AMD stock today: After-hours dip tracks year-end chip rotation after Fed minutes

AMD stock today: After-hours dip tracks year-end chip rotation after Fed minutes

NEW YORK, December 30, 2025, 16:28 ET — After-hours Advanced Micro Devices shares nudged lower in after-hours trading on Tuesday, keeping the chipmaker close to its regular-session range as investors digested fresh Federal Reserve signals and year-end positioning. The timing matters because liquidity is thin in the final days of the year, which can magnify moves in high-volatility technology stocks. Semiconductors often swing with shifts in rate expectations, since much of their value depends on future earnings. U.S. stocks closed little changed, with the S&P 500 down 0.14% and the Nasdaq off 0.23%, as gains in communication services were offset

Microsoft stock ticks up as Nadella reshuffles top ranks for post-OpenAI AI push

NEW YORK, December 30, 2025, 16:04 ET — After-hours Microsoft shares closed slightly higher on Tuesday after a report said Chief Executive Satya Nadella has reshuffled parts of the company’s senior leadership as it tries to sharpen its artificial intelligence push beyond OpenAI. Financial Times+1 The moves matter now because Microsoft’s AI strategy is increasingly judged on execution — turning data-center spending and developer tools into sustained cloud growth — while rivals step up their own offerings. The Financial Times said Nadella’s changes were aimed at speeding progress on Microsoft’s own models and product rollouts. Financial Times Macro added another
Micron stock pulls back from record close as Fed minutes, AI memory crunch stay in focus

Micron stock pulls back from record close as Fed minutes, AI memory crunch stay in focus

NEW YORK, December 30, 2025, 4:12 PM ET — After-hours Micron Technology, Inc. shares ended down 0.6% on Tuesday at $292.74, a day after the memory-chip maker finished at a record $294.37. The stock traded between $298.53 and $292.03 during the session. The dip matters because Micron has become a key gauge for the industry’s newest bottleneck: high-bandwidth memory, a fast type of DRAM used in AI systems. The iShares Semiconductor ETF was little changed on the day. A shifting mix of demand is driving the debate. Research firm IDC said major suppliers have redirected capacity toward AI data-center parts
MongoDB stock today: MDB slips as “MongoBleed” vulnerability and patch push stay in focus

MongoDB stock today: MDB slips as “MongoBleed” vulnerability and patch push stay in focus

NEW YORK, December 30, 2025, 15:47 ET — Regular session. MongoDB, Inc. shares were down about 0.3% at $422.06 in late-afternoon trade on Tuesday, after swinging between $421.85 and $428.22 as investors digested fresh security disclosures around the database maker’s software. The issue matters now because it affects core infrastructure. “MongoBleed” is tied to CVE-2025-14847 — a standard vulnerability identifier — and involves an “unauthenticated” attack path, meaning an attacker may not need a username or password to try to pull sensitive data from a vulnerable server. The U.S. National Vulnerability Database said the flaw was added on Dec. 29
Qualcomm stock edges up as Fed minutes hit; QCOM eyes Feb. 4 earnings call

Qualcomm stock edges up as Fed minutes hit; QCOM eyes Feb. 4 earnings call

NEW YORK, December 30, 2025, 15:14 ET — Regular session Qualcomm (QCOM.O) shares were up about 0.2% at $173.75 in afternoon trading on Tuesday, hovering near Monday’s close as markets digested new details on the U.S. interest-rate outlook. That matters for Qualcomm and other semiconductor names because investors often value them like “growth” stocks, whose prices can swing when bond yields move. In year-end trading, the rate narrative can outweigh company-specific headlines. Minutes from the Federal Reserve’s Dec. 9-10 meeting — the detailed account of policymakers’ debate — showed officials split even after approving a quarter-point, or 0.25 percentage point,

Why Western Digital stock is down today: WDC slides as year-end rotation cools AI-hardware trades

NEW YORK, December 30, 2025, 3:00 PM ET — Regular session Western Digital Corp shares fell 1.7% to $176.55 on Tuesday, after opening higher and sliding through the afternoon. The stock touched $181.34 earlier in the session before dipping as low as $176.31. The pullback lands after a standout year for the data-storage maker, whose shares have surged about 303% in 2025, making it one of the S&P 500’s biggest gainers. That steep run has made the stock a frequent target for late-December portfolio reshuffling. Barron’s Broader U.S. indexes were little changed in choppy, light-volume trading, with investors repositioning inside
Rigetti stock today: RGTI steadies as Fed minutes and year-end flows keep quantum names jumpy

Rigetti stock today: RGTI steadies as Fed minutes and year-end flows keep quantum names jumpy

NEW YORK, December 30, 2025, 14:34 ET — Regular session Rigetti Computing shares edged up 0.3% to $22.34 on Tuesday afternoon, after swinging about 3% between the day’s high and low. IonQ rose 1.2% and D-Wave Quantum gained 1.6%. The muted move matters because quantum-computing stocks have become a high-beta pocket of the market, prone to sudden swings when liquidity thins and rate expectations shift. With the calendar turning, traders are re-pricing how much room the Federal Reserve has to ease in 2026. U.S. stocks were subdued in holiday-thin trading, with investors rotating within technology after a late-year run-up, Reuters
KLA stock dips as China’s 50% domestic chip-tool rule rattles semiconductor equipment names

KLA stock dips as China’s 50% domestic chip-tool rule rattles semiconductor equipment names

NEW YORK, December 30, 2025, 14:00 ET — Regular session Shares of KLA Corp fell about 0.8% to $1,250.43 on Tuesday, after a Reuters report said China is requiring chipmakers seeking approval for new or expanded plants to show at least half their equipment will be sourced domestically. The stock traded between $1,249.69 and $1,273.20. Reuters The China headline matters for KLA because chipmaking tools are a long-cycle business: policy shifts can change where fabs (chip factories) buy equipment and how quickly foreign suppliers lose share. For investors, the risk is less about one quarter and more about visibility into
AI stocks today: Nvidia AI21 buyout talk hits tape as Meta climbs on Manus deal

AI stocks today: Nvidia AI21 buyout talk hits tape as Meta climbs on Manus deal

NEW YORK, December 30, 2025, 13:31 ET — Regular session Nvidia shares were nearly flat on Tuesday after an Israeli report said the AI-chip leader is in advanced talks to buy startup AI21 Labs for as much as $3 billion. Nvidia was down about 0.02% at $188.18 in early afternoon trade. Reuters The M&A chatter is landing in a holiday-thin week when investors are reassessing crowded AI trades after a late-2025 tech rally stalled on Monday. Strategists say the rotation has looked more like year-end rebalancing than panic selling. Reuters Traders are also bracing for macro headlines that can swing
Reddit stock price today barely moves as CTO share-sale filing and AI-search thesis collide

Reddit stock price today barely moves as CTO share-sale filing and AI-search thesis collide

NEW YORK, December 30, 2025, 12:33 ET — Regular session Reddit shares were little changed on Tuesday, holding near $234.60 in midday trading, as investors digested an insider sale disclosed in a regulatory filing and a fresh round of bullish talk on the company’s role in AI-driven search. The muted move matters because Reddit has been one of the market’s standout winners since its March 2024 debut, and attention is shifting from momentum to whether the platform can keep turning AI-driven attention into ad dollars. A year-end tape that has been broadly calm leaves company-specific signals — even routine ones
Intel (INTC) stock jumps after Nvidia closes $5 billion share purchase

Intel (INTC) stock jumps after Nvidia closes $5 billion share purchase

NEW YORK, December 30, 2025, 11:30 ET — Regular session Intel shares rose 3.8% to $38.08 in morning trade on Tuesday after the chipmaker confirmed Nvidia had completed a $5 billion stock purchase. The transaction lands as Intel looks to reinforce its finances after years of missteps and capital-intensive production expansions, with the Nvidia investment seen as a key lifeline. Reuters In a Form 8-K — a filing companies use to disclose material events between quarterly reports — Intel said it issued and sold 214,776,632 shares to Nvidia for $5.0 billion in cash, or $23.28 per share, and that the

SanDisk stock today: SNDK rebounds from early dip as year-end trade thins

NEW YORK, December 30, 2025, 11:41 ET — Regular session Sandisk Corp shares rose 0.8% to $246.30 in late morning trade on Tuesday after dropping as much as 3.1% earlier in the session. The stock ranged from $236.64 to $246.84. The year-end tape has put Sandisk back on watchlists because it has been one of 2025’s biggest winners. Kiplinger recently ranked SanDisk as the S&P 500’s top gainer for the year, up about 594%, alongside storage and memory peers Western Digital, Micron Technology and Seagate Technology. Kiplinger That kind of run can cut both ways in the final week of
