Chip rout deepens as China supply fears rattle Micron and peers

Micron Technology’s MU slid 8.9% on Tuesday and is down more than 29% in July, putting it on track for its worst monthly drop since 2015, as investors fret about China’s domestic chip and tooling supply and possible export controls. Other memory and storage names like Sandisk (SNDK) and Western Digital (WDC) also declined, amid a broader chip-supply scare tied to China’s push for homegrown lithography and memory tech (CXMT, ChangXin Memory Technologies) and policy moves such as the MATCH Act. Analysts cite geopolitical and supply-chain dynamics, with Nvidia’s AI commitments and ASML’s dominant position shaping sentiment, signaling a cautious, risk-off tone for tech hardware and AI-related equities.
