NASAETF

The article compares two aerospace ETFs: iShares U.S. Aerospace & Defense ETF (ITA) and Tema Space Innovators ETF (NASA). ITA offers broader exposure to established defense companies at a lower cost (0.37% expense ratio) with less volatility, while NASA provides focused, higher-risk exposure to commercial space companies with a 0.75% expense ratio. ITA is recommended for most investors seeking lower costs and stability, while NASA appeals to those specifically targeting space innovation despite greater volatility.

Space sector ETFs present an attractive entry point following recent valuation pullbacks, despite third-quarter corrections caused by rising Treasury yields and macroeconomic pressures. The global space economy reached $686 billion in 2025 with strong fundamentals, and is projected to surpass $1 trillion by 2032. Space ETFs offer diversified exposure across the industry's value chain, mitigating risks from individual company setbacks.
