The Shanghai Composite opened 0.20% lower at 3,881.74 points, whereas the Shenzhen Component opened 0.11% higher, the ChiNext opened 0.35% higher, and the STAR 50 opened 0.07% higher.

Dragged by a sharp drop in international crude oil prices overnight, the oil and petrochemical sector along with coal led declines among Shenwan's first-tier industries. In contrast, paper manufacturing, biotech, passenger vehicles, and industrial metals showed resilience and moved against the trend.

Overnight developments saw US stocks close higher on August 25, with the Dow Jones rising 0.30%, the S&P 500 gaining 0.32%, and the Nasdaq advancing 0.66%. NVIDIA climbed 2.19%, snapping a seven-session losing streak. As the US shifted toward sanctions-based pressure on Iran and expectations rose for the resumption of navigation through the Strait of Hormuz, WTI crude futures tumbled 3.12% to $82.36 per barrel, while Brent crude fell 3.89% to $88.58 per barrel.

In domestic monetary policy news, the People's Bank of China conducted 500 billion yuan in one-year Medium-term Lending Facility operations on August 25, with 600 billion yuan maturing that month, resulting in a net withdrawal of 100 billion yuan. Additionally, the central bank announced on August 24 that it would conduct overnight reverse repurchase operations from August 27 to September 1, with daily operations capped at 600 billion yuan.

The interim earnings reporting season entered its peak period, with a flurry of results released on the evening of August 25. Wus Printed Circuit (Kunshan) Co., Ltd. reported a 73.72% year-on-year surge in first-half net profit, Jiangxi Copper Company Limited saw net profit jump 106.77%, and China Merchants Securities Co., Ltd. posted a 104.87% increase in net profit. Meanwhile, the State-owned Assets Supervision and Administration Commission convened a meeting on August 20 to advance 6G initiatives among central state-owned enterprises, focusing on technological breakthroughs and accelerating the path toward commercial deployment.

Looking at today's trading outlook, the four major indices opened with mixed signals—the Shanghai Composite dipped 0.20% while the Shenzhen Component, ChiNext, and STAR 50 all opened modestly higher, reflecting the weaker-Shanghai, stronger-Shenzhen pattern. With US stocks closing higher overnight and NVIDIA breaking its losing streak, sentiment in optical communications and memory storage sectors may see a boost, potentially lifting tech and growth stocks. However, the more than 3% plunge in international oil prices is likely to weigh on resource-heavy sectors such as oil and petrochemicals and coal, putting pressure on the Shanghai index.

Domestically, the central bank's 500 billion yuan MLF operation and the announced overnight reverse repo arrangements for the end of the month provide liquidity support. Strong interim results in optical communications and PCB sectors underpin the fundamentals of the computing power supply chain. Institutional consensus leans toward power equipment exports and high-demand computing power as relatively favorable directions, with no signs of systemic negative feedback in capital flows. In the near term, resource sectors may face headwinds, while tech growth and pharmaceutical consumer segments could see relatively active trading, with the broader indices likely to continue their oscillating and divergent pattern.
