On January 30, previously hot gold stocks receded, while multiple technology-focused stocks surged strongly, such as those in computing power represented by CPO and optical communication, and semiconductors represented by memory chips. Popular stocks saw significant collective gains, with Yangtze Optical Fibre And Cable Joint Stock Limited Company hitting the daily limit-up, while Suzhou Tfc Optical Communication Co.,Ltd., Yuanjie Semiconductor Technology Co.,Ltd., and Henan Shijia Photons Technology Co.,Ltd. all experienced robust rebounds. Prices for companies like Puya Semiconductor and Zhaoyi Microelectronics accelerated to new highs.
Computing power and semiconductor stocks led the market's strong gains, with Yangtze Optical Fibre And Cable Joint Stock Limited Company closing at the daily limit-up.
On January 30, sectors within the computing power chain, such as CPO (Co-Packaged Optics) and optical communication, staged a powerful rebound, with both sectors rising over 2% for the day. Delving deeper, many individual stocks reached new highs, including Zhishang Technology (a "20cm" limit-up, reaching a historical high), Suzhou Tfc Optical Communication Co.,Ltd., Jiguang Technology, Liante Technology, and Yangtze Optical Fibre And Cable Joint Stock Limited Company.
Memory chips belong to the semiconductor industry but also represent a crucial sub-sector for computing power, serving as the core hardware for data storage in computing systems. On January 30, a group of core, high-attention memory chip stocks experienced strong gains and hit new highs, such as Jiguang Technology, Puya Semiconductor, Zhaoyi Microelectronics, and TaiJi Industry.
Behind the powerful rebound in the computing power and semiconductor industry chains lie multiple driving factors, including industrial developments and specific events. Among these, several typical logic strands stand out:
Price increases. Driven by exploding AI demand and supply-demand imbalances, the computing power and semiconductor sectors are exhibiting widespread, significant, and sustained price hike characteristics, affecting multiple segments from upstream chip design to memory and semiconductor materials. On January 27, Zhaoyi Microelectronics issued a price adjustment notice, announcing increases of 15% to 50% for products including MCUs and Nor Flash, effective immediately. The very next day, January 28, the company's stock price surged 19.47%. On January 30, the stock price continued its ascent, rising over 13% at one point.
Earnings momentum. Statistics from 88 semiconductor industry chain companies that have released their 2025 earnings forecasts show that 59 have a positive upper limit for their projected growth, accounting for nearly 70%, with many stocks expecting doubled growth. The primary factors for earnings growth are highly correlated with increased market demand and price hikes. Several of these strong performers are precisely the stocks whose prices have accelerated recently; for instance, the stock price of Lanci Technology, which forecasts a maximum earnings increase of 66.46%, surged nearly 15% on January 30.
Furthermore, support comes from other typical events, such as the "National Team" stepping in to increase investment in semiconductor industry chain companies. Qichacha APP data shows that Anhui Juhe Microelectronics underwent a business registration change, adding new shareholders including Huaxin Dingxin (Beijing) Equity Investment Fund, affiliated with the third phase of the National Integrated Circuit Industry Investment Fund. The company's registered capital increased from 1.8 billion yuan to 5 billion yuan.
Bian Huizong, a familiar analyst to many, has conducted long-term, in-depth tracking and research on CPO, optical communication, and memory chips, and has repeatedly anticipated inflection points and initiation points for these sectors and individual stocks. Several key research cases from his "Learning by Doing" column subsequently developed strong price trends, such as the aforementioned Yangtze Optical Fibre And Cable Joint Stock Limited Company, which was featured on May 28, 2025, and December 10, 2025, and Puya Semiconductor, featured on December 18, 2025.
Whether it's Yangtze Optical Fibre And Cable Joint Stock Limited Company or Puya Semiconductor, both companies' stock prices initiated their rallies from relatively low levels before embarking on their strong upward trends.
CPO concept stocks are reporting a concentrated wave of positive earnings forecasts, with Yuanjie Semiconductor Technology Co.,Ltd. projecting growth exceeding 30-fold.
On January 30, the CPO sector rebounded after touching intraday lows, surging nearly 3% during the session and closing among the top three gainers out of over 260 concept sectors. Behind the robust rise of CPO, earnings realization served as a key catalyst.
Statistics from over 60 CPO concept stocks that have released 2025 earnings forecasts show that 51 have a positive upper limit for projected growth, accounting for over 80%. Companies like Yuanjie Semiconductor Technology Co.,Ltd., Huafeng Technology, Saige Electronics, Henan Shijia Photons Technology Co.,Ltd., and Changxin Bochuang all have projected growth上限 exceeding 4 times. Yuanjie Semiconductor Technology Co.,Ltd. forecasts an upper earnings limit of 205 million yuan, representing a staggering growth rate of 34 times. The company attributed the projected growth to factors including expansion in its data center business.
On the day following its earnings forecast release (January 30), Yuanjie Semiconductor Technology Co.,Ltd.'s stock price rose over 6%. As a standout performer spanning the year-end transition, the stock has accumulated an 8-fold increase since its low on April 8, 2025, directly linked to its better-than-expected earnings growth.
Additionally, several other stocks, including Henan Shijia Photons Technology Co.,Ltd., Changxin Bochuang, and Tongfu Microelectronics, experienced strong price increases after releasing their 2025 earnings forecasts. For example, Henan Shijia Photons Technology Co.,Ltd. stated on January 27 that it expects to achieve a net profit attributable to shareholders of approximately 342 million yuan for 2025, a year-on-year increase of about 425.95%. The company's stock price recently established an upward inflection point, rising nearly 10% on January 30.
CPO technology, which integrates optical engines and switch chips on the same substrate to shorten electrical signal transmission distances and reduce power consumption, is core infrastructure supporting AI computing power. The batch earnings growth among CPO concept stocks is closely tied to the continuously increasing industrial demand driven by AI. Founder Technology forecasted a maximum earnings increase of 98.14% for 2025, attributing it to benefits from accelerating expansion into high-value-added business orders for AI servers, high-speed optical modules, and high-end switches.
