Select STOXX Europe Aerospace & Defense ETF is trading down 5.1% at $39.29 in after-hours trading as investors reassess risks surrounding the escalating Iran conflict and rising energy costs.

  • The decline reverses a portion of the ETF's recent rally, which was driven by increased military spending and heightened geopolitical tensions.
  • Market pressure is attributed to profit-taking following strong gains, alongside shifting expectations for central bank policy and increased volatility in the defense sector.
