ChiNext Index rallies 100% year-on-year, outpacing Hong Kong’s Hang Seng Tech as investors flock to AI hardware and battery innovators. Mainland-listed CATL, the global lithium-ion leader, surged 90% after beating earnings estimates, while optical-device makers Innolight (+800%) and Eoptolink (+800%) reflect booming demand for semiconductor infrastructure. ChiNext’s AI-centric composition, including Zhongji Innolight (Nvidia’s key supplier), contrasts sharply with Hang Seng’s e-commerce-advertising stalwarts like Tencent and Baidu, which face margin pressures.

Hang Seng Tech’s 4% decline stems from reliance on China’s post-pandemic consumption recovery, complicated by price wars in sectors like food delivery. Bloomberg data shows its forward earnings estimates dropped 26% since July, while ChiNext’s rose 42% post-June lows. The gap, per Edmond de Rothschild’s Xiangdong Bao, hinges on earnings visibility: ChiNext’s hardware focus aligns with global AI and energy transition trends, whereas Hang Seng’s diversified portfolio struggles with cyclical demand.

Regulatory shifts boost ChiNext: ChiNext-linked futures, approved this month, attracted fund flows, per BNP Paribas’ Jason Lui. Unlike broad CSI futures, ChiNext offers tech-specific exposure, drawing bets on China’s AI-driven growth. However, CATL alone accounts for 20% of ChiNext’s weighting, raising volatility risks if sentiment shifts.

While Innolight’s 263% profit jump underscores sector strength, experts warn ChiNext’s top-heavy structure could amplify downturns. “It’s not speculation—it’s earnings-driven,” said Gavekal’s Leonid Mironov, though he cautioned, “a correction would hit hard.” Investors now weigh ChiNext’s resilience against its concentration risks as AI adoption accelerates.
