On June 2, the three major Chinese stock indices experienced a rebound, with the ChiNext Index rising by 2.66%.
Today's market action displayed a significant divergence between major indices and individual stocks. While the ChiNext Index surged over 2.6%, the number of declining stocks far exceeded gainers, representing an extreme case of a sector-specific rally. The primary catalyst stemmed from the AI computing power supply chain. Comments from NVIDIA's CEO, Jensen Huang, at the Taipei Computex event, emphasizing the critical role of high-speed connectivity in the era of distributed AI computing and revealing deepened collaboration with Marvell on next-generation data center network architecture, directly ignited investment enthusiasm in the optical communications sector. Consequently, capital became highly concentrated in niche areas like optical communications and CPO (Co-Packaged Optics), leading to significant volume-driven gains in leading stocks and propelling the ChiNext Index sharply higher. However, most other sectors remained lackluster due to an absence of catalysts, and previously high-flying stocks continued to face selling pressure.
The earlier correction in the technology and growth sectors likely resulted from natural profit-taking after periods of excessive trading concentration. This phase may now present a potential window for re-evaluation and reallocation. Since late May, the tech sector has faced overall pressure, primarily due to rising U.S. Treasury yields weighing on valuations, excessively high trading concentration in certain areas, and recurring geopolitical tensions fueling risk aversion. However, underlying industry fundamentals remain robust: investment in AI infrastructure continues to accelerate, the rollout of 1.6T technology is speeding up, and the optical communications sector stands to benefit from data center architecture upgrades, potentially providing a foundation for a shift from expectation-driven to earnings-validated performance. In the short term, external macroeconomic uncertainties persist, and the sector may require a period of consolidation following its rapid ascent. Nevertheless, its medium-term investment value remains clear, warranting moderate attention to specialized leaders with strong technological moats and visible order pipelines.
Looking ahead, structural divergence is likely to characterize the near-term market trend. The intense focus of capital on the AI computing chain may struggle to broaden across the entire market in the short run. While indices like the ChiNext and STAR Market offer high elasticity, they remain susceptible to fluctuations in external liquidity expectations and geopolitical developments. On a macroeconomic level, May's PMI data indicated a widening gap between supply and demand, suggesting the foundation for economic recovery is not yet solid. A sustained recovery in overall market risk appetite requires further confirmation from fundamental indicators. Strategically, it is advisable to maintain controlled overall position sizing while focusing allocations on technology sub-sectors demonstrating earnings delivery capability. This approach should be balanced with exposure to reasonably valued defensive assets to navigate the prevailing market divergence and volatility.
