Defense ETF Comparison Pits Invesco’s Veteran PPA Against Global X’s Tech-Focused SHLD

A new comparison from The Motley Fool examines two exchange-traded funds that approach the aerospace and defense sector from different angles: the Invesco Aerospace & Defense ETF (NYSEMKT:PPA) and the Global X Defense Tech ETF (NYSEMKT:SHLD).

According to the analysis, PPA brings a long track record and broad exposure across defense-related industrial companies, while SHLD takes a lower-cost, technology-oriented approach that emphasizes software-defined systems and emerging defense technologies rather than legacy hardware alone.

Defense spending has historically remained relatively resilient across economic cycles, a characteristic that has made aerospace and defense ETFs a popular vehicle for investors seeking targeted exposure to the sector. Both funds tap into that same broad industry theme, but the comparison highlights a meaningful split in strategy: PPA’s diversified industrial footprint versus SHLD’s tilt toward newer technologies such as AI-enabled and software-driven defense capabilities.

The broader trend toward technology-centric defense spending has also lifted investor interest in adjacent funds focused on automation and artificial intelligence. Among them is the Global X Robotics & Artificial Intelligence ETF (BOTZ), which closed most recently at $34.63, down 0.09% from its prior close of $34.66. The fund commits at least 80% of its total assets to securities in an underlying index designed to capture developed-market companies involved in the development of robotics and artificial intelligence technologies — capabilities increasingly relevant to modern defense procurement.

The Motley Fool comparison also includes performance and risk metrics for both funds, noting that beta is calculated from monthly returns over up to five years of available fund history relative to the S&P 500, while dividend yield reflects trailing-12-month distributions. Readers can review the full side-by-side breakdown in the original analysis.
