China’s tech-focused ChiNext index surged more than 2% on Tuesday, hitting a significant phase high as investors poured capital into the hardware backbone of the country's burgeoning artificial intelligence sector. This rally was part of a broader upward trend in Chinese markets, with the Shenzhen Component Index rising over 1% and the Shanghai Composite gaining 0.55% as risk appetite returned to the trading floor.
The primary catalyst for the day’s performance was the "computing power" supply chain. Printed circuit board (PCB) manufacturers, memory chip designers, and optical module (CPO) providers dominated the gainers' list, with several industry leaders like Hudian and Jiangbolong hitting all-time highs. This explosive growth reflects a deep-seated market conviction in the long-term infrastructure needs of large language models and domestic digital transformation.
Beyond domestic tech sentiment, external geopolitical tailwinds provided a much-needed boost to regional sentiment. Reports of potential breakthroughs in negotiations regarding Iran’s nuclear program and regional ceasefires triggered a rally across Asia-Pacific markets, including South Korea and Indonesia. The resulting drop in global oil prices further eased inflationary concerns, allowing risk appetite to return to growth-oriented equity markets.
Market dynamics showed a clear divergence between heavyweight growth stocks and the broader market, though nearly 2,700 individual stocks finished in the green. Trading volume on the Shanghai and Shenzhen exchanges hit a massive 1.5 trillion yuan for the half-day session, signaling a return of liquidity as investors pivot away from traditional energy sectors toward what Beijing terms "New Quality Productive Forces."
