China's ChiNext Index Nears Record Crossover on 1,500% Stock Surge

A rally in technology shares is pushing China’s growth-oriented ChiNext Index toward a historic crossover above the Shanghai Composite Index, a move analysts say signals a definitive pivot to new-economy assets. The tech-heavy index is being driven by a boom in artificial intelligence stocks, with some component makers surging as much as 1,500% over the past year.

"The ChiNext Index is expected to achieve a complete transcendence of the Shanghai Composite Index in this round," Wang Jun, a strategist at BOC International Securities, said in a May 10 report. The analysis argues the market is witnessing a fundamental repricing of economic drivers, not a repeat of a brief crossover in 2021 that quickly reversed.

The divergence is stark. In the week of May 4-9, the communication and electronics sectors led gains in the A-share market, while traditional sectors like petroleum and coal lagged amid an 11.4% weekly drop in Brent crude prices. Within the AI theme, capital targeted specific sub-sectors with tangible growth, pushing optical module stocks up 12.1% and AI programming shares up 15.7%. The ChiNext Index itself hit a nearly 11-year high of 3,785.23 on April 23.

At stake is whether the durable profit growth from AI and advanced manufacturing can decisively eclipse a sluggish recovery in China’s old economy. A sustained move by the ChiNext above the Shanghai Composite would suggest investors are confirming that the nation's new growth engines now command a higher weight in asset allocation, reshaping the logic for the entire A-share market.

New Economy Earnings Outpace Old Guard

Unlike the 2021 peak, which was fueled by a broad, stimulus-led demand cycle that ultimately faltered, the current rally is built on more specific and sustainable earnings trends. Analysts argue that the price-to-earnings ratio of the ChiNext relative to the Shanghai Composite remains significantly below its 2021 high, suggesting the move is backed by profit fundamentals rather than speculative froth.

The core of the bull case rests on "hard tech" sectors where China is seeking self-sufficiency and global competitiveness. This includes AI infrastructure, domestic semiconductors, and optical components. Optical chipmaker Yuanjie Semiconductor Technology, for example, saw its shares surge roughly 1,500% over the past year. This performance reflects a new "Chinese-style" valuation framework investors are applying to strategic industries, prioritizing long-term technological breakthroughs over short-term profitability metrics.

Policy is reinforcing this trend. In April, regulators relaxed listing standards for the ChiNext board, opening the door to unprofitable but strategically important technology firms. This is expected to draw more new-economy companies to the index, further solidifying its identity as the benchmark for China's growth narrative.

Capital Flows Target Hard Tech

Fund flow data reveals a highly concentrated bet on this theme. In the most recent week, A-share markets recorded a net main-force capital inflow of 154.3 billion yuan, the second straight week of inflows and a four-week high. The buying was narrowly focused, with the electronics sector attracting 54.1 billion yuan and the communication sector drawing 36.4 billion yuan.

Conversely, broad-based stock ETFs saw net redemptions of 75.9 billion yuan, marking the ninth consecutive week of outflows. This divergence shows that investors are not making a blanket bet on Chinese equities but are actively rotating capital out of diversified holdings and into specific high-conviction technology themes.

While the AI narrative is strong, some investors warn that the crowding could lead to a sharp correction of 30% to 50% if earnings lag behind lofty expectations or if overseas demand for tech components weakens. Still, the primary thesis holds that the market is undergoing a structural re-rating. The question is no longer if the new economy will lead, but by how much.
