On Thursday, the top stock by trading volume was Micron Technology, closing up 4.52% with a turnover of $40.84 billion. The company announced its plan to invest more than $250 billion in the United States by 2035. This latest plan represents a significant increase from the $200 billion target it announced in June of last year.
According to Micron, the purpose of this additional investment includes achieving a long-term goal of producing 40% of its DRAM (Dynamic Random Access Memory) output domestically within the US.
The $250 billion investment will be allocated to several factory construction projects, such as building a second cutting-edge memory chip fabrication plant in Boise, Idaho, and expanding a manufacturing facility in Manassas, Virginia. Additionally, tens of billions of dollars will be directed towards technology research and development.
Included within this investment plan, Micron also announced its intention to invest up to $3 billion in the US to strengthen the domestic semiconductor supply chain ecosystem, build critical semiconductor manufacturing capabilities necessary for future technological innovation, and meet the growing demand for advanced memory driven by AI and other data-intensive applications.
Of this $3 billion, $500 million is strategic financing support provided to GlobalWafers. This financing will be used to advance the development and capacity building of GlobalWafers America's 300mm prime silicon wafer manufacturing facility in Sherman, Texas. The two companies also signed a ten-year supply agreement to ensure Micron secures sufficient prime silicon wafer capacity.
Furthermore, according to Micron, the company and GlobalWafers also plan to collaborate on next-generation wafer technology and process innovation.
The second-ranked stock by volume was Nvidia, closing down 0.66% with a turnover of $26.485 billion. Nvidia recently released the open-source large model Nemotron 3 Ultra, which has garnered market attention for its high performance and extremely low inference costs. The model achieved the highest accuracy rate in its category on the LangChain Deep Agent benchmark among open-source models, while its inference cost is only one-tenth that of leading closed-source industry models.
Nemotron 3 Ultra has a total of 550 billion parameters, with 55 billion activated per token. It employs a Mixture of Experts (MoE) architecture, integrating Mamba-2, MoE, and attention layers, and incorporates multi-token prediction technology to enhance inference speed. The model supports a context window of up to 1 million tokens and is optimized for scenarios such as complex agent workflows, long-context analysis, and multilingual reasoning.
The third-ranked stock was SanDisk, closing up 7.59% with a turnover of $24.499 billion. US memory-related stocks generally rose on Thursday.
The fourth-ranked stock was Meta Platforms, closing up 4.70% with a turnover of $15.503 billion. The company's CEO, Mark Zuckerberg, stated that Meta requires as much computing power as possible. However, given the supply shortage of computing resources needed for AI development and operation, he is also considering whether leasing part of its AI infrastructure to external customers could create more value.
Zuckerberg said, "Currently, the market bid for computing power is very high. In some cases, it might be more economical to lease it out or consider similar transactions rather than keeping it for internal use."
Earlier this month, media reports indicated that Meta is planning to launch a cloud computing business, hoping to generate direct revenue by leveraging its data centers and other computing power partners. Zuckerberg stated that the opportunity to develop a cloud business "has always been there, and we can do it anytime we want."
The sixth-ranked stock was Tesla, closing up 3.17% with a turnover of $14.68 billion. According to several Tesla supply chain sources, Tesla has recently issued specific procurement guidance for Optimus robot components, requiring suppliers to ramp up capacity to 1,000 units per week by September this year, and then increase it to 2,000-2,500 units per week by the end of the year.
Two individuals close to suppliers stated that Tesla places orders approximately two months in advance, and they have already seen specific orders for hundreds of units in August.
Based on this estimate, Tesla's suppliers will have the capacity to supply components for 100,000 Optimus units annually to Tesla by year-end.
Reports also indicated that before placing orders with the supply chain, during an executive review meeting at the end of June, Elon Musk approved the latest version of Optimus. This means that after more than three years of development, Optimus Gen 3 is finally set to leave the laboratory and enter mass production.
The seventh-ranked stock was AMD, closing up 5.67% with a turnover of $14.656 billion. AMD confirmed it will launch the Zen 6 processor on July 22.
The tenth-ranked stock was Broadcom, closing up 3.20% with a turnover of $11.005 billion. Apple announced it has signed a new multi-year cooperation agreement with chip manufacturer Broadcom, with an estimated total value exceeding $30 billion, which will drive the production of over 150 billion chips in the United States. This is the largest commitment since the launch of Apple's "Made in America" initiative.
Under the agreement, Broadcom will undertake a $1.5 billion capital upgrade and modernization expansion at its facility in Fort Collins, Colorado, to produce advanced radio frequency components (including FBAR filters) and wireless connectivity technologies, providing cellular, Wi-Fi, and Bluetooth connectivity support for various Apple products.
This collaboration is a key part of Apple's previously announced four-year, $600 billion US economic investment plan, aimed at boosting domestic manufacturing, creating jobs, and fostering technological development. In a filing with the US Securities and Exchange Commission this past Monday, Broadcom disclosed that the two parties have signed a new long-term technology cooperation agreement, extending the partnership term to 2031 and covering the development and supply of custom ASIC silicon products for multiple generations of Apple products.
The thirteenth-ranked stock was Applied Materials, closing up 3.18% with a turnover of $8.44 billion. Applied Materials CEO Gary Dickerson stated that chip manufacturers are now extending their equipment demand forecasts to two years or even longer, with some customers planning horizons extending to 2030.
He believes this forward-looking planning provides sufficient confidence for equipment manufacturers like Applied Materials to expand their production capacity in an orderly manner, without needing to frequently adjust their pace due to the uncertainties of the semiconductor cycle as in the past.
The seventeenth-ranked stock was Marvell Technology, closing up 4.99% with a turnover of $5.156 billion. Marvell Technology recently raised its growth forecast for its interconnect business for fiscal year 2027 and plans to begin sampling 1.6T optical modules in 2026, with industry capital expenditure showing a promising upward trend.
The company had previously raised its growth expectation for this business in fiscal 2027 to over 70%, and it remains to be seen whether this target will be met. The company plans to start sampling within 2026, and feedback from sampling and subsequent orders will be important catalysts.
