description: "⏰ What’s Happened To Korea’s Market?South Korea saw a historic sell‑off today( 28 July 2026). The KOSPI plunged -10.84% , its worst single day since March 2026. Leading the crash: SK Hynix down 14.7% and Samsung Electronics down 14.4%, both posting record one‑day falls.This sharp drop is driven by three big worries: Doubts over whether heavy AI spending can keep up, geopolitical tensions and fast‑rising competition from China.The fall also remind or signals  a much more cautious outlook for the whole global memory sector. Before rushing to “buy the dip,” remember: weakness in these giants may be a warning for memory stocks everywhere.Key watchpoint: Both companies report earnings this week, their updates will decide if sentiment stabilises or worsens. Trade carefully and do your homework first.$SK Hynix(SKHY.US)"
