Key signals

  • Samsung stock down 10% despite record quarterly profit
  • Earnings driven by high memory chip prices during April-June 2026
  • Investor concerns centered on scale of capital investments
  • AI demand fueling semiconductor capacity expansion
  • Market skepticism on sustainability of AI chip demand vs. capex outlays
