On Tuesday, the stock with the highest trading volume in the US market was Micron Technology, closing up 4.92% with a turnover of $29.718 billion. Wall Street institutions forecast that Micron and the broader chip sector will generate approximately $700 billion in profits by 2027. Among them, Micron is seen as the most dramatic growth story. Despite a share price decline exceeding 4% last month, its net profit for the 2025 fiscal year is a modest $9 billion. However, it is projected to surge to $83 billion in FY2026 and further reach $176 billion in FY2027.

The core driver behind this explosive profit growth is the persistently strong demand for high-end memory chips, such as High Bandwidth Memory (HBM), fueled by artificial intelligence. This demand, coupled with computing acceleration from products like NVIDIA GPUs, supply tightness, and multi-year customer contracts, has directly led to significant upward revisions in its long-term profit forecasts.

However, the recent share price weakness has spread from Micron to peers like Samsung. This growth trajectory is contingent on factors including sustained high levels of AI capital expenditure, robust memory chip pricing, and a measured pace of new capacity additions. JPMorgan notes that the tight supply environment is expected to persist, with no large-scale new capacity expected to come online before early 2028.

The second most actively traded stock was NVIDIA, which closed up 4.06% with a turnover of $25.761 billion. According to media reports, NVIDIA is considering a collaboration with Mitsubishi Heavy Industries in the field of AI data center technology. The plan involves integrating Mitsubishi's cooling systems and energy management technology into NVIDIA's next-generation data centers.

The report stated that NVIDIA is positioning its next-gen AI data centers as "AI factories" and plans to establish these facilities with global partners. Concurrently, Mitsubishi Heavy Industries is also designing its own next-generation data center, "DIAVAULT," specifically for AI, and is actively developing and validating liquid cooling systems for data centers.

The third on the list was SanDisk, closing up 5.01% with a turnover of $16.759 billion. Despite SanDisk's share price having corrected 28.3% from its all-time high on June 25, Wall Street analysts remain broadly optimistic about its prospects.

Goldman Sachs analyst James Schneider raised his price target to $2,200, anticipating that large cloud computing orders will drive its 2026 earnings to be nearly 30% above expectations.

Wedbush analyst Matthew Bryson noted that strong demand and constrained supply growth in the memory sector are benefiting both Micron and SanDisk.

Evercore ISI analyst Amit Daryanani was even more bullish, significantly raising his price target to $3,100, arguing that the market is underestimating the sustainability of its earnings. He estimates the company's business model ensures a baseline revenue of $62 billion for the coming years, with over $11 billion in financial guarantees enhancing visibility.

Among 29 analysts, 23 hold a bullish rating, with the average price target rising to $2,325.83. The company is scheduled to report its Q4 FY2026 earnings on August 5.

The fourth most traded stock was IBM, which plunged 25.21% in its worst single-day decline in the company's 115-year history. The turnover was $14.663 billion, erasing $69 billion in market value. Prior to this, the company's largest single-day drop occurred on October 19, 1987, "Black Monday," when it fell 23.7%.

The company released preliminary second-quarter results before the market opened on Tuesday, showing both revenue and profit fell short of market expectations. CEO Arvind Krishna acknowledged the company failed to adapt swiftly enough to a sharp shift in customer spending patterns.

Krishna admitted the company's response to rapid market changes was inadequate, with several large deals failing to close within the expected timeframe, constituting a significant portion of the earnings shortfall. He stated these situations required flawless execution, and the team fell short this quarter.

The fifth spot went to SK Hynix, which soared 27.29% with a turnover of $12.499 billion. In related news, top research firm SemiAnalysis published a report titled "Be Greedy When Others Are Fearful: SK Hynix's DRAM Pricing & Profits Remain Strong," indicating that SK Hynix's DRAM profits for Q2 2026 and beyond will remain robust. The firm expects the DRAM blended average selling price (ASP) to increase approximately 45% sequentially, with DRAM operating profit projected to reach about 55 trillion Korean won, significantly above many market consensus estimates.

Ranking tenth was Intel, closing up 4.50% with a turnover of $9.681 billion. Intel recently announced a €5 billion (approximately $5.7 billion) investment in Ireland to upgrade its Irish campus and expand its European manufacturing capacity.

Intel stated this expansion will upgrade existing facilities and install state-of-the-art manufacturing equipment. This will aid in the delivery of Intel Xeon 6 processors and the next generation of Intel Xeon processors, strengthening the European semiconductor supply chain to meet growing global demand for AI and high-performance computing.

The majority of this investment is expected to be deployed by the end of 2027, accounting for roughly 30% of Intel's $17 billion capital expenditure plan for 2026. It is projected to create hundreds of new jobs.

Ranking fourteenth was Oracle, which fell 2.74% with a turnover of $6.584 billion. Some analysts pointed out that investor concerns over Oracle's high debt levels and execution risks associated with major projects, including a $300 billion deal with OpenAI, have led to a downgrade of its credit rating.

Market worries primarily focus on two areas. First, Oracle is advancing a $300 billion data center construction partnership with OpenAI, a massive investment plan that would significantly increase the company's debt burden. Second, investors are skeptical about Oracle's ability to effectively execute such a large-scale infrastructure expansion.

The nineteenth spot was taken by JPMorgan Chase, which rose 2.50% with a turnover of $5.214 billion. JPMorgan Chase reported record quarterly profits for the US banking industry.

The bank's second-quarter earnings release showed net profit surged 41.2% year-over-year to $21.16 billion, or $7.70 per share, far exceeding analyst expectations of $5.59 per share and setting a new record for the highest quarterly profit in the history of US banking.

The core driver of this massive earnings beat was a broad-based surge in markets and investment banking revenue. Total revenue for the quarter reached $57.35 billion, well above expectations of $51.09 billion. Specifically, equity markets revenue soared 86% year-over-year to $6 billion, while investment banking revenue increased 45% to $3.9 billion. Consumer & Community Banking revenue grew 7.6%, and Asset & Wealth Management revenue increased 18.9%, with all business segments reaching record highs.

The company's CEO stated that high market activity was the primary driver of performance, but "years of continued investment and prudent capital deployment" also laid the groundwork for the outperformance. Concurrently, the bank raised its full-year net interest income guidance from the previous $103 billion to $105.5 billion.
