On Tuesday, the storage sector in the U.S. stock market collectively plummeted. In news, Samsung Electronics released data on the 7th showing that boosted by the semiconductor supercycle and a rebound in technological competitiveness, the company's operating profit for the second quarter of this year reached 89.4 trillion won, a year-on-year increase of over 1810%, with quarterly operating profit exceeding twice that of the entire last year. Reports indicate that among global tech companies, Samsung Electronics' quarterly profit scale has surpassed historical records of companies like NVIDIA and Apple. However, despite its outstanding performance, this achievement still fails to meet the extremely high expectations of investors for Samsung, which has already been "perfectly priced" by the market. Analysts believe that although Samsung Electronics' second-quarter operating profit surged more than 18 times year-on-year, its stock price fell sharply, reflecting deep market concerns about whether the AI-driven market trend can be sustained. NVIDIA, ranked second, rose 0.71%, with a trading volume of $23.948 billion. Renowned financial commentator Jim Cramer stated on Tuesday that despite growing bearish sentiment among investors towards NVIDIA, this chip giant remains a core pillar of the current AI boom. Cramer bluntly said on the show "Street Signs": "All the main logical lines in the market still revolve around NVIDIA." "Now everyone is pessimistic about NVIDIA," he said, "but I cannot agree with the view that NVIDIA has lost its core position in the industry." SanDisk, ranked third, fell 7.26%, with a trading volume of $22.576 billion. SanDisk's fiscal year 2026 third-quarter performance was strong, with revenue of $5.950 billion, a year-on-year increase of 251%, and net profit of $3.615 billion, a year-on-year increase of 287%, both exceeding market expectations. The growth was primarily driven by the data center business, which saw revenue increase by 645% year-on-year to $1.467 billion; revenue from the edge business grew by 295% year-on-year to $366.3 million. The company's gross margin significantly improved to 78.4%. Operating cash flow reached $3.038 billion, a dramatic increase year-on-year. The company expects fourth-quarter revenue to be between $7.75 billion and $8.25 billion, currently has no debt, and has received stock buyback authorization, indicating a solid financial position. Tesla, ranked fourth, fell 4.02%, with a trading volume of $15.419 billion. According to Tesla, the number of Tesla Superchargers worldwide has surpassed 80,000. Intel, ranked fifth, fell 9.66%, with a trading volume of $15.294 billion. On Tuesday, chip stocks in the U.S. market generally declined. AMD, ranked sixth, fell 6.51%, with a trading volume of $14.817 billion. SpaceX, ranked eighth, fell 6.83%, with a trading volume of $11.99 billion. JP Morgan stated that investors underestimate the potential obstacles to a merger between Tesla and SpaceX. Analyst Rajat Gupta indicated that while a merger between Tesla and SpaceX "seems reasonable on paper," current speculation around the merger underestimates the potential barriers to the deal Gupta stated that the merger would enable CEO Elon Musk to "combine the vision, mission, and engineering leadership of the two major platforms," and the shared artificial intelligence ambitions of the two companies would serve as a "potential strategic adhesive." However, the analyst noted that potential obstacles include regulatory approvals across multiple jurisdictions; governance and voting rights symmetry; and the perception that "the merger is seen as an acquisition led by SpaceX rather than a peer-to-peer merger." He added, "Overall, we will focus on SpaceX's acquisition currency, regulatory landscape, and Musk's voting rights in Tesla as potential catalysts for the merger approaching." JP Morgan indicated that if the deal occurs, the most likely structure would be a SpaceX-led all-stock acquisition of Tesla. Gupta stated that this deal structure might best bridge the valuation gap and avoid large cash expenditures. Gupta has a neutral rating on Tesla with a target price of $475. Ranked 10th, Meta Platforms rose 2.55%, with a trading volume of $11.161 billion. Meta Platforms launched Muse Image on Tuesday, a new artificial intelligence model for creating images, as the company seeks to attract creators and advertisers. This AI technology, codenamed Mango, is the second major product released by Meta Superintelligence Labs, led by Alexandr Wang, who was responsible for the Muse Spark large language model launched in April, which replaced the company's previous Llama series models. Muse Image will be available for free to consumers through the Meta AI app and website, WhatsApp direct messages, and Instagram Stories. Advanced users and creators will need to subscribe to one of the monthly subscription plans launched by Meta in May to generate a large number of AI images and access specific features. The company stated that if users reach the free limit, they can purchase a Meta One subscription or wait for the limit to reset. Ranked 14th, Marvell Technology fell 7.45%, with a trading volume of $7.972 billion. Marvell Technology raised its growth forecast for interconnect business in fiscal year 2027 and plans to sample 1.6T optical modules in 2026, with significant industry capital expenditure growth. Ranked 16th, Crinetics Pharma rose 98.74%, with a trading volume of $6.744 billion. Fortress Biotech agreed to acquire Crinetics for $10 billion in cash, marking the largest deal in the company's history, aimed at expanding its business into the field of endocrinology. The acquisition price of $85 per share represents a 102% premium over Crinetics' closing price on Monday. The acquisition has been approved by the boards of both companies and is expected to be completed in the third quarter (Screenshot from Sina Finance APP Market - US Stocks - Stock Market Sectors Swipe for More Data) Download Sina Finance APP ### Related Stocks - [MU.US](https://longbridge.com/en/quote/MU.US.md) - [NVDA.US](https://longbridge.com/en/quote/NVDA.US.md) - [SSNGY.US](https://longbridge.com/en/quote/SSNGY.US.md) - [SNDK.US](https://longbridge.com/en/quote/SNDK.US.md) - [SMSN.UK](https://longbridge.com/en/quote/SMSN.UK.md) - [07747.HK](https://longbridge.com/en/quote/07747.HK.md) - [NVDX.US](https://longbridge.com/en/quote/NVDX.US.md) - [NVDL.US](https://longbridge.com/en/quote/NVDL.US.md) - [MULL.US](https://longbridge.com/en/quote/MULL.US.md) - [09347.HK](https://longbridge.com/en/quote/09347.HK.md) - [NVDD.US](https://longbridge.com/en/quote/NVDD.US.md) - [NVDQ.US](https://longbridge.com/en/quote/NVDQ.US.md) - [NVDU.US](https://longbridge.com/en/quote/NVDU.US.md) - [NVD.US](https://longbridge.com/en/quote/NVD.US.md) - [07388.HK](https://longbridge.com/en/quote/07388.HK.md) - [MUD.US](https://longbridge.com/en/quote/MUD.US.md) - [NVDY.US](https://longbridge.com/en/quote/NVDY.US.md) - [NVDS.US](https://longbridge.com/en/quote/NVDS.US.md) - [07788.HK](https://longbridge.com/en/quote/07788.HK.md) - [MUU.US](https://longbridge.com/en/quote/MUU.US.md) - [07347.HK](https://longbridge.com/en/quote/07347.HK.md) - [09747.HK](https://longbridge.com/en/quote/09747.HK.md) - [NVDB.US](https://longbridge.com/en/quote/NVDB.US.md) - [MAGX.US](https://longbridge.com/en/quote/MAGX.US.md) - [MUZ.US](https://longbridge.com/en/quote/MUZ.US.md) - [03121.HK](https://longbridge.com/en/quote/03121.HK.md) - [NVDG.US](https://longbridge.com/en/quote/NVDG.US.md) - [NVDO.US](https://longbridge.com/en/quote/NVDO.US.md) - [NVDW.US](https://longbridge.com/en/quote/NVDW.US.md) - [NVYY.US](https://longbridge.com/en/quote/NVYY.US.md) - [NYYY.US](https://longbridge.com/en/quote/NYYY.US.md) - [DIPS.US](https://longbridge.com/en/quote/DIPS.US.md) - [09388.HK](https://longbridge.com/en/quote/09388.HK.md) - [MUYY.US](https://longbridge.com/en/quote/MUYY.US.md) - [SNDG.US](https://longbridge.com/en/quote/SNDG.US.md) - [SNDQ.US](https://longbridge.com/en/quote/SNDQ.US.md) - [SNDU.US](https://longbridge.com/en/quote/SNDU.US.md) - [SNXX.US](https://longbridge.com/en/quote/SNXX.US.md) - [SMH.US](https://longbridge.com/en/quote/SMH.US.md) - [SOXX.US](https://longbridge.com/en/quote/SOXX.US.md) - [SOXL.US](https://longbridge.com/en/quote/SOXL.US.md) - [SOXQ.US](https://longbridge.com/en/quote/SOXQ.US.md) - [XSD.US](https://longbridge.com/en/quote/XSD.US.md) - [PSI.US](https://longbridge.com/en/quote/PSI.US.md) - [FTXL.US](https://longbridge.com/en/quote/FTXL.US.md) - [AAPL.US](https://longbridge.com/en/quote/AAPL.US.md) - [TSLA.US](https://longbridge.com/en/quote/TSLA.US.md) - [INTC.US](https://longbridge.com/en/quote/INTC.US.md) - [AMD.US](https://longbridge.com/en/quote/AMD.US.md) - [JPM.US](https://longbridge.com/en/quote/JPM.US.md) - [META.US](https://longbridge.com/en/quote/META.US.md) - [MRVL.US](https://longbridge.com/en/quote/MRVL.US.md) - [CRNX.US](https://longbridge.com/en/quote/CRNX.US.md) - [VRTX.US](https://longbridge.com/en/quote/VRTX.US.md) - [NVD.DE](https://longbridge.com/en/quote/NVD.DE.md) - [JPM-M.US](https://longbridge.com/en/quote/JPM-M.US.md) - [JPM-C.US](https://longbridge.com/en/quote/JPM-C.US.md) - [JPM-D.US](https://longbridge.com/en/quote/JPM-D.US.md) - [JPM-L.US](https://longbridge.com/en/quote/JPM-L.US.md) - [8634.JP](https://longbridge.com/en/quote/8634.JP.md) - [JPM-K.US](https://longbridge.com/en/quote/JPM-K.US.md) - [JPM-J.US](https://longbridge.com/en/quote/JPM-J.US.md) ## Related News & Research - [Nvidia Is Allegedly Delaying Its Kyber Rack-Scale Architecture by More Than 12 Months.
