Super Micro surges 16% while Alphabet and Palantir fall as chip equipment parts ways with hyperscalers, SOXX +2.4%

Super Micro Computer Inc. (NASDAQ: SMCI) soared 15.7% Monday after fiscal third-quarter server revenue of $10.24 billion, up 122.7% year over year, cleared analyst estimates alongside non-GAAP earnings of $0.84 a share. The Nasdaq Composite slipped 1.3% to 26,167 as Alphabet, Amazon, and Palantir each fell roughly 5-7% on regulatory and valuation pressure, but the Philadelphia Semiconductor Index gained 2.4% to $655.01, a stark divergence underscoring continued demand for AI data-center hardware even as sentiment soured on the software and hyperscaler layer. The S&P 500 edged down 0.4% to 7,472.

Today's biggest movers

Super Micro surges 15.7% on AI server revenue beat

Super Micro Computer Inc. (NASDAQ: SMCI) closed at $35.46 after touching an intraday high of $36.80 on volume exceeding 124 million shares, roughly three times its recent daily average. The catalyst was fiscal Q3 2026 earnings: revenue of $10.24 billion grew 122.7% year over year, and non-GAAP earnings per share of $0.84 exceeded consensus estimates. The quarter confirms SMCI as a primary beneficiary of the AI server build-out, with direct-liquid-cooled rack systems winning design-ins at major US and Asia-Pacific cloud operators. Gross margin compression remains a watch item, with the figure declining to 3.2% in Q2 from 5.6% a year earlier as component costs and competitive pricing pressure bite. The Wall Street consensus per 13 analysts is Hold, with an average price target of $38.23, meaning Monday's close is now approaching the Street's median fair-value estimate. Supply-chain constraints in rack assembly and data-center deployment readiness among some cloud customers are the two risks cited most frequently.

Arm Holdings drops 7.2% as valuation call catches up with the rally

Arm Holdings plc (NASDAQ: ARM) was the session's sharpest faller in the chip complex, declining 7.2% to $407.72. New Street Research initiated the retreat on June 18 by cutting the stock from Buy to Neutral, arguing the year-to-date rally of more than 255% had stretched the trailing price-to-earnings ratio above 490 times, leaving essentially no margin of safety even if licensing and royalty trends remain intact. Full-year fiscal 2026 results showed revenue of $4.92 billion, up 23% year over year, with adjusted EPS of $0.85 - solid numbers the market had largely already priced in, per New Street. Monday also marks the effective date of the Nasdaq-100 semi-annual rebalance, which swapped in five new constituents and removed five, a mechanical shift that can amplify pressure on names where index weights are trimmed. Bernstein holds a contrarian view, raising its target to $500 and pointing to accelerating data-center royalties as ARM-based designs displace x86 in server workloads. The stock remains up 255% year to date. For context on ARM's prior run, see the June 17 recap.

Palantir falls 7% as UK Parliament presses on NHS contract

Palantir Technologies Inc. (NYSE: PLTR) fell 7% to $119.50, its largest single-session decline in several weeks, as political pressure on the company's UK government contracts intensified. Members of Parliament renewed calls last week to exercise a February 2027 break clause in Palantir's £330 million Federated Data Platform contract with the National Health Service, following the earlier blocking of a separate £50 million Metropolitan Police agreement. Health ministers have begun publicly preparing NHS contingency plans. The regulatory overhang sits on top of a valuation many buy-side managers struggle to justify: PLTR trades at more than 113 times forward earnings and 42 times forward revenue. Business momentum remains strong - first-quarter 2026 revenue reached $1.63 billion, up 85% year over year, with full-year 2026 guidance raised to approximately $7.65 billion. The average analyst price target of $185.93 implies more than 55% upside from Monday's close, but the stock is down 28.8% year to date. The NHS contract remains the clearest near-term binary risk.

Lam Research and Intel extend the chip equipment re-rating

Lam Research Corp. (NASDAQ: LRCX) added 5.3% to $409.54, capping a one-month run of 35.5% driven by a wave of analyst target increases. Wells Fargo set a $450 target, Cantor Fitzgerald analyst C.J. Muse set $425 at Overweight, Oppenheimer is at $400 with Outperform, and UBS holds Buy at $375. All four cite a multi-year upcycle in etch and deposition equipment driven by AI memory, advanced packaging, and gate-all-around node transitions. Applied Materials Inc. (NASDAQ: AMAT) rose 3.7% to $640.18 on the same demand picture, extending its one-month gain to 49.8%.

Intel Corp. (NASDAQ: INTC) rose 5.2% to $140.94, continuing the foundry re-rating that has pushed shares up 257.9% since January. Monday's session was buoyed by reports that Nvidia and Google are evaluating Intel's 18A-P process node as a backup fabrication source for AI accelerators, extending the Apple-linked foundry narrative from the June 18 recap. Intel confirmed 18A-P entered risk production on schedule, with power and performance results supporting its bid to reclaim leading-edge manufacturing status. Bank of America issued a rare double upgrade to Buy, setting a $135 price target with a path to $6-plus earnings per share by 2030. Intel reports second-quarter results July 23.

Notable but quieter

Oracle Corp. (NYSE: ORCL) fell another 5% to $175.07, extending the correction that began June 11 when the stock dropped more than 11% despite record fiscal Q4 2026 revenue of $19.18 billion, up 21%, and Oracle Cloud Infrastructure growth of 93%. "It is not the print, it is the spending that continues to concern investors," Futurum Group analyst Daniel Newman said at the time, referring to Oracle's rising capital expenditure commitments. The average analyst target of $252.64 implies more than 40% upside, but near-term sentiment remains negative.

Alphabet Inc. (NASDAQ: GOOGL) declined 5% to $349.68 after a California judge denied YouTube and Google a new trial in a case where a jury found their platforms were designed in ways addictive to minors. The ruling keeps Alphabet exposed to damages and potential copycat litigation. The Department of Justice's ongoing appeal seeking Chrome divestiture also continues to weigh on the stock, with the D.C. Circuit expected to hear arguments in late 2026 or early 2027. Despite Monday's drop, 28 of 33 analysts rate GOOGL a Buy, with an average target raised to $493.30.

Broadcom Inc. (NASDAQ: AVGO) fell 4.7% to $392.13 with no company-specific catalyst, pulled down by the broad hyperscaler rotation; the stock remains up 12.8% year to date. Amazon.com Inc. (NASDAQ: AMZN) lost 4.8% to $232.79 ahead of second-quarter earnings expected July 30, with consensus calling for Q2 EPS of $1.81. Advanced Micro Devices Inc. (NASDAQ: AMD) bucked the session's weakness, adding 2.7% to $551.63 to extend its one-month gain to 22.7% and year-to-date gain to 146.9%.

What to watch tomorrow

NVIDIA Corp. (NASDAQ: NVDA) hosts its Annual Stockholder Meeting Wednesday, June 24, where management is expected to address Blackwell GPU production ramp timelines and the Vera Rubin architecture roadmap. Intel reports second-quarter earnings July 23; any commentary on 18A-P yield rates will be market-moving. Amazon reports Q2 results July 30, with the market looking for evidence that AWS AI-infrastructure revenue is accelerating following Monday's 4.8% pullback. UK parliamentary hearings on Palantir's NHS contract are expected to continue this week, representing the clearest near-term binary catalyst for PLTR. Macro watchers will focus on the PCE price deflator due later this week; a softer reading could provide relief for rate-sensitive parts of the AI complex. For context on how rate expectations have shaped AI sector moves this month, see the June 15 recap.
