SPTE is trading 2.6% up in after-hours trading, appearing to reflect stabilization after the September 14–15 AI-stock selloff.

  • The rebound does not appear tied to a new positive sector-wide catalyst.
  • Warnings from Anthropic, OpenAI, and xAI pressured chipmakers and AI infrastructure stocks; NVIDIA fell 3.4% on September 15.
  • The September 16, 2026 outlook remains cautious: Treasury yields above 5%, higher oil prices, and expectations for a Federal Reserve rate hike continue to pressure growth stocks.
