Samsung Electronics closed down 2.42% at 262,000 won on August 8, falling even as the company published record earnings results. The stock had already slipped 1.5% in earlier Thursday trading following the preliminary release.

Analysts attributed the decline to the market having fully priced in earnings improvements ahead of the announcement, alongside raised performance expectations across semiconductor stocks. Kim Seon-woo, a researcher at Meritz Securities, suggested upward revisions to next year's earnings estimates or expanded shareholder return policies could support a later rebound.
