3119.HK is trading 3.4% down as Asian semiconductor shares weakened broadly on August 24, 2026.

  • Samsung Electronics fell more than 8% after investors judged its record shareholder-return plan disappointing, while Hong Kong-listed SMIC also declined sharply.
  • Risk reduction ahead of Nvidia’s August 26 earnings and concerns about richly valued technology and AI stocks amplified the selloff.
  • Sector-wide weakness is the clearest explanation for the ETF’s decline.
