Micron Sees Over $100 Billion Market Cap Loss in $1.2 Trillion Chip Selloff
MU•Micron's market cap dropped by over $100 billion as the Philadelphia Semiconductor Index plunged more than 8% in its worst day since April 2025, contributing to a $1.2 trillion rout across chip stocks. Overseas, the iShares MSCI South Korea ETF sank 11%, reflecting memory supply-chain stress.
1. Sector-Wide Semiconductor Rout
Chip stocks endured their worst session since April 2025, erasing roughly $1.2 trillion in market value as the Philadelphia Semiconductor Index slid more than 8% and the iShares Semiconductor ETF tracked a similar decline.
2. Micron's Market Cap Slump
Micron saw its market value plunge by over $100 billion, ranking among the top three decliners alongside Nvidia and TSMC, as investors unwound positions in the AI and memory sectors.
3. Overseas Memory Supply-Chain Pressure
The iShares MSCI South Korea ETF dropped 11%, its worst day since March 2020, driven by steep declines in Samsung Electronics and SK Hynix, signaling stress in the global memory and AI supply chain.
4. Potential Broader Market Impact
While the S&P 500 lost nearly 2% and the Nasdaq 100 underperformed, market internals remained mixed; a failure to stabilize semiconductors next week could trigger a wider selloff across technology and industrial sectors.
