Today, August 27th, all three major A-share indices climbed more than 1%, with trading volume rebounding to the 2.1 trillion yuan level.
Influenced by Nvidia's better-than-expected earnings, the AI hardware supply chain saw broad gains across the board. More than 3,300 companies rose, creating a solid profit-making effect in the market.
In early trading, the Shanghai Composite Index opened slightly lower, while the Shenzhen Component Index and the ChiNext Index opened marginally higher. From there, the market moved collectively upward, closing with all three indices gaining over 1%.
The Shanghai Composite rose 1.13%, once again challenging the 4,000-point mark. The Shenzhen Component Index gained 1.50%, reclaiming the 14,000-point level. The ChiNext Index advanced 1.71%.
In terms of turnover, the market recorded approximately 2.1 trillion yuan in trading volume, a significant increase of about 317.2 billion yuan compared with the previous session. Volume expanded notably, returning above the 2-trillion-yuan threshold, signaling a clear recovery in market activity.
At the individual stock level, 3,394 companies advanced while 1,944 declined, 212 were flat, 78 hit the daily limit up, and only 4 hit the daily limit down. With over 60% of stocks rising, the market showed a favorable profit-making environment.
At the sector level, AI hardware exploded higher on the back of Nvidia's earnings beat. Technology stocks rallied while some traditional sectors pulled back.
Where the gains concentrated
Nvidia's fiscal 2027 second-quarter results showed revenue of approximately $96.221 billion, up 106% year-over-year and 18% quarter-over-quarter. GAAP net income reached $59.688 billion, up 126% year-over-year and 2% sequentially. Non-GAAP net income came in at $53.954 billion, up 118% year-over-year and 18% quarter-over-quarter.
Nvidia's strong performance has validated, to some extent, the underlying logic of AI infrastructure investment. Memory chip stocks continued their upward run, with 德明利 and 大普微 hitting their daily limit up. 长鑫科技 surged 5.38%, and 兆易创新 added 4.76%.
The PCB sector strengthened across the board, with 肯特股份 hitting the daily limit up and 生益电子 jumping 14.32%. CPO (co-packaged optics) names oscillated higher with widespread limit-ups, including 赛微电子, 长飞光纤, and 星网锐捷, all closing at their daily limit.
In short, AI hardware rose broadly, with 海光信息, 浪潮信息, 工业富联, and 沐曦股份 all posting significant gains today.
Traditional sectors show mixed performance
Outside of AI tech, the agriculture sector continued its strong run, with 万向德农 posting a third consecutive limit-up and 金健米业 logging its sixth limit-up in nine days. 新农开发 and 新赛股份 also hit the daily limit up.
Nonferrous metals and precious metals performed well too, with 深中华A extending its streak to six consecutive limit-ups and 湖南黄金 hitting the daily limit. The securities sector carried over its prior-day strength, with 湘财股份 achieving a second consecutive limit-up.
On the downside, the banking sector pulled back collectively, with 华夏银行, 民生银行, and 浙商银行 all falling over 2%. The baijiu sector was notably weak, as the CSI Baijiu Index slipped 0.67%. 贵州茅台 dropped 0.81%, 洋河股份 fell 2.58%, and 五粮液 declined 1.08%.
The photovoltaic equipment sector led the declines, with 阳光电源 plunging 12.24%. Power grid equipment names also weakened, with 思源电气 hitting the daily limit down.
Market outlook
Overall, today's market delivered a volume-driven rally, with turnover expanding significantly from the prior session and reclaiming the 2-trillion-yuan level. AI tech staged a full-blown comeback, returning to the spotlight.
Driven by Nvidia's better-than-expected quarterly results, the AI hardware supply chain exploded higher, with computing hardware, memory chips, PCB, and semiconductor sectors all surging. Meanwhile, traditional sectors like banking and baijiu entered a consolidation phase.
