Asian technology stocks tumbled Friday, tracking a sharp sell-off on Wall Street overnight that sent the tech-heavy Nasdaq Composite into correction territory. The artificial intelligence (AI) boom has turned companies like Samsung Electronics and SK Hynix into some of the world's biggest stock market winners over the past year. SK Hynix shares fell 4.23% to their lowest level since April, extending a seven-session slide that has erased 31% of their value.
