AMKR is trading 4% down at $82.16 in pre-market as investors take profits following a sharp multi-day rally driven by AI chip-packaging optimism.

  • The decline follows a 3.3% gain on June 25, 2026, which was fueled by sector rotation into semiconductor and AI-packaging names.
  • The pullback comes amid broader market weakness, with index futures and tech-related stocks trading lower as investors shift toward risk-off positioning.
