Chinese mainland stocks opened strongly across the board on Wednesday, with the Shanghai Composite Index up 0.34%, the Shenzhen Component Index up 0.74%, and the ChiNext Index up 0.97% at the bell. Early momentum, however, was capped as indices pared gains following a morning push, leaving the market in a state of collective index gains, broad-based stock advances, and rapid sector rotation.

At the midday close, the Shanghai Composite Index advanced 0.35% to 3,955.85 points, the Shenzhen Component Index added 0.27% to 13,661.39 points, and the ChiNext Index rose 0.43% to 3,326.68 points. More than 4,100 stocks across the market finished the morning higher. Combined turnover for the Shanghai and Shenzhen exchanges reached 1.23 trillion yuan during the session, up 135.5 billion yuan from the previous trading day's half-day figure.

Main capital flows favored the culture media and computer sectors during the morning session, while net outflows were seen in electronics, semiconductors, and non-ferrous metals. Among individual stocks, Tianyu Digital saw net main capital inflows of over 1.2 billion yuan, ranking first, while Inspur Information experienced net outflows exceeding 900 million yuan.

Market Overview

On the upside, AI application concepts and the digital currency segment led the gains, while pork and real estate sectors displayed notable activity, with securities stocks also showing strength mid-session. On the downside, the coal sector underwent pullback adjustments, with Zhengzhou Coal Industry & Electric Power hitting the daily limit down. Precious metals retreated during the session, with Hunan Silver opening higher but declining more than 3%, and Hunan Gold falling over 2%. Semiconductors and computing hardware also eased from earlier highs.

Overall, the three major indices gave back some gains after their initial surge, yet the market maintained a broad-based rally with over 4,100 stocks advancing. Capital rotated quickly, moving out of semiconductors, computing hardware, and coal into news-driven themes like AI applications, digital currency, as well as livestock and real estate sectors.

Sector Highlights: AI Applications Surge

AI application-related stocks collectively strengthened, with Xinju Network securing its second consecutive daily limit, Longban Media achieving a fifth straight daily limit, and Yingfang Software, China Publishing & Media, and Tianyu Digital all hitting the daily limit up. Yixia Tiandi briefly touched the daily limit before easing, yet still closed the morning up over 13%. BlueFocus rose more than 7%, with culture media and software services also participating in the rally.

The catalyst came from OpenAI's official release of its new flagship model, GPT-6 Astra, on September 3 local time. Described as a "generational leap," the model is positioned as the world's most intelligent and alignment-focused AI to date, capable of directly operating within computer software environments to autonomously execute long-horizon, multi-step tasks such as programming, financial modeling, and creating presentations and spreadsheets. OpenAI President Greg Brockman noted that in hindsight, this moment may be recognized as the arrival of AGI.

Digital Currency Concepts Remain Active

Digital currency-related stocks were notably strong, with Compass (Sifang Jingchuang) hitting a 20cm daily limit; Cuixi Shares, Chutian Dragon, and Hailian Jinhui also reached their daily limits. Laka, Yusys Technologies, and Airong Software followed with gains.

The move was driven by remarks from Federal Reserve Governor Christopher Waller on September 3, signaling that if the recent disinflation trend continues, he would favor holding interest rates steady at the Fed's September meeting. This sent U.S. digital currency stocks surging overnight. Bitcoin briefly broke the $80,000 mark during the session, peaking near $81,370 per coin, its highest in nearly four months. Additionally, Compass's limit-up was tied to its role as a core partner in the m-CBDC Bridge construction, participating in cross-border application scenario research for multiple central bank digital currencies.

Pork Sector Gains Momentum

Pork-related stocks strengthened, with Tianbang Foods, Bangji Technology, and Luoniushan each hitting their daily limits, while Shennong Group, Tangrenshen, and Juxing Nongmu followed suit.

The sector's strength came as domestic hog prices rebounded in late August, driven by concentrated output reductions from major group hog producers and pre-semester canteen stockpiling. National external three-yuan standard hog quotes rose from 10.61 yuan/kg to 11.09 yuan/kg before easing from recent highs. Meanwhile, the national breeding sow inventory was trimmed to 37.8 million head at the end of Q2, just 300,000 head above the Ministry of Agriculture and Rural Affairs' normal holding target of 37.5 million head, signaling sustained capacity reduction trends.

Real Estate Sector Resumes Rally

Real estate stocks became active once again, with Cinda Real Estate achieving a third consecutive daily limit, Woaiwojia posting its fifth limit-up in nine days, and Pearl River, Shilian, and Huafa Shares all advancing.

Policy support emerged on September 3, when the Shanghai Housing and Urban-Rural Development Commission issued the "15th Five-Year Plan," promoting stable and healthy real estate market development, advancing foundational systems for real estate development financing and sales, and expediting improvements to the housing supply system—including adding 25 to 28 million square meters of new commodity housing. On August 28, multiple authorities including the People's Bank of China, the financial regulator, the Ministry of Housing, and the CSRC jointly rolled out new real estate policies, extending the maximum personal housing loan term to 40 years and promoting spot sales of commercial housing, providing ongoing policy catalysts.
