Microchip Technology announced a collaboration with Micron to showcase an end-to-end PCIe Gen 6 storage architecture combining Microchip’s Switchtec PCIe Gen 6 switches with Micron’s 9650 NVMe solid-state drives. The joint solution targets AI, high-performance computing, and cloud workloads by delivering greater bandwidth, lower latency, and scalable storage connectivity. Microchip’s Switchtec switches are built on a 3-nanometer process, support up to 160 lanes, and are designed for lower power consumption in high-density AI systems. The partnership strengthens Microchip’s competitive position against Broadcom and Astera Labs in the AI and enterprise data-center market, where Broadcom expects AI semiconductor revenue to reach $56 billion in fiscal 2026 and Astera Labs’ Scorpio AI Fabric Switch portfolio has entered volume production. Microchip shares have gained 21.8% year to date, and the Zacks Consensus Estimate for fiscal 2027 earnings is $3.14 per share, implying 91.46% growth.

Several stocks made big moves in after-hours trading following quarterly earnings reports. SpaceX fell 7% after releasing its first quarterly report since going public in June, despite second-quarter revenue of $7.81 billion topping an LSEG consensus of $6.93 billion. Arista Networks gained 11% after adjusted earnings of $1.02 per share on revenue of $3.04 billion beat estimates, and third-quarter guidance also surpassed expectations. AMD plunged 8% as second-quarter results and in-line third-quarter revenue guidance of $13 billion failed to impress investors. Wynn Resorts jumped 7% after adjusted earnings of $1.24 per share on revenue of $1.86 billion beat consensus. Astera Labs wiped earlier gains and was last trading lower by 4%, even as third-quarter guidance exceeded Wall Street's estimates. Kratos Defense & Security Solutions rose as much as 8% postmarket before paring that advance, with second-quarter revenue beating estimates in all segments. Pinterest slid 8% after third-quarter revenue guidance of $1.19 billion to $1.21 billion merely met the FactSet consensus. DaVita fell over 6% despite better-than-expected second-quarter results, as full-year adjusted earnings guidance of $14.10 to $15.20 per share compared to a $14.88 consensus. Teradata slumped 17% after third-quarter earnings guidance of 55 to 59 cents per share trailed the 62-cent estimate. Booking Holdings advanced more than 5% after second-quarter gross bookings of $51 billion and adjusted earnings of $2.54 per share topped estimates.

Astera Labs shares have surged 70% this year but face a pullback ahead of its second-quarter earnings report on Aug. 4, prompting caution despite strong AI infrastructure demand. The company reported first-quarter revenue of $308 million, up 93% year over year, and guided for second-quarter revenue between $355 million and $365 million. However, the stock trades at 93 times forward earnings, and one customer accounted for more than 70% of revenue in 2025, highlighting concentration risk. Competition from larger firms like Broadcom and Marvell Technology adds pressure, making it prudent to wait until after earnings to assess guidance and customer diversification progress.

Chinese AI company Moonshot has unveiled Kimi K3, an open-source AI model that rivals the most advanced systems from US leaders OpenAI and Anthropic while being cheaper to run, triggering a stock market slump and fears over US tech supremacy. The model, which is the world's largest open AI model by parameter count, costs $0.95 per intelligence index task compared to $1.04 for OpenAI's most advanced model, according to Artificial Analysis. Moonshot paused new subscriptions on Sunday after demand overwhelmed its servers, and separately Alibaba announced it is preparing to launch a new version of its open-source Qwen model. The releases come as President Xi Jinping promotes Chinese AI across the developing world, with 29 countries recently signing up to a China-led AI cooperation organization. Analysts warn the strategy could undermine US business models and extend Beijing's influence, while security experts raise concerns over the open availability of such powerful capabilities.

Zacks Investment Research compares Astera Labs and Amphenol, concluding that Amphenol is the stronger connectivity stock pick. Astera Labs reported first-quarter 2026 revenue of $308 million, up 93% year over year, with PCIe Gen 6 contributing more than one-third of total revenue, but faces near-term profitability pressure from elevated spending. Amphenol booked a record $9.4 billion in orders in the first quarter of 2026, with a book-to-bill ratio of 1.24:1, and saw defense sales rise 44%, industrial sales rise 52%, and commercial aerospace grow 22% year over year. Amphenol carries a Zacks Rank #2 (Buy), while Astera Labs holds a Zacks Rank #3 (Hold).

Astera Labs shares fell 12.33 percent to $362.05 on Tuesday, extending losses for a second day as re-escalating US-Iran tensions and profit-taking weighed on investor sentiment. President Donald Trump announced over the weekend a reinstated blockade on Iran in the Strait of Hormuz, which dampened markets despite his clarification that other countries' cargoes would pass freely. The Nasdaq dropped 1.55 percent, the S&P 500 lost 0.79 percent, and the Dow Jones shed 0.26 percent. The decline also followed a late-month surge after Astera Labs was added to the Nasdaq-100 index effective June 22. The company expects second-quarter revenue between $355 million and $365 million, implying 15 to 18 percent growth from $308.4 million a year earlier, and will report results after market close on August 4, 2026.

The S&P 500 fell 0.67%, the Dow dropped 0.38%, and the Nasdaq 100 slid 2.14% to a one-week low, driven by a sharp selloff in semiconductor stocks after Samsung Electronics' blowout earnings failed to impress. Samsung, the world's largest memory maker by market value, closed down more than 8% in South Korea even after profit surged 19-fold, as investors question whether massive AI spending can be sustained. The iShares Semiconductor ETF fell to a four-week low and dropped more than 6%, with Astera Labs and Sandisk down more than 11%, Western Digital down more than 10%, and Applied Materials, Intel, Lam Research, and Marvel Technology down more than 9%. A jump in crude oil prices following attacks on shipping near the Strait of Hormuz also weighed on stocks, with WTI crude up more than 2%, boosting inflation expectations and pushing the 10-year Treasury yield to a three-and-a-half-week high of 4.52%. The US May trade deficit widened to $77.6 billion, the largest in 14 months, adding to negative sentiment, while New York Fed President John Williams said inflation is still quite high. Strength in software stocks provided some support, with Thomson Reuters up more than 5% and Workday and Atlassian up more than 4%.

Grow Funds highlighted Astera Labs in its first-quarter 2026 investor letter, noting that while the semiconductor connectivity provider’s revenue and earnings continue to grow, the rates of growth are decelerating. The firm stated that Astera Labs had run up due to AI demand to a price-to-earnings multiple of over 57 times 2026 earnings, a level it deemed unsustainable. Astera Labs shares closed at $417.07 on June 18, 2026, with a one-month return of 40.08% and a 52-week gain of 361.86%, giving it a market capitalization of $71.49 billion. The number of hedge fund portfolios holding the stock rose to 53 at the end of the first quarter from 52 in the prior quarter.
