Main Topic
This week, capital flows in the market pointed to a shift in investor positioning. Semiconductor equipment and lithium-battery-related companies became prominent destinations for main-fund investment, while some previously popular areas of the artificial-intelligence supply chain—including optical modules, printed circuit boards (PCBs), and memory—continued to weaken. The contrast between inflows and outflows highlights how quickly market attention can rotate between industry themes.
On the inflow side, semiconductor equipment manufacturer Advanced Micro-Fabrication Equipment Inc. China (中微公司) ranked first across the market, with a net main-fund inflow of 31.68 billion yuan. Its share price rose 18.86% over the week. Contemporary Amperex Technology (宁德时代), a leading lithium-battery company, followed with a net inflow of 27.9 billion yuan and a weekly gain of 9.14%. Another major semiconductor equipment producer, Naura Technology Group (北方华创), received 21.63 billion yuan in net inflows, while its shares advanced 16.97% during the week.
These figures placed semiconductor equipment and the battery industry among the week’s most visible investment themes. The inflows were not limited to the three largest recipients. Semiconductor equipment companies Piotech (拓荆科技) and CFET (中科飞测) each attracted more than 12 billion yuan in main-fund inflows. Their participation suggests that buying interest extended across several companies in the equipment segment rather than being confined to a single stock.
Other companies also recorded substantial net inflows. Semiconductor manufacturer Semiconductor Manufacturing International Corporation (中芯国际) and clean-energy company Sungrow Power Supply (阳光电源) each received more than 16 billion yuan. Sungrow’s shares rose 25.55% over the week. Hygon Information Technology (海光信息), Tongfu Microelectronics (通富微电), and Kexiang Technology (科翔股份) each attracted more than 10 billion yuan in net main-fund inflows. Taken together, the weekly data showed strength in both the semiconductor equipment chain and the new-energy chain.
The picture was markedly different in parts of the AI-related supply chain. Optical modules, PCBs, and memory companies faced renewed concentrated selling. Four companies—ChangXin Technology (长鑫科技), Innolight (中际旭创), Tianfu Communication (天孚通信), and Victory Giant Technology (胜宏科技)—recorded combined net outflows exceeding 100 billion yuan. This aggregate outflow was a prominent feature of the week’s market activity and underscored the contrast with the funds moving into equipment and battery names.
Memory company ChangXin Technology had the largest individual net outflow in the market, at 38.88 billion yuan. Its shares fell 3.33% over the week. Innolight, a leading optical-module company, recorded a net outflow of 34.53 billion yuan and a weekly decline of 18.99%. Tianfu Communication and Victory Giant Technology saw net outflows of 22.12 billion yuan and 18.72 billion yuan, respectively; both stocks fell by more than 10% during the week.
Large net selling also affected companies beyond those four names. China Merchants Bank (招商银行), Foxconn Industrial Internet (工业富联), Wus Printed Circuit (沪电股份), Montage Technology (澜起科技), GigaDevice Semiconductor (兆易创新), and Shengyi Technology (生益科技) each recorded weekly net main-fund outflows of more than 11 billion yuan. Shengyi Technology and Wus Printed Circuit each declined by more than 16% over the same period.
These market-flow figures describe reported buying and selling activity during the week; they do not, by themselves, explain why investors made those decisions. A net outflow can reflect shifting expectations, portfolio adjustments, profit-taking, or other factors, and it should not be treated as a definitive judgment about a company’s longer-term prospects. Similarly, a net inflow or rising share price does not establish that a trend will continue. The central observation is the sharp divergence in weekly positioning: capital favored semiconductor equipment and battery-related names while several AI-linked optical, PCB, and memory stocks faced heavy net selling.
Weekly price performance also varied within the broader themes. The semiconductor equipment companies named in the inflow data generally posted gains, while the companies experiencing the largest outflows recorded declines. Sungrow’s 25.55% advance stood out among the inflow leaders, whereas Innolight’s 18.99% weekly fall and the greater-than-16% declines in Shengyi Technology and Wus Printed Circuit highlighted the pressure on several outflow-heavy stocks. These comparisons provide context for the flows, but they should not be interpreted as proof that fund activity alone caused the price changes.
Overall, the week’s activity was characterized less by a uniform move across technology stocks than by a rotation among specific industry segments. Semiconductor equipment and new energy attracted notable funding, while selected companies associated with AI infrastructure and data-related hardware saw significant withdrawals. Investors assessing this shift may wish to distinguish between individual company performance, broader sector sentiment, and the short-term movement of capital rather than treating these as interchangeable signals.

The week’s fund flows point to several areas worth monitoring, but they also demonstrate why short-term market data needs careful interpretation. Further analysis could examine whether the interest in semiconductor equipment and new-energy companies persists across multiple reporting periods, and whether selling in optical modules, PCBs, and memory represents a temporary adjustment or a broader change in market expectations. Comparing flow data with company disclosures, operating results, industry demand, and valuation measures would provide a more complete picture than any single week’s figures.
As technology supply chains develop, investors and researchers may also benefit from exploring how demand for computing infrastructure connects with semiconductor manufacturing capacity, advanced packaging, memory, and power systems. Better, more consistent disclosure of market-flow methods and time periods could help readers distinguish reported trading activity from longer-term fundamentals. Careful cross-sector research, transparent data, and attention to risk are essential when interpreting rapid changes in capital allocation.
