Applied Materials and Lam Research lead chip equipment rebound on AI memory demand; Super Micro tumbles 8% on Taiwan raids, SOXX +4.1%

Applied Materials Inc. surged 10.8% and Lam Research Corp. jumped 8.4% on Monday as chip equipment stocks mounted their sharpest single-day rebound in weeks, lifting the VanEck Semiconductor ETF 4.14% to 614.35 and confirming a broad return to AI infrastructure names after last week's selloff. Super Micro Computer Inc. fell 8.1%, the session's biggest decliner, after reports that Taiwanese authorities had raided facilities linked to an investigation into the alleged smuggling of Nvidia AI chips into China. The S&P 500 gained 1.18% to 7,440.43 and the Nasdaq Composite rose 2.07% to 25,820.14, supported by easing US-Iran tensions and Alphabet Inc.'s debut as a Dow Jones Industrial Average component.

Today's biggest movers

Applied Materials surges 10.8% on six new AI memory chipmaking systems

Applied Materials Inc. (NASDAQ: AMAT) closed at $694.64, up 10.82%, after Jefferies raised its 12-month price target to $770 from $510 and maintained a Buy rating while Bank of America lifted its target to $720 from $540. Both firms cited the company's disclosure of six new chipmaking systems targeting high-bandwidth memory, a segment growing in parallel with AI accelerator demand from hyperscalers and cloud providers. AMAT has now returned 158% over the past month, the strongest performance in the tracked chip-equipment cohort. Shares had retreated to $626.84 on Friday after a brief intraday record spike to $669.22 the prior session; Monday's close fully erased that pullback.

The move extends the chip-equipment surge from Thursday, when Applied Materials and Lam Research led the sector following Micron Technology's blowout quarterly results, and partially reverses Friday's sector retreat when chip equipment was the week's biggest laggard.

Lam Research gains 8.4% as Cantor Fitzgerald highlights market-share leadership

Lam Research Corp. (NASDAQ: LRCX) climbed 8.39% to $410.91. Cantor Fitzgerald raised its price target to $500 from $425, maintaining an Overweight rating and noting that Lam is capturing the most market share among peers in semiconductor capital equipment. Bank of America and Wells Fargo separately lifted their targets to $480 and $450, respectively, pointing to record quarterly earnings and a higher full-year wafer fabrication equipment outlook for 2026. Lam's 29.14% one-month gain and 122% year-to-date return place it among the strongest performers in the tracked universe.

Palo Alto and CrowdStrike surge on AI security demand and Wells Fargo upgrade

Palo Alto Networks Inc. (NASDAQ: PANW) added 9.14% to $332.00, extending a run that has taken the stock approximately 90% higher over the past three months. Multiple analysts pointed to strong third-quarter execution across revenue and annual recurring revenue, combined with accelerating demand for AI-powered threat detection and response as the primary drivers. The stock has now surpassed all consensus price targets published earlier this quarter.

CrowdStrike Holdings Inc. (NASDAQ: CRWD) climbed 5.96% to $742.91 after Wells Fargo analyst Michael Turrin raised his price target by 80% to $900, reiterating a Buy rating. Turrin said industry checks indicate enterprise customers are prioritizing consolidated platform security spending. CrowdStrike separately confirmed a 4-for-1 stock split effective July 2, 2026, which analysts expect to broaden the retail investor base by reducing the nominal per-share price.

Tesla soars 8.5% as AI-leveraged names stage broad Monday recovery

Tesla Inc. (NYSE: TSLA) surged 8.46% to $411.84, posting the largest gain among hyperscaler and AI-adjacent names in the tracked universe. Investors attributed the move to a broad reassessment of AI-leveraged equities after last week's pullback, alongside reports that US-Iran peace talks are scheduled to resume Tuesday - easing oil-price concerns that had weighed on risk appetite. The company is expected to report second-quarter vehicle deliveries in the coming days, with consensus estimates near 401,000 units; autonomous-driving progress and AI energy infrastructure remain the central pillars of the institutional bull case.

Super Micro tumbles 8% as Taiwan raids target alleged Nvidia chip smuggling

Super Micro Computer Inc. (NASDAQ: SMCI) dropped 8.10% to $28.15, the session's steepest decline in the tracked universe. Reports emerged that Taiwanese authorities had raided facilities linked to an investigation into the alleged smuggling of Nvidia AI chips to China. The development added fresh pressure to a stock already contending with significant shareholder dilution concerns after the company raised approximately $7 billion through equity financing earlier this month, undertaken to fulfill a backlog of roughly $39 billion in AI server orders. SMCI has now fallen 39% over the past month.

MongoDB rebounds 7.7% as Atlas growth and Q1 beat attract renewed buying

MongoDB Inc. (NASDAQ: MDB) gained 7.70% to $338.18, recovering ground lost on June 24, when the stock fell roughly 6% on AI software margin concerns. The rebound brings first-quarter results back into focus: MongoDB reported adjusted EPS of $1.32 against the $1.18 consensus and revenue of $687.6 million versus $663.8 million estimated, with Atlas cloud database growth above 29% and a remaining performance obligation pile of $1.46 billion signaling strong forward visibility. Analysts at Needham, Piper Sandler, Mizuho, and Bank of America set price targets in the $380-$410 band following the June 1 earnings call.

Notable but quieter

Taiwan Semiconductor Manufacturing Co. (NYSE: TSM) advanced 5.26% to $455.10, its strongest single-session gain in the tracked period this month, on continued demand for leading-edge capacity tied to AI accelerator production. Alphabet Inc. (NASDAQ: GOOGL) rose 4.82% to $353.65 on its first day as a Dow Jones Industrial Average component; the index inclusion followed a record-setting rally that has lifted the stock 12% year to date. Baidu Inc. (NASDAQ: BIDU) climbed 7.64% to $112.18 after reports that its AI chip subsidiary Kunlunxin is targeting a $50 billion initial public offering valuation; Citi analyst Alicia Yap maintained a Buy rating with a $188 price target on the stock, noting that AI-based revenue grew 79% year over year in the first quarter and now represents more than half of Baidu's core business. Datadog Inc. (NASDAQ: DDOG) added 3.67% to $248.57, extending a 12.69% five-session run as investors rotated back into AI observability and infrastructure software.

On the downside, Microsoft Corp. (NASDAQ: MSFT) dipped 1.18% to $368.57, the largest single-day decliner among hyperscalers, as the stock continued to consolidate after an 18% one-month correction. Oracle Corp. (NYSE: ORCL) slipped 0.52% to $147.76 and Salesforce Inc. (NYSE: CRM) fell 0.28% to $157.93, keeping enterprise software on the back foot despite the broader market rally.

What to watch

CrowdStrike's 4-for-1 stock split takes effect Wednesday, July 2, and may draw renewed retail buying at the lower nominal price. Tesla is expected to release second-quarter vehicle delivery figures in early July; the consensus near 401,000 units has become a sentiment anchor for the broader autonomy trade. Applied Materials is scheduled to report fiscal third-quarter results on August 13, with options markets implying approximately a 9% move in either direction. More broadly, the semiconductor capital equipment rally poses a durability question heading into July earnings season: Gartner forecasts total semiconductor revenue above $1.3 trillion for full-year 2026, and whether AI memory demand can sustain equipment spending at current levels will be the central variable for institutional positioning.
