A Tiny Defense ETF Just Smashed The S&P 500 By Nearly 30% | PPA VOO

The Invesco Aerospace & Defense ETF (NYSEARCA:PPA | PPA Price Prediction) has crushed the broader market over the past year, delivering 44% returns compared to the S&P 500’s 16% gain. This outperformance stems from concentrated exposure to defense contractors that benefit when military budgets expand and geopolitical tensions rise. The trend has accelerated recently as defense spending proposals gain momentum in Washington.

President Trump’s proposal for a $1.5 trillion defense budget in 2027 would represent a massive 66% increase from current spending levels. This policy shift has ignited a rally across the fund’s major holdings, with defense contractors pricing in larger contract awards and improved revenue visibility. The fund’s concentrated portfolio structure means these gains flow directly through to overall performance. Other major holdings include Lockheed Martin (NYSE:LMT), Northrop Grumman (NYSE:NOC), and RTX (NYSE:RTX), which have also posted strong gains.

The Defense Budget Tailwind Isn’t Going Away

Defense spending trends matter more than anything else for this fund. When governments allocate more money to military budgets, contractors get larger orders and higher revenue visibility. The macro driver to watch is legislative action on U.S. defense appropriations, particularly the fiscal 2027 budget cycle currently taking shape in Congress.

Track the annual National Defense Authorization Act process, which typically moves through committee markups in spring and floor votes by summer. The White House Office of Management and Budget releases detailed budget requests in February or March, showing exactly which programs are getting funded and by how much. European defense spending is also accelerating, with NATO members increasing budgets in response to ongoing tensions with Russia.

Rising geopolitical instability translates directly into weapons orders, maintenance contracts, and modernization programs. The more unpredictable the global environment becomes, the more countries spend on defense capabilities, creating a sustained revenue pipeline for the contractors PPA holds.

Concentration Risk Is the Real Story

Concentration defines this fund’s risk-reward profile, with the top 10 holdings commanding 59% of assets. This structure amplifies gains during defense rallies but creates vulnerability to individual company setbacks. The fund charges a 0.58% expense ratio and offers minimal yield, positioning it as a pure growth vehicle for investors betting on expanding military budgets rather than income generation.

Investors should monitor the fund’s quarterly holdings updates on Invesco’s website to track any shifts in sector allocation or concentration levels. The biggest factor ahead is whether Congress actually approves a significantly larger defense budget, and how the fund’s mega-cap holdings execute on production targets and margin expansion as order books fill.
