what happened
According to Stocktwits, AI-linked shares sold off sharply last week. Lumentum (LITE), CoreWeave (CRWV) and Nebius Group (NBIS) each lost more than a quarter of their value. The iShares Semiconductor ETF (SOXX) dropped 11.8%, its weakest weekly performance since March.
The selloff followed falling CoreWeave bonds, a hotter-than-expected inflation reading and renewed doubts about the durability of AI spending. Chipmakers took the heaviest hit. Relative strength index readings for CoreWeave and Applied Materials (AMAT) fell below 30, a level typically seen as oversold. Stocks edged higher in premarket trading on Monday, led by chip names.
why it matters
The drop comes ahead of third-quarter earnings from major tech companies. Reports from Netflix, Meta, IBM and Western Digital this week may set the tone for the sector and shape how investors value the AI theme.
