Key Points
Invesco Aerospace & Defense ETF (NYSEMKT:PPA) offers a long track record and broad industrial exposure, while Global X Defense Tech ETF (NYSEMKT:SHLD) provides a lower-cost, technology-focused approach to the defense sector.
Defense spending often stays resilient throughout various economic cycles, making aerospace and defense exchange-traded funds a popular choice for investors seeking sector-specific growth. While both funds target the same broad industry, they differ in their approach to legacy hardware versus emerging technologies and software-defined systems. This comparison looks at how the veteran PPA stacks up against the newer SHLD.

Which looks like the better buy?
There is not a ton of daylight between these two ETFs. Indeed, they share five companies among their top 10 holdings. Assets under management are pretty close, expense ratios are just a few basis points off, and they both have relatively narrow portfolios. The difference in one-year returns is not significant (to me, anyway).
SHLD has a higher dividend yield, but has also experienced a greater maximum drawdown, which may make it less attractive to more conservative investors.
I think investors looking for diversified exposure to the defense industry would probably be well served by either SHLD or PPA. Many of the companies in their portfolios rely on the U.S. government for a significant portion of their revenue, and the cynic (realist?) in me thinks that’s probably an advantage. I cannot picture a universe where defense spending by the U.S. government decreases over time. In fact, since 1960, the defense budget has increased nearly every year, and in 2026, it is poised to cross the $1 trillion mark. If defense exposure is what you want, either ETF will work.
