China’s A-share market has entered a period of profound fragmentation, where the euphoria of a technological revolution masks a deepening malaise across the broader economy. While nearly 600 companies surged to record highs in May, the reality for the average investor was far grimmer, with almost 4,000 stocks ending the month in the red. This disparity illustrates a market where institutional capital is no longer betting on a broad-based recovery but is instead seeking refuge in a select few high-growth narratives.
At the heart of this trend is the extreme clustering of massive funds into the artificial intelligence sector, a phenomenon known locally as 'baotuan.' For fund managers, AI represents a rare pocket of certainty in an environment otherwise clouded by sluggish domestic consumption, property market woes, and global interest rate volatility. This concentration has created a self-reinforcing loop where rising leaders attract more capital, forcing the liquidation of laggards to meet redemption pressures.
The scale of this imbalance is startling when viewed through the lens of historical benchmarks. By late May, over 2,000 stocks were trading at prices lower than when the Shanghai Composite Index sat at the 3,000-point mark over a year ago. While the headline indices appear resilient, nearly 40% of the market has effectively decoupled from the index gains, as traditional bellwethers in pharmaceuticals, machinery, and consumer goods suffer from a steady 'bloodletting.'
Trading data highlights this extreme concentration, with a mere 5% of listed companies accounting for nearly half of the total market turnover. Dominant players in the AI supply chain—specifically in optical modules, printed circuit boards, and advanced packaging—have seen their valuations swell to record levels. For these tech giants, the global explosion in compute demand provides a tangible earnings backbone that traditional sectors currently lack.
Despite the clear evidence of overcrowding in tech trades, a pivot to undervalued 'old economy' sectors remains elusive for most investors. Analysts suggest that a meaningful rotation requires a fundamental shift in macroeconomic sentiment, such as a stabilized property market or a significant rebound in consumer confidence. Until such triggers emerge, the market is likely to remain a tale of two extremes, where the AI sector sizzles while the rest of the board continues to smolder.
