SK Hynix is trading 4% down at $1320, apparently reflecting trading volatility and profit-taking after the September 21 AI-led rally.

  • No new company-specific announcement directly explains the September 22 decline.
  • The recent Global Forum emphasized AI-memory demand and expansion plans; Solidigm’s potential U.S. NAND factory remains exploratory, with no decision finalized.
  • South Korean coverage reported SK Hynix reversing earlier gains on September 22; external prices are disregarded here in favor of the supplied quote.
