On July 2, the three major Chinese stock indices experienced declines, with the Shanghai Composite Index falling over 2% and the ChiNext Index dropping more than 5%.
The A-share market saw a broad-based correction today. The ChiNext Index fell over 5% and the STAR 50 Index declined more than 7%, with the communications and electronics sectors leading the losses. This was primarily driven by a confluence of external industry narrative shifts and internal capital flows. Overnight news indicated that Meta Platforms, Inc. is planning to sell its surplus AI computing power and model access to external clients. This move directly challenges the market's previous core narrative of "extreme computing power scarcity," raising deep investor concerns about a potential AI computing power glut and whether tech giants' capital expenditures are nearing a peak. This shock led to a sharp single-day drop of over 6% in the Philadelphia Semiconductor Index, with the resulting pessimistic sentiment spilling over into the A-share market, significantly dampening domestic risk appetite. Compounding this, the technology sector in A-shares had seen substantial gains year-to-date, leading to an accumulation of floating profits. Core segments like semiconductors and optical modules were at historically high levels of trading congestion. Under the resonance of these multiple factors, the previously high-flying AI computing power and semiconductor sectors became the main targets of selling pressure.
The recent correction in the technology sector results from a combination of industry narrative reassessment, valuation digestion, and sentiment unwinding. Meta's potential move to sell computing power has prompted the market to re-evaluate the AI computing power supply-demand dynamic. If computing power transitions from "scarce" to "surplus," not only will purely conceptual stocks face pressure, but leading companies in specific segments that received high valuations based on order expectations will also confront pricing logic adjustments, as their stock prices may already reflect overly optimistic expectations for sustained prosperity. Currently, the market remains divided on whether AI infrastructure construction is approaching an inflection point. In the short term, the technology sector may face overall pressure. The depth and duration of this adjustment will require monitoring subsequent marginal changes in capital expenditure guidance from major cloud providers and the progress of AI commercialization revenue realization.
Looking ahead, the market may continue its pattern of volatile consolidation in the near term. From a capital flow perspective, the adjustment in the technology sector has been accompanied by a noticeable shift of funds into lower-positioned sectors like non-bank finance and healthcare. However, it remains to be confirmed whether this style rotation is driven by oversold rebounds or signifies a comprehensive trend reversal. Looking forward, mid-year earnings previews will become a critical window for assessing the quality of various sectors. Directions with strong earnings certainty are likely to gain greater capital recognition. Strategically, it is advisable to maintain a long-term focus on the technology theme while moderately controlling position sizes in the short term. Investors should concentrate on sub-sectors with demonstrable earnings delivery capabilities and pay attention to potential opportunities in lower-positioned sectors, adopting a balanced allocation to navigate near-term volatility.
