Changes in Hong Kong stocks | Puyuan Precision Electronics (00537) rose more than 25% in the intraday period, AI computing power construction pushes high-speed interconnection to accelerate upgrades, vector network analyzers are expected to welcome opportunities

The Zhitong Finance App learned that Puyuan Precision Electronics (00537) rose more than 25% in the intraday period. As of press release, it had risen 17.53% to HK$27.36, with a turnover of HK$135 million.

According to the news, AI computing power construction is driving the accelerated upgrading of high-speed interconnections, and vector network analyzers (VNA) are expected to usher in development opportunities. Huatai Securities believes that with the evolution of data center networks to 800G and 1.6T, the requirements for signal integrity and yield control of high-speed connectors, cables, and high-end PCBs continue to increase, driving the increase in demand for VNA testing; at the same time, upgrading to higher frequencies, more ports and automation is expected to drive VNA volume and price to rise sharply. I am optimistic that domestic manufacturers will use the accumulation of RF microwave technology and continuous product iteration to achieve growth in the context of downstream demand expansion and domestic substitution.

According to public information, in October 2025, Puyuan Precision released the DNA 5000/6000 series vector network analyzer, providing a frequency range from 5 kHz to 26.5 GHz. In the first half of this year, Puyuan Precision achieved operating income of about 487 million yuan, an increase of 37.15% over the previous year; net profit attributable to shareholders of listed companies was about 37.1477 million yuan, an increase of 129.08% over the previous year. The increase in revenue was mainly due to the steady increase in sales of electronic measuring and testing instruments such as digital oscilloscopes and the increase in sales revenue of solutions during the reporting period.
