MU, SNDK, DRAM Fall Sharply From Record Highs: Korean Market Crashes 10% Crash On SK Hynix, Samsung Pullback

U.S. memory chip stocks tumbled from record highs Tuesday as a broader technology selloff rippled across global markets. Micron fell 8.4%, SanDisk dropped 9.3%, and the Roundhill Memory ETF declined 13%. South Korea's Kospi index closed 10% lower, with SK Hynix and Samsung Electronics each sliding over 12% on profit-taking after a sharp recent rally.

The selloff, which began Monday in U.S. markets and spread overnight to Asia, prompted a 20-minute trading halt on the Kospi to prevent a runaway decline. Micron, SK Hynix, and Samsung—the three largest holdings in the DRAM ETF—led the losses as investors reassessed how much AI-driven growth was already reflected in share prices.
