On May 19, 2026, China’s financial markets marked the 27th anniversary of the legendary “5.19” rally of 1999. While both periods represent seismic shifts in A-share sentiment fueled by policy support and technology, the current '9.24' rally—which began in September 2024—reveals a fundamental evolution in China’s economic DNA. Unlike the speculative fever of the dot-com era, today’s market is underpinned by a global artificial intelligence boom and a desperate, state-mandated push for domestic semiconductor sovereignty.
The 1999 rally was a creature of liquidity and narrative. Spurred by aggressive regulatory easing and a desire to bolster the nascent internet sector, the Shanghai Composite Index surged 70% in just six weeks. However, that era was characterized by 'concept' trading; most companies lacked stable business models, and the rally ultimately collapsed under the weight of liquidity tightening and the global burst of the dot-com bubble. It was a market of hope rather than hardware.
Fast forward to 2026, and the landscape is unrecognizable. The current '9.24' cycle has seen the ChiNext Index soar by over 147%, driven by tangible demand for AI infrastructure. Leading firms in optical modules and AI chips, such as Zhongji Innolight and Cambricon, have seen their share prices breach the thousand-yuan mark. This 'Performance Bull' is rooted in China’s deep integration into the global AI supply chain, even as it navigates a decoupling landscape.
A stark divergence has emerged within the market, signaling a structural transition in the Chinese economy. While AI-related stocks in communication and electronics continue to reach record highs, traditional 'white horse' stocks—the consumer darlings of the 2019-2021 era like Kweichow Moutai and Wuliangye—are languishing. Nearly 10% of the market is trading below their prices from the start of the rally in September 2024, highlighting a brutal rotation from old-school consumption to new-school tech.
However, the echoes of 1999 remain in the form of valuation risks. With over 60 stocks now trading at price-to-earnings ratios exceeding 1,000, market analysts are warning of local overheating. While the industrial foundation is significantly more robust than it was 27 years ago, the extreme concentration of capital into a few high-growth sectors suggests that the bull market may be entering a volatile late-stage phase where performance must finally catch up to increasingly stretched expectations.
