Frequently Asked Questions

Question: Are defense contractors a good investment during a recession? Yes. During the 2008 recession, the defense sector gained 4.2% while the S&P 500 fell 38.5%. Long-term government contracts and essential national security spending make these stocks highly resilient.

Question: What is the best defense and space ETF? For diversification, I recommend iShares U.S. Aerospace & Defense ETF (ITA) with a 0.42% expense ratio. For equal-weight exposure, SPDR S&P Aerospace & Defense ETF (XAR) is better.

Question: Can individual investors buy SpaceX stock? Not directly on public exchanges. SpaceX is private. However, you can access it via secondary markets like Forge Global or through funds like Destinations Space ETF (MITA), which holds SpaceX shares.

Question: How much of my portfolio should be in defense stocks? I recommend 8–12% for a balanced portfolio. Conservative investors can go up to 15%, while aggressive investors might allocate 20% with a focus on space growth stocks.

Question: What is the biggest risk for defense contractors in 2025? U.S. debt ceiling negotiations could lead to a 5–10% defense budget cut. If sequestration returns, Lockheed Martin's revenue could drop by $6.8 billion, impacting its stock by 15–20%.

Question: How do space stocks differ from traditional defense stocks? Space stocks have higher growth (9–12% CAGR) but lower revenue predictability and negative free cash flow. Defense stocks offer stable dividends (2–3% yield) and lower volatility.
