Top 20 U.S. Stock Trading Volume on August 1: Amazon's strong earnings report drives stock price up over 15%

On Friday, Micron Technology, the top stock by trading volume in the U.S. market, closed down 5.90%, with a trading volume of $46.056 billion. The stock has fallen 10.63% this week and 28.70% in July. However, it still maintains an increase of over 180% year-to-date.

Apple, the second highest, closed down 7.35%, losing over $350 billion in market value, with a trading volume of $40.175 billion. The stock dropped more than 7% on Friday due to performance outlooks being dragged down by memory shortages, marking its largest single-day decline since April 2025.

The company’s fourth-quarter revenue guidance growth range is 9%-11%, overall below analysts' expectations of 12.1%. During the earnings call, Apple CFO Parekh stated that component supply constraints will impact the iPhone, Mac, and iPad businesses in the fourth quarter, and currency fluctuations are also limiting growth.

Amazon, ranked third, closed up 15.32%, with a trading volume of $34.608 billion. The stock recorded its largest single-day increase since 2012. This surge was driven by its cloud business, Amazon Web Services (AWS), which saw a year-on-year revenue growth of 36.7% in the second quarter, reaching $42.2 billion, exceeding market expectations and achieving the fastest growth rate in 18 quarters.

Analysts pointed out that AWS has finally achieved the long-awaited growth inflection point, and Amazon is at a fundamental turning point, with both the pace and profitability of its capital expenditure digestion phase better than market concerns. Amazon CEO Andy Jassy stated that AWS is "very likely" moving towards a target of $1 trillion in annual revenue. However, analysts expect AWS revenue for fiscal year 2026 to be $169.7 billion, indicating a significant gap.

Amazon CFO Brian Olsavsky mentioned during the earnings call that AWS's profitability is not coincidental but stems from discipline, efficiency improvements, and capacity optimization, while the company consistently controls fixed costs.

The impressive performance of AWS and the management's earnings guidance were described as "exceeding everyone's expectations." The market showed confidence in Amazon's ability to convert capital expenditures into financial returns, driving a strong rebound in the stock price.

Microsoft, ranked fourth, closed up 3.02%, with a trading volume of $27.927 billion. The stock surged 15.5% in Thursday's trading, marking the largest single-day increase since the company went public, and also the largest single-day market value increase in U.S. stock market history. This remarkable performance was due to the company’s fourth-quarter fiscal year 2026 earnings report released after the market closed on Wednesday, which comprehensively exceeded expectations and effectively dispelled market concerns about the difficulty of monetizing large investments in AI.

Investors were further pleased to see Microsoft demonstrate restraint in capital expenditures. The capital expenditure for the quarter was $41 billion, below the expected $42 billion; the company expects capital expenditures for fiscal year 2027 to be approximately $175 billion, down from the previous estimate of $190 billion, and did not significantly raise expenditure guidance like Alphabet and Meta. The free cash flow for the quarter still reached $19 billion, showing better financial discipline than some competitors The 6th place SanDisk fell 5.09%, with a transaction volume of $26.516 billion. The stock has accumulated a decline of 15.43% this week and a drop of 46.57% in July.

The 8th place Google Class A shares rose 6.73%, with a transaction volume of $16.304 billion. Google DeepMind launched the next-generation robotic AI model Gemini Robotics 2, achieving full-body control of humanoid robots for the first time, with actions such as walking, squatting, reaching out, and manipulating objects all completed by the same model, which can also autonomously plan multi-step tasks and collaborate with other robots.

Three models were released: Gemini Robotics 2 is responsible for converting camera images and natural language instructions into action control; Gemini Robotics ER 2 is responsible for understanding the environment, communicating with people, planning multi-step tasks, and coordinating robots to complete work; Gemini Robotics On-Device 2 can run directly on the robot device, reducing reliance on network connections. Gemini Robotics ER 2 is now available to developers through the Gemini API and Google AI Studio, while the other two models are initially open to early partners.

The 13th place Intel fell 1.02%, with a transaction volume of $9.745 billion. The stock has accumulated a decline of 2.3% this week, marking the sixth consecutive week of losses. Recently, it was reported that TSMC is developing AI chip packaging technology to directly compete with Intel.

According to two individuals familiar with the project, TSMC is developing an advanced chip packaging technology that benchmarks against Intel's existing solutions. This also indicates that the world's top foundry is wary of the pressure from distant competitors.

Chip packaging is the final stage of chip manufacturing: assembling multiple independent silicon chips into a whole and completing circuit interconnections to achieve collaborative work while interfacing with the overall hardware. Packaging was once considered a routine process in chip manufacturing, but with the explosive demand for AI computing power, chip manufacturers need to integrate more processors and high-bandwidth memory into the packaging, resulting in larger sizes and more complex structures. Packaging has now become one of the most prominent capacity bottlenecks in the entire industry.

The 15th place SK Hynix fell 3.54%, with a transaction volume of $6.855 billion. The stock has accumulated a decline of over 7% this week.

The 20th place Marvell Technology rose 2.32%, with a transaction volume of $5.121 billion. On Friday, U.S. stocks in the optical communication sector continued to rise collectively. However, in the recently concluded July, Marvell accumulated a decline of over 37%.
