greater geographic breadth. SHLD's larger technology allocation means its performance can be amplified by shifts in growth-stock sentiment and interest-rate expectations, whereas PPA is more closely anchored to industrial earnings and government spending. For investors, the choice often comes down to whether they prefer broad, U.S.-heavy prime-contractor exposure or a global, technology-leaning thematic approach. From what I see, the volatility gap stands out as the key differentiator.
Using AI Tools to Refine the Comparison
In my own research, I often turn to Tickeron’s AI Screener when evaluating thematic ETFs like these. It lets me quickly filter by industry, technical patterns, volatility, and performance metrics to spot how funds stack up against broader market trends. This kind of targeted scan helps confirm whether a thematic tilt like SHLD’s aligns with current momentum or if a more established vehicle like PPA offers better stability for a core position. The tool has become a regular part of how I cross-check sector exposure and risk characteristics before making allocation decisions.
