U.S. Stocks Trend (June 24): Korean Stock Plunge Ripples Global Chip Sector, Micron Tumbles Over 10%, Long-Term Supply Certainty Faces a 'Hard Test'

US Stock Market Trend (June 24): South Korean Market Plunge Disrupts Global Chips, Micron Drops Over 10%, Long-Term Supply Certainty Faces Hard Test On Monday, the South Korean KOSPI index plunged 10%, with SK Hynix and Samsung dropping over 12%, triggered by rumors that SK Hynix might slow its HBM4 production expansion. This shock quickly spread to the U.S. semiconductor sector. Micron plummeted 13.18% to $1,051.77, SanDisk fell 13.64%, and Marvell declined 8%. The Philadelphia Semiconductor Index closed down 7.87%, while the Nasdaq fell 2.21% to 25,587.04 points. The sell-off particularly hit memory chip stocks. Defensive sectors showed relative resilience, with gains in stocks like IBM and Johnson & Johnson. Market volatility spiked, with the VIX index jumping 12.79%. Commodities weakened, with WTI crude oil hitting a near three-month low and gold falling below $4,100. The core issue is not a challenge to AI demand itself, but a market reassessment of overly optimistic capacity expectations for memory chips, especially HBM. The rumor about SK Hynix undermined perceived certainty in the AI infrastructure cycle. Key upcoming events include Thursday's PCE inflation data, which will influence Fed rate expectations, and Micron's earnings report. The market will focus on Micron's HBM gross margins and its long-term capacity guidance. The shift indicates the AI investment cycle is moving from euphoria to rational pricing. Large institutions are questioning the sustainability of AI-related capital expenditure growth. Micron's repricing from an "AI infrastructure staple" to a more cyclical stock highlights this change. Thursday's data and earnings represent a critical juncture for assessing long-term supply certainty, which has now significantly decreased.

The Computing Power Dilemma in the Sino-US AI Rivalry

The Sino-US AI rivalry faces a fundamental bottleneck: the widening compute power gap. While Chinese AI chip companies have seen investment surges, their current focus remains largely on the less demanding inference market. The real challenge lies in the high-end training chip sector, crucial for developing cutting-edge large language models (LLMs), where Nvidia holds a near-monopoly. The compute disparity is stark. US tech giants like Meta, Google, and xAI command massive GPU clusters, enabling them to train trillion-parameter models rapidly. Estimates suggest US data center count and total compute capacity significantly outstrip China's. This "brute force" advantage allows for faster model iteration and exploration of larger parameter scales, with top US models reportedly leading their Chinese counterparts by 8 to 15 months. Chinese alternatives, such as Huawei's Ascend and others from companies like Moore Thread and Biren, are emerging. They show promise in inference and some training scenarios, closing the performance gap with mid-range Nvidia products. However, the core hurdle extends beyond raw chip performance to the entrenched software ecosystem, exemplified by Nvidia's CUDA platform. The path forward involves "walking on two legs": navigating import restrictions while heavily investing in the domestic chip industry. Though still in a catch-up phase, China's vast market, talent pool, and capital are fostering progress. The ultimate test is whether Chinese firms can build a competitive hardware-software ecosystem to power the next generation of AI.

Chips, Open-Source Models, and $50 Trillion: Joe Tsai Reassesses Alibaba Once Again

Alibaba Executive Chairman Joe Tsai recently outlined the company's comprehensive AI strategy in a public discussion. He believes AI represents a massive opportunity, estimating its potential economic impact at up to $50 trillion, stemming from the automation of human intelligence and productivity. Tsai detailed Alibaba's four-layer investment approach across the AI stack: starting from the chip level, moving to cloud infrastructure (Alibaba Cloud), then the model layer with its open-source Qwen model, and finally applications within its vast digital ecosystem (e-commerce, logistics, etc.). The company avoids the energy layer due to China's efficient infrastructure. This broad strategy is designed to ensure Alibaba captures value regardless of where it ultimately concentrates in the AI value chain. He dismissed concerns about an AI investment bubble, pointing to the enormous $50 trillion opportunity. While acknowledging U.S. cloud giants' higher capital expenditure, he argued Chinese firms, including Alibaba (funded by its cash-generative e-commerce core), need to invest more in AI infrastructure. A key theme was technological sovereignty. Tsai positioned open-source models like Qwen as a solution for companies, especially in Europe, seeking independence from proprietary U.S. models and greater data privacy control. He contrasted this with the trend of U.S. giants keeping their models closed-source. Tsai highlighted Alibaba's collaborations with European manufacturers like Bosch and Siemens, using AI for design and quality control. He concluded with an optimistic vision of AI agents enhancing productivity, ultimately freeing up human time for leisure, family, and experiences like live entertainment.

The 'Chip' Challenge and Breakthroughs in China's Optical Industry Chain

China's Photonics Industry: Bottlenecks and Breakthroughs In the global AI race, computing chips dominate the narrative, but the underlying bottleneck increasingly defining the scale of AI clusters is light—or more specifically, optical connectivity. Optical modules, which translate electrical signals to light and vice versa, are crucial for connecting thousands of GPUs in AI data centers, preventing data congestion and ensuring efficient model training. High-speed modules (800G, 1.6T) are now standard, with performance hinging on advanced DSP (Digital Signal Processor) chips. This is where a critical dependency lies. Two US giants—Marvell and Broadcom—collectively dominate over 90% of the high-end DSP chip market. Chinese optical module leaders like Zhongji Innolight and Eoptolink rely on these chips to manufacture modules for overseas AI customers, primarily in North America. While this creates a supply chain vulnerability, complete decoupling is difficult. Marvell derives over half its revenue from Greater China, and the US firms depend on Chinese partners for chip packaging and optical components. The risk from laser chips (e.g., from Lumentum), another key component, is considered more manageable due to multiple global suppliers and faster progress in domestic alternatives from companies like YOFC and Accelink. To mitigate risks, China's industry is pursuing a multi-pronged strategy: diversifying supply chains and locking in long-term orders; fostering a domestic market ecosystem to adopt homegrown DSPs from firms like Huawei HiSilicon and CETC; accelerating R&D in high-speed DSPs and advanced packaging; and investing in next-gen technologies like silicon photonics and Co-Packaged Optics (CPO) to reduce reliance on discrete DSPs. The ultimate solution lies not in short-term博弈 but in persistent advancement of domestic high-end chip R&D and manufacturing. While challenges remain in performance, certification, and ecosystem building, China's vast domestic market and manufacturing base provide a crucial buffer, buying time for the industry to achieve greater technological independence.

US Stock Market Trend (June 16): SpaceX Rises 42% in Two Days, New Fed Chairman Takes Office Today

**U.S. Stocks Trend (June 16): SpaceX Soars 42% in Two Days, New Fed Chair Takes Office Today** Markets surged on Monday following former President Trump's social media announcement of a completed U.S.-Iran deal to reopen the Strait of Hormuz, pending a June 19 signing. The news triggered a broad risk-on rally: oil prices crashed, tech stocks soared, bond yields fell, and defensive sectors lagged. **Market Performance:** The Nasdaq jumped 3.07%, led by semiconductor stocks like Micron (+9.2%). The S&P 500 gained 1.65%, and the Dow rose 0.92% to a record high. However, the Russell 2000 small-cap index underperformed (+0.72%). SpaceX continued its hot streak, rising another 5% pre-market after disclosures of large buys by an Australian billionaire and Cathie Wood's ARK. Boeing also rallied on the transportation optimism. Conversely, energy stocks like Chevron fell over 3% on the oil price plunge, with other defensive sectors also selling off. The day's action showed a clear rotation of funds from energy/defensive plays into AI and tech narratives. **Macro & Outlook:** The VIX fear index fell 8.37%. Treasury yields declined, and WTI crude dropped over 5%. Attention now shifts to a packed schedule: the Bank of Japan is widely expected to hike rates to 1.0% on Tuesday. The Fed's June meeting concludes Wednesday, marking new Chair Wash's debut. While rates are expected to hold, his tone on stubborn inflation and the "dot plot" will be crucial for gauging the 2024 rate path. The formal Iran deal signing is set for Friday. **Trend Perspective:** While the peace deal is a genuine positive, Monday's explosive rally may have gotten ahead of itself, pricing in a swift resolution to inflation concerns. The shortened trading week faces a triple test: BoJ tightening, the Fed's policy stance, and deal implementation details. Tech and semiconductors, which led the surge, remain vulnerable to any disappointment from these key events. The real price discovery begins with the central banks' communications this week.

How Difficult is Chip Making? A Division Error Costs 475 Million Dollars

How Hard Is It to Make a Chip? A Division Error Cost $475 Million Chip expert Shi Kan, a researcher at the Chinese Academy of Sciences and a popular tech creator, explains the immense challenges of chip development. Chips are foundational to modern technology, but their creation is extraordinarily difficult. The journey from sand to a functional chip involves complex design and manufacturing, but a critical bottleneck is verification—ensuring the design works flawlessly before costly production. A single, undetected bug can have catastrophic consequences, as illustrated by the infamous 1994 Intel Pentium FDIV bug. A flaw in the floating-point division unit forced a recall costing $475 million. Unlike software, chips cannot be easily patched after manufacture, making "first-time success" paramount. However, industry surveys show only 24% of chip projects achieve this; over three-quarters require at least one costly re-spin due to design flaws. Verification has thus become the dominant phase, consuming up to 70% of the design cycle. The core challenge is a "verification impossible triangle" between high performance, good debuggability, and low cost. Exhaustively verifying a modern CPU core could take 15,000 years with software simulation, or 30 years with advanced hardware emulation—timeframes utterly impractical for development. Despite being essential, verification is often seen as unglamorous "dirty work," receiving less academic attention than fields like AI. Shi and his team are tackling this by developing an agile verification research framework called ENCORE, based on FPGA technology, to improve verification efficiency and debug capability. Beyond research, Shi engages in public science communication through long-form video content, aiming to demystify chip technology, AI, and computer science. He argues for the value of pursuing "hard and long-term" endeavors, whether in the meticulous world of chip verification or in creating substantive educational content, believing such sustained effort is likely the right path forward.
