Main Topic
Over the most recent seven-day period from July 31 to August 6, margin financing activity on China’s A-share market displayed a clear rebalancing pattern, with overall leverage levels recovering and sector rotation evident among lenders and borrowers. The aggregate financing balance rose back above the CNY 2.6 trillion threshold, reaching CNY 26,155.66 billion. During the same period, net purchases funded by margin accounts totaled CNY 36.177 billion, signaling renewed risk-on positioning among leveraged investors.
At the industry level, the electronics sector led inflows, with margin-financed net buys exceeding CNY 10 billion—specifically CNY 13.785 billion—as investors rotated into areas benefiting from accelerated AI adoption, data-center expansion, and components supply-chain upgrades. Several other sectors also recorded meaningful positive financing flows: non-ferrous metals, computer-related industries, and power equipment each received net inflows in excess of CNY 3 billion, reflecting diversified bullishness across cyclicals and technology-related industrial suppliers.
Conversely, the financing side also saw concentrated net repayments. Petroleum and petrochemical, steel, transportation, and diversified conglomerates experienced net margin repayments larger than CNY 100 million each; the largest of these was petroleum and petrochemicals with CNY 457 million in net repayments. Such outflows suggest reallocation from traditional cyclical names into higher-growth or seasonally favored technology exposures during that week.
On a single-stock basis, 25 companies saw net margin purchases exceeding CNY 300 million. Leading inflows were concentrated in AI chip and PCB-related names. Cambricon (寒武纪) topped the list with an extraordinary CNY 3.181 billion of net margin purchases for the week. Other notable beneficiaries included Shenghong Technology, China Ping An, and C JLC (C嘉立创), which attracted CNY 754 million, CNY 599 million, and CNY 517 million respectively. Additional significant inflows were recorded for CATL, Guotai Haitong, Xiechuang Data, and Hikvision, each exceeding CNY 400 million.
The surge in financing interest for certain semiconductor and PCB names is supported by company-level catalysts and broader market dynamics. Cambricon released its 2026 semiannual results on August 7, reporting first-half revenue of CNY 5.996 billion, a year-on-year increase of 108.13%, and net profit attributable to shareholders of CNY 2.311 billion, up 122.61%. Management attributed the rapid growth to expanded market penetration and the accelerated rollout of AI applications that leverage the company’s chip portfolio. Brokerage coverage has emphasized Cambricon’s leadership in domestically developed AI processors, ongoing R&D into next-generation microarchitectures and ISA support, and deeper adaptation with local large models—factors that underpin a positive medium-term growth thesis.
Shenghong Technology and the newly listed C JLC belong to the PCB (printed circuit board) sector, which has become a hotspot amid growing demand for high-layer-count, high-density interconnect boards used in AI accelerators, servers, and high-performance compute applications. Analyst notes highlight C JLC’s manufacturing capability—PCB stacks up to 64 layers and mainstream process proficiency—while its recent fundraising is directed at multi-layer PCB production lines. Forecasts suggest the company’s PCB business could generate roughly CNY 3.884 billion in revenue in 2025, accounting for close to 40% of total revenue, with electronic components contributing a similar share.
Shenghong’s stock has enjoyed dramatic gains, appreciating by over 55% since July 31, as the company highlights mass production of high-end PCB products for AI compute, data centers, and HPC markets. Management points to two sources of future revenue growth: upgrades and mix shifts on existing lines, and volume ramp from newly built capacity. Industrywide data from Prismark projects the global PCB market value to reach USD 85.152 billion in 2025 (a year-on-year rise of 15.75%) and to approach USD 123.348 billion by 2030, reflecting a compound annual growth rate of around 7.7%.
Beyond AI chips and PCBs, several memory-related and tungsten-industry leaders—such as ChangXin Memory and Lianqi (澜起科技), as well as Xiamen Tungsten and Zhongwu High-tech—also drew margin-financing interest during the week, indicating diversified investor appetite across both upstream materials and component makers tied to AI and data-center supply chains.
Not all large-cap, high-growth companies attracted fresh financed buying. Data shows five stocks experienced net margin repayments exceeding CNY 300 million in the week. These were New H3C (新易盛) with CNY 1.539 billion in net repayments, followed by Dongshan Precision, Tsinghua Unigroup, Huaneng Hydropower, and Yongding, with net repayments in the hundreds of millions. Net lending outflows for specific names can reflect short-term profit-taking by leveraged accounts, portfolio rebalancing into hotter themes (e.g., AI chips, PCBs), or differential expectations about near-term earnings momentum.
New H3C, despite significant net repayments, reported robust first-half results and outlooks: management estimated 2026 H1 net profit attributable to shareholders in the range of CNY 7.0 billion to 8.0 billion, up roughly 77.56%–102.93% year-on-year. The company cited continued growth in AI-related compute investment, product portfolio optimization, and broad-based demand for higher-bandwidth modules. Operationally, 800G modules have become a primary shipped product, and 1.6T modules showed clear sequential volume gains in the quarter, with further acceleration expected in the second half. Silicon photonics adoption is rising, and capacity expansions in Chengdu and Thailand are being executed against forward order visibility.
In summary, the week’s financing map indicates a rotation toward technology and component names benefiting from AI and data-center expansion, while some previously favored names experienced margin repayments as investors took profits or rotated exposure. The divergence between strong company fundamentals and temporary financing outflows underscores the difference between underlying operational momentum and short-term leveraged positioning dynamics.

Looking forward, margin financing flows will likely continue to mirror investor expectations for AI-driven demand and supply-chain expansion in high-performance computing, while also reacting to short-term valuation shifts and profit-taking. Key variables to watch include order-book visibility for semiconductor and PCB manufacturers, the pace of data-center and AI infrastructure deployments, and macro liquidity or regulatory developments that could affect leverage appetite. For investors, distinguishing between transient financing rotations and durable operational improvements will be essential when evaluating market signals and positioning for the months ahead.
