The top 20 in trading volume of US stocks: Tesla soared by 11.9%, achieving its best performance in four months.

On Monday, Tesla, which ranked first in terms of trading volume in the US stock market, closed 11.93% higher, achieving its best single-day performance since November 6, with a trading volume of $44.877 billion. According to media reports, South Korean retail investors are enthusiastic about leveraged trading in US stocks. They have made a net investment of $2.2 billion in Tesla stocks this year, making it the most popular trade so far. They have also flocked to buy Palantir, NVIDIA, and a leveraged ETF that bets on US semiconductor stocks.

 

In addition, the Federal Bureau of Investigation (FBI) established a task force on Monday to address the threats faced by Tesla and investigate the attacks against the company.

 

Currently, Tesla's CEO, Elon Musk, serves as the head of the US Government Efficiency Department (DOGE). Earlier that day, the US police claimed that they had discovered several "activation" devices in Tesla's showroom in Austin, Texas; the FBI assisted the local police in their investigation at the showroom.

 

Coming in second place, NVIDIA closed 3.15% higher, with a trading volume of $27.513 billion. NVIDIA's CEO, Jensen Huang, delivered a keynote speech at NVIDIA's GTC 2025 conference held in San Jose, California, last week. He outlined the evolution of AI technology, announced the latest generation of products based on NVIDIA's Blackwell architecture, and revealed the planned shipping times for subsequent generations of products. He also disclosed the progress of NVIDIA's collaborative research and development with other tech giants in the fields of autonomous driving, AI networks, and robotics.

 

However, analysts believe that most of Jensen Huang's speech content was nothing new and did not exceed market expectations, failing to ignite investors' enthusiasm.

 

 

Meta Platforms ranked fifth, closing 3.79% higher, with a trading volume of $9.683 billion. It is reported that FuriosaAI, a South Korean AI chip startup, has rejected Meta Platforms' acquisition offer of up to $800 million and chosen to maintain its independent development. It is said that the two companies have been engaged in acquisition negotiations since the beginning of this year. Neither party has responded to the media's request for comment.

 

Amazon ranked sixth, closing 3.59% higher, with a trading volume of $7.523 billion. Amazon Web Services (AWS) has open-sourced the 5-level general-purpose AI agent framework, Multi-Agent Orchestrator. This framework can handle various complex tasks through multi-level AI agents, match users' requests with the most suitable agents for execution, and maintain context consistency and coherence throughout the interaction process.

 

Microsoft ranked seventh, closing 0.47% higher, with a trading volume of $7.934 billion. On Monday, Microsoft officially issued a product support strategy adjustment notice through the Microsoft 365 message center, confirming that technical support for OneNote for Windows 10 will be completely terminated on October 14, 2025.

 

It is reported that this means that this version will no longer receive any feature updates or security maintenance. This decision is in line with the plan to end the mainstream support for the Windows 10 operating system, jointly promoting users' migration to the Windows 11 ecosystem.

 

Strategy ranked eighth, closing 10.43% higher, with a trading volume of $7.523 billion. On Monday, US stock cryptocurrency-related concept stocks strengthened. In terms of news, Bitcoin rose to $88,000, for the first time since March 7, and has currently increased by more than 3.3% within the day.

 

In addition, it was reported on Monday that after Strategy raised over $700 million by selling so-called perpetual preferred shares, it purchased approximately $584 million worth of Bitcoin. This move is also regarded by the cryptocurrency market as the core driving force behind the recent significant rebound in the trading prices of cryptocurrencies such as Bitcoin.

 

AMD ranked tenth, closing 6.96% higher, with a trading volume of $5.997 billion. AMD announced the launch of GAIA, an open-source application specifically designed for running large language models (LLMs) locally, which currently supports the Windows platform. GAIA is a generative AI application that enables local and private operation of LLMs on Windows PCs and is optimized for the Ryzen AI 300 series processors. This application enhances the performance of AI tasks through the Neural Processing Unit (NPU) and supports the hybrid deployment of quantized LLMs.

 

Alphabet Class A shares (Google) ranked eleventh, closing 2.25% higher, with a trading volume of $5.156 billion. Analysts said that Google's recent acquisition of Wiz for $32 billion may mark the beginning of a more favorable environment for initial public offerings and trading activities. The rapid development of artificial intelligence and the transformation towards cloud computing have intensified the demand for cybersecurity solutions.

 

Micron Technology ranked fourteenth, closing 2.34% higher, with a trading volume of $3.261 billion. Micron Technology recently released its financial report, showing that its performance in the second fiscal quarter of 2025 was strong and exceeded expectations.

 

The chipmaker reported record-high high-bandwidth memory revenue due to demand exceeding supply. However, pricing pressure in the NAND flash memory and consumer market product segments caused its overall gross margin to drop to 37.9%, a quarter-on-quarter decrease of 160 basis points.

 

The company's CFO, Mark Murphy, said that the shift of the dynamic random access memory (DRAM) product portfolio towards high-value products has helped alleviate some margin pressure. However, the company expects that with an increase in the sales volume of consumer market products, the gross margin in the third fiscal quarter will decrease.

 

Needham analysts pointed out that due to the continued challenges in the NAND flash memory market and the impact of high-cost inventory, the management's forecast for the non-GAAP gross margin in the third fiscal quarter is 36.5%, lower than its own projection of 38.5% and Wall Street's forecast of 37.4%.
