Super Micro Computer Inc. slumped 7.6% after announcing a proposed $7 billion equity raise to fund AI server orders, while Arm Holdings and ServiceNow each fell more than 6% as the chip-sector bounce from Monday stalled on renewed geopolitical risk. The iShares Semiconductor ETF (SOXX) shed 1.6% to close at $562.14, the S&P 500 eased 0.3% to 7,386.65, and the Nasdaq Composite lost 1.0% to 25,678.82 as investors weighed Trump administration signals of fresh Iran strikes against a sector still digesting Broadcom's below-consensus AI chip guidance from June 3.

Super Micro falls 7.6% on $7 billion equity raise
Super Micro Computer Inc. (NASDAQ: SMCI) was the day's sharpest decliner, closing down 7.6% at $40.64 after the AI server manufacturer announced a proposed $7 billion offering of equity and equity-linked securities to fund its expanding AI equipment order backlog. Bloomberg and BusinessWire reported the transaction on Tuesday, describing it as one of the largest equity capital raises in the server industry's history. The dilution risk was immediate: SMCI had surged 5.6% on Monday, reaching $43.99; Tuesday's selloff wiped out that gain and added to it. The company carries a Hold consensus among Wall Street analysts, with an average 12-month price target of $35.55, implying the stock is still priced above median analyst expectations even after the correction. Super Micro has a 52-week range of $19.48 to $62.36, and the announcement arrives as the AI server buildout narrative collides with the realities of dilutive capital formation.
ARM falls 6.2% despite record fiscal quarter
Arm Holdings plc (NASDAQ: ARM) gave back 6.2%, closing at $324.86, in a move that underscores the tension between strong fundamentals and stretched valuations across the AI chip stack. ARM reported Q4 fiscal 2026 revenue of $1.49 billion, up 20% year-over-year, with licensing revenue rising 29%, results that Investing.com described as record figures. Barclays set a price target of $360 on June 1, reflecting analyst confidence in AI-driven CPU demand. Yet ARM shares have gained 183% year-to-date, and Tuesday's macro headwinds, including the Iran-related risk aversion that weighed on the broader technology sector, provided sufficient cover for profit-taking. The backdrop is the sector hangover following Broadcom's June 3 earnings, where the chipmaker beat on revenue but guided next-quarter AI chip sales slightly below consensus, triggering a 10% SOXX decline on June 6, its worst session in six years, before a partial 6% rebound on Monday. ARM is still one of the sector's largest YTD winners, but that gap relative to the index has become a source of gravitational pull on down days.
ServiceNow gives up conference-season gains
ServiceNow Inc. (NYSE: NOW) dropped 6.3% to $106.97, reversing a recent run that had carried the stock up nearly 17% over the prior month. The company presented at three major technology conferences in early June, including the William Blair Growth Stock Conference, the Bank of America Global Technology Conference, and the Evercore Global TMT Conference on June 3. Its Q1 2026 results, filed with the SEC in April, showed subscription revenues of $3.67 billion, up 22% year-over-year and ahead of the high end of the company''s own guidance. Chairman and Chief Executive Bill McDermott noted at the time that "ServiceNow''s first quarter performance beat the high end of our guidance once again." The stock''s YTD position remains deep in negative territory at -27.5%, suggesting the recent rally was a reversion rather than a re-rating; Tuesday''s pullback snapped that thesis, at least for now. The session''s range of $103.08 to $112.39 indicates significant intraday volatility.
Dell pulls further from all-time high
Dell Technologies Inc. (NYSE: DELL) slid 4.7% to $381.78, extending a correction from a June 1 all-time high of $469.47. The stock is now down approximately 18.7% from that peak in eight sessions. Analysis published by TradingKey and Gurufocus on Tuesday attributed the move to continued insider selling and broad profit-taking, noting that Dell''s underlying AI server business remains strong, with a record order backlog and substantial AI equipment bookings heading into the second half of the year. Analysts broadly hold Buy ratings. Dell is, by most measures, one of the AI trade''s clearest beneficiaries in 2026, with shares up 198.7% year-to-date; the current correction reflects the standard pattern of parabolic moves meeting resistance as sentiment normalises.
