State Street SPDR S&P Aerospace & Defense ETF (XAR) seeks to track the S&P Aerospace & Defense Select Industry Index, which measures the performance of U.S. companies primarily engaged in manufacturing aircraft, spacecraft, missiles, defense equipment, and providing related services to government and commercial customers.
How It Works
XAR uses a passively managed, market-capitalization-weighted approach that holds all constituent stocks in proportion to their market value within the aerospace and defense sector. The fund rebalances quarterly to maintain alignment with index changes and sector developments. Holdings typically include major defense contractors, commercial aircraft manufacturers, satellite companies, and aerospace component suppliers, creating concentrated exposure to approximately 30-40 specialized industrial companies.
Key Features
- Pure-play exposure to aerospace and defense sector, avoiding dilution from broader industrial ETFs that mix in unrelated companies
- Captures both government defense spending cycles and commercial aviation recovery trends in single targeted investment vehicle
- Established 13-year track record with 0.35% expense ratio, providing cost-effective access to specialized industrial niche
Risks
- This ETF can lose value when government defense budgets face cuts or commercial aviation demand weakens, potentially declining 20-30% during sector downturns
- High sector concentration means company-specific issues at major contractors like Boeing or Lockheed Martin significantly impact overall fund performance
- Cyclical nature of aerospace industry creates volatility during economic recessions when both military and commercial spending typically contracts simultaneously
Who Should Own This
Best suited as a satellite holding (5-10% of portfolio) for investors with 3+ year time horizons seeking targeted exposure to defense spending and aviation recovery themes. High risk tolerance required due to sector concentration and cyclical volatility. Appeals to tactical investors positioning for geopolitical tensions or commercial aviation rebounds.
