Sector performance showed notable divergence, with non-metallic materials (+9.63%), electronic chemicals (+5.56%), glass and fiberglass (+5.36%), electronic components (+5.09%), semiconductors (+4.54%), and crop farming (+4.39%) leading the gains. On the downside, photovoltaic equipment (-2.33%), condiments and fermented products (-1.96%), home appliances (-1.56%), power grid equipment (-1.21%), major state-owned banks (-1.16%), and baijiu (-0.80%) recorded losses.
Market Drivers
The three major indices posted solid gains on the day, with the STAR 50 Index surging 3.77% to lead the market. The Shanghai Composite rose 1.13%, the Shenzhen Component gained 1.50%, and the ChiNext advanced 1.71%. Approximately 61% of all listed stocks advanced, and combined turnover on the two exchanges reached roughly 2.1259 trillion yuan, expanding by about 317.24 billion yuan from the previous session.
Computing hardware-related sectors led the rally, with PCB and copper-clad laminate concepts strengthening notably. Stocks including Jinneng Anji, Hongchang Electronics, and Yangtze Optical Fibre hit their daily limit. The catalyst came from Nvidia's overnight disclosure of fiscal 2027 second-quarter revenue of approximately $96.2 billion, up 106% year-over-year, along with guidance for next-quarter revenue of $108 billion at the midpoint, representing a nearly 90% year-over-year increase.
The storage chip segment also gained momentum, with Dmli hitting the daily limit and Dapu Microelectronics surging 20%. Dapu Micro announced on August 26th that it secured a $515 million sales order for enterprise-grade PCIe SSDs. Additionally, South Korea's DRAM export unit prices surged 401% year-over-year, providing further tailwinds for the sector.
Agriculture and food-related concepts maintained their strong momentum, with Xinjiang Tianshan Cotton, Wandelnong, Jinjian Rice, and Xinsai Shares all hitting their daily limits. Global food price indices rose for the third consecutive month in July, while the global corn inventory-to-consumption ratio fell to its lowest level in nearly a decade.
Gold-related concepts moved higher, with Shenzhen Zhongjin Lingnan extending its winning streak to six consecutive daily limits. In contrast, photovoltaic equipment led the decline, with Sungrow Power dropping 12.24% following the U.S. President's executive order on August 26th prohibiting federal procurement of certain foreign-made large power grid equipment.
Leading Sectors in Focus
1. Computing Hardware: PCB and copper-clad laminate concepts surged across the board, with the CCL segment jumping 7.92%, electronic components rising 5.09%, and non-metallic materials gaining 9.63%. Jinneng Anji, Xiehe Electronics, and Hongchang Electronics hit their daily limits, while Shengyi Electronics advanced 14.32%. Kexiang and Zhongying Technology both rose over 10%, and Lianrui New Materials gained 20%. The catalysts included Nvidia's strong earnings report and robust half-year profit growth from multiple PCB supply chain companies including Hengtong Optic-Electric, Shennan Circuits, and Tianjin Printronics.
2. Storage Chips: The storage chip concept strengthened, with the semiconductor sector gaining 4.54%. Dmli hit its daily limit, while Dapu Micro and Sai Microelectronics both surged 20%. Hangsuh, Montage Technology, Lianyuntech, and X-raychip all advanced over 6%. The catalysts included Dapu Micro's $515 million enterprise PCIe SSD order and South Korea's DRAM export prices jumping 401% year-over-year. Additionally, Samsung Electronics and SK Hynix plan to increase supplies of 8-layer HBM4 memory to Nvidia in the second half of the year.
3. Crop Farming: The farming and food concepts continued their strong run, with the crop farming sector gaining 4.39%. Xinnong Development, Xinsai Shares, Jinjian Rice, and Wandelnong all hit daily limits, while Qiule Seeds, Nongfa Seeds, and Yasheng Group followed with gains. The catalysts included the global food price index reaching 131.1 points in July, marking its third consecutive monthly rise, and the global corn inventory-to-consumption ratio falling to 17.9%, the lowest in nearly a decade. The UK Met Office also forecast that this year's El Ni帽o could be the strongest since modern meteorological records began.
Underperforming Sectors
Photovoltaic equipment, condiments and fermented products, home appliances, power grid equipment, banking, and baijiu sectors led the declines. Photovoltaic equipment fell 2.33%, ranking as the worst-performing Shenwan secondary industry sector. Major state-owned banks dropped 1.16% and joint-stock banks declined 1.10%, while baijiu slipped 0.80%. In the photovoltaic segment, Sungrow Power plunged 12.24% with turnover reaching 14.13 billion yuan. The trigger was the U.S. President signing Executive Order 14420 on August 26th, which prohibits federal procurement or installation of certain foreign-made large power grid equipment and related software (including battery energy storage systems) on national security grounds.
