Wall Street holds steadier as AI stocks recover some of their sell-off
Wall Street steadied on Monday after last week’s sell-off, with the S&P 500 up 0.3% (after a 2.6% Friday drop), the Dow down 0.2%, and the Nasdaq up 0.9%. Chip and memory stocks rebounded: Micron rose 10.5% after a 13.3% Friday fall, and Marvell gained 14.7% after being set to join the S&P 500. Oil rose on Israel-Iran fighting but eased to $94.14 Brent; 10-year Treasury yields held near 4.55%.

MU’s sharp rebound is framed as AI-chip sentiment normalization after an outsized prior sell-off.
Micron Technology rose 10.5% after sliding 13.3% Friday, resuming a run where the stock has more than tripled in 2026.
Near-term volatility likely remains elevated; momentum could persist if AI/semis sentiment stabilizes.
Background
The piece is a Wall Street market wrap highlighting AI-stock sell-off and partial rebound, plus oil/yield/geopolitics context.
Why it matters
Semis/memory names are moving on a mix of sentiment normalization, index-inclusion flows (MRVL), and a new data-center optical supply deal (GLW). Broader macro (oil, yields) remains a counterweight to tech risk appetite.
Market relevance
Traders get near-term catalysts for MU/MRVL/GLW/CPB within an AI-semis rebound narrative, while oil/geopolitics and yields provide the macro risk backdrop.
Market effects
AI semis/memory are shown as sentiment-sensitive; index inclusion (MRVL) and deal-driven optics (GLW) reinforce the AI supply-chain bid.
KOSPI tech weakness (Samsung, SK Hynix) is cited as part of the sell-off, implying global semis correlation.
Israel-Iran conflict lifts oil and yields risk, which can pressure high-multiple tech/semis even as AI-specific flows rebound.
Alternative perspectives
The article frames the sell-off as potentially “healthy,” implying the rebound may be a short-lived mean-reversion rather than a durable trend.
Oil-driven inflation/yield pressure (10-year held ~4.55%) could cap upside for AI multiples if geopolitical risk re-escalates.
