Applied Materials Inc. (NASDAQ: AMAT) fell 5.6 pct on Friday after Moonshot AI, a Chinese artificial-intelligence startup, published a foundation model it claims rivals leading US systems, renewing investor concern that hyperscalers may curb AI infrastructure spending. The S&P 500 closed down 1.0 pct at 7,458, the Nasdaq Composite declined 1.4 pct to 25,520, and the VanEck Semiconductor ETF (SOXX) dropped 1.6 pct to $521.81 - its fifth consecutive weekly loss and roughly 18 pct below its June peak.

Applied Materials sinks 5.6 pct as Chinese AI model renews capex fears
Applied Materials Inc. (NASDAQ: AMAT) shed $31.17 to close at $529.66, its steepest single-session decline in months, as Moonshot AI, a Chinese startup, published a foundation model claiming parity with leading US systems. The news rekindled the investor calculus that struck markets in January with the DeepSeek shock: if capable models can be built at lower cost, hyperscalers may reduce the data-center build-out that drives demand for advanced chip-making equipment. Lam Research Corp. (NASDAQ: LRCX) fell 2.4 pct to $313.30 in sympathy, and ASML Holding N.V. (NASDAQ: ASML) slid 2.1 pct to $1,747.58, dragging SOXX to a weekly loss of 5.7 pct.
The selloff came despite a wall of recent analyst upgrades. UBS lifted its Applied Materials price target to $705 from $570, TD Cowen raised it to $700, and Stifel set it at $650 - all three keeping Buy-equivalent ratings and arguing that the multi-year AI capacity build-out remains structurally intact regardless of near-term model-efficiency headlines. The stock is still up 97 pct year-to-date, a gain that amplifies drawdowns when sentiment turns. Friday extends a rout that began Thursday when SOXX shed 4.5 pct on a broad chip-sector rotation.
Baidu drops 5 pct despite Apple China AI clearance
Baidu Inc. (NASDAQ: BIDU) fell 4.95 pct to $107.24, an outcome that puzzled observers given concurrent positive news. The Chinese search and AI company confirmed July 17 as the record date for an extraordinary shareholder meeting tied to its planned dual-primary Hong Kong listing, a structural move designed to deepen mainland investor access. Simultaneously, Apple received Chinese regulatory clearance to launch its AI services in China with Baidu and Alibaba as partners - a validation of Baidu's AI capabilities in the world's largest smartphone market. That both developments failed to lift the stock underscores Friday's depth of risk-off sentiment. The China-AI overhang remains acute: with the Moonshot model headline circulating, any positive US-China AI supply narrative competes against fears that Chinese AI efficiency ultimately undercuts US semiconductor revenue.
Arm Holdings gains 2 pct, but analyst divergence signals fragile recovery
Arm Holdings plc (NASDAQ: ARM) added 1.98 pct to $267.19 in a partial bounce after losing more than 36 pct over the prior month. The recovery came despite HSBC analyst Frank Lee downgrading the chip-design licensor to Hold, citing foundry capacity bottlenecks he expects to constrain near-term royalty growth, while raising his price target to $315. Running counter to that call, KeyBanc Capital Markets lifted its target to $430 from $300 and maintained an Overweight rating, pointing to Arm's expanding footprint in data-center and AI-inference silicon. The session range - from $243.12 to $272.88, a spread exceeding 11 pct of the closing price - reflects how unsettled positioning is ahead of fiscal Q1 2027 results due July 29. A 40-analyst consensus Buy with a $303.97 average target, well below where KeyBanc and others have moved, suggests the street is still re-rating the stock after its first-half surge of more than 224 pct.
