Amkor Technology is trading 4.5% down now at $58.54 after rising 3.92% to $61.30 on August 17; no reliable August 18 company-specific announcement explaining the pre-market decline was found.

  • The previously reported $1.5 billion NVIDIA agreement, announced July 23, supports longer-term U.S. packaging demand but does not explain today’s drop.
  • Recent reporting mentions a possible China-unit stake sale, though no direct connection to the decline is established.
