This week, A-shares maintained an upward trend, with major indices continuing their strong performance. Market sentiment improved significantly, and trading volume remained high, providing a favorable environment for identifying structural investment opportunities. In terms of index performance, the SSE Index(000001) rose 0.84% for the week. The index is currently 7.22% and 13.41% above its 50-day and 200-day moving averages, respectively, indicating a healthy technical picture. The CSI 300(000300) gained 2.71%, reaching a new yearly high, reflecting clear fund inflows into large-cap sectors. Growth-style indices stood out, with the ChiNext(399006) surging 7.74% for the week—hitting a new annual high and rebounding over 90% from its one-year low—highlighting strong investor focus on technology and innovation industries. The Shenzhen Index(399001) rose 4.36%, also setting a new yearly high. In the Hong Kong market, the Hang Seng Index(HSI) declined 1.03%, suggesting capital is more concentrated in the A-share market.
U.S. markets saw modest gains. The S & P 500 Index(0S&P5) rose 0.54%, reaching a new yearly high, while the Nasdaq Composite(0NDQC) advanced 0.97%, with tech stocks continuing to provide core support. U.S. initial jobless claims for the week ended August 23 came in at 229,000, below the previous week’s figure, indicating resilience in the labor market. EIA data showed that U.S. crude oil inventories fell by 2.392 million barrels for the week ended August 22, reflecting robust energy demand and providing short-term support for international oil prices. Although the inflation indicator most closely watched by the Fed may have risen for a third consecutive month, the market still expects a high probability of a rate cut in September, creating a favorable global liquidity environment for emerging market capital flows. Geopolitically, U.S. Vice President Vance indicated potential new sanctions on Russia, meaning geopolitical conflict risks remain a potential source of market disruption.
On the policy front, positive signals continue to emerge. The State Council’s Executive Meeting reiterated efforts to expand domestic demand, with fiscal and financial policies supporting the “two new” initiatives. The central bank injected 60 billion yuan in MLF on a single day and significantly expanded its net liquidity injection for August, guiding banks to increase credit lending. Additionally, major financial institutions such as PICC have clearly stated plans to increase equity investment allocations, providing strong support for market risk appetite. The construction of China’s national carbon market has also received significant policy backing, with the General Offices of the CPC Central Committee and the State Council issuing documents to promote green and low-carbon transformation, drawing investor attention to carbon asset management. At the same time, technology sectors such as artificial intelligence, computing power platforms, and domestically developed operating systems (e.g., the release of Galaxy Kylin V11) are fully benefiting from increased policy support, becoming core focal points in the capital markets.
At the sector level, the Telecom-Fiber Optics(G3552IG.CN) industry performed the most prominently this week, recording a weekly gain of 22.33% and emerging as the market’s strongest sector. This industry benefits from the ongoing expansion of data center construction and high-speed network demand, combined with bandwidth upgrades driven by AI computing power demand. Capital has flowed in significantly, with leading stocks showing substantial gains. Meanwhile, the Computer-Networking(G3574IG.CN) sector also performed strongly, rising 12.8%, as market attention on cybersecurity, cloud computing, and AI infrastructure continues to grow, driving valuation recovery for related companies. The Consumer Prod-Electronic(G3651IG.CN) sector ranked third with a 9.25% gain. Despite short-term volatility in some individual stocks, the overall trend remains positive, supported by improving demand for wearable devices and smart home products. The concentrated strength in these sectors confirms that capital is accelerating into technology and consumption upgrade-related areas, with market style gradually shifting toward growth and innovation-focused sectors.
The average gain among the TOP33 stocks this week was 8.78%, with 26 stocks rising, indicating that the structural rally is concentrated in high-growth sectors. Among them, EverProX Technologies Co Ltd(300548) was the top-performing stock in the TOP33 this week, with its share price rising 39.07%. The company specializes in integrated optoelectronic devices for optical communications and possesses proprietary core technologies, placing it at the forefront domestically in high-end passive and active optical components. It has an RS Rating of 99, an EPS Rating of 87, and operates in an industry ranked 11—indicating a high-growth, high-demand sector—reflecting strong alignment between capital flows and industry trends.
In the coming week, market focus will shift to earnings season. Approximately 624 companies are expected to report earnings, which will likely lead to market divergence. The degree of earnings realization will be key to determining whether sector strength can continue. Domestically, ongoing policy measures in carbon markets, green energy, and real estate optimization will continue to support market risk appetite. On the external front, potential new U.S. sanctions on Russia warrant attention for their potential impact on market sentiment.
Overall, the A-share market continues its upward trajectory, driven by policy support and capital inflows, with technology and high-growth sectors leading performance. In the short term, investors should monitor earnings verification during the reporting season and fluctuations in the external macro environment. However, with capital, policy, and industrial trends aligning, structural market opportunities are expected to persist.
