February Sci-Tech Innovation Board Leading Stocks Scan: Semiconductors and Optical Communications Become Hotbeds for Bull Stocks, Multiple Companies Hit Record Highs

From February to the present (February 1 - February 18), which companies on the STAR Market have the top gains?

According to the “STAR Market Daily,” as of the time of publication, Hesin Instruments leads with a 49.59% increase, followed closely by Oulai New Materials and Juguang Technology, both with gains exceeding 40%. Among the top 10 gainers, many companies hold key positions within their specific industry chains, such as Juguang Technology and Jepte, which are riding the CPO wave, Oulai New Materials benefiting from the rising prices of target materials, and Sikan Technology collaborating with Tuozhu Technology.

Eight of the ten companies have hit new all-time highs this month, including Oulai New Materials, Juguang Technology, Microguide Nano, Nanya New Materials, Jepte, Xingtu Xinke, Sikan Technology, and Sains.

Looking at the reasons for the stock price increases, many companies have benefited from improved fundamentals, upstream price hikes, or new business developments.

Upstream raw material price increases

Oulai New Materials started construction on January 28 for its high-purity materials project for Mingyue Lake Semiconductor, with a total investment of about 108 million yuan. The project plans to build lines for high-purity oxygen-free copper ingots and high-purity cobalt ingots, expected to be completed and operational by Q4 of the same year. Northeast Securities states that Oulai New Materials has successfully entered the supply chains of global leading integrated circuit manufacturers such as SK Hynix and Yueya Semiconductor, demonstrating that its copper, aluminum, titanium, and other target materials meet international standards in purity and density. The Mingyue Lake project focuses on ultra-high purity 6N oxygen-free copper and high-purity cobalt ingots, aiming to solve the core raw material bottleneck in semiconductor target materials. Once operational, it will eliminate supply chain security risks and significantly boost profit margins. It is expected that by Q4 2026, the facility will have the capability to deliver entire production lines from raw materials to finished targets, shifting the semiconductor business from “sample verification” to “performance release,” becoming a second growth driver for the company.

Global prices for key materials in the semiconductor industry, such as sputtering targets made of aluminum, copper, high-end tantalum, and titanium, are generally expected to increase by 20%-30% in the first quarter of 2026.

Sains is developing molybdenum processing and rhenium recovery businesses. Its comprehensive rhenium resource recovery technology has been successfully industrialized at Duobao Mountain Copper, Zijin Heilongjiang, Zijin Jilin, and Luoyang Molybdenum. Zijin Mining holds a 21.11% stake in Sains. According to Dongwu Securities, since 2025, the price of high-grade ammonium perrhenate has increased by 139% (as of January 28, 2026), while rhenium has increased by 96%. The firm states that Sains, which controls core rhenium recovery resources, is well-positioned to benefit from rising rhenium prices and profit margins.

Strong demand for AI

The global wave of AI computing infrastructure construction is in full swing, with high demand for optical communications, computing power, and a super cycle in storage chips becoming consensus.

Microguide Nano is a leading domestic ALD equipment manufacturer, initiating R&D in semiconductor equipment in 2018. Its semiconductor business is rapidly growing; from Q1 to Q3 of 2025, the company signed new semiconductor orders totaling 1.483 billion yuan, a 97% year-over-year increase, indicating rapid development. Most orders come from top clients in NAND and DRAM sectors. Zhongtai Securities notes that, given the certainty of downstream storage line expansions and upgrades, the company’s exposure to these markets is large, and it is expected to benefit fully.

High-end CCL (copper-clad laminate) products driven by AI are continuously iterating. Nanya New Materials is the first domestic high-end CCL manufacturer with a full series of products certified by Huawei. Currently, M6-M8 products are mass-produced for leading domestic computing clients, while testing and validation for overseas high-end scenarios with M6-M9 Low CTE materials are accelerating. Western Securities states that supply-demand resonance is driving both volume and price increases for CCLs, with multiple product lines advancing simultaneously. On the supply side, since December 2025, mainstream manufacturers like Zhitang and Nanya have issued price adjustment notices, with weekly maximum price increases of 10%-20%, mirroring the limited supply characteristics seen in 2020. On the demand side, high-end application tracks show strong growth momentum.

Juguang Technology previously forecasted a net profit attributable to shareholders of -42 million to -32 million yuan for 2025, narrowing losses by 75.99%-81.70%. The narrowing loss is mainly due to a roughly 40% revenue increase and a higher proportion of high-margin products (such as optical communication micro-optical components). In Q3 2025, quarterly revenue reached 220 million yuan, up 50.12% year-over-year, with a net profit of 27.187 million yuan, and contract liabilities surged 843% to 57.47 million yuan, indicating high short-term revenue certainty.

In the optical communication sector, Jepte has launched products like MPO and FAU. MPO has obtained Senko system certification, MMC has passed USCON certification, and its subsidiary Matrix Optoelectronics’ FAU has been shipped in bulk to leading domestic optical module manufacturers. From Q1 to Q3 2025, the company’s revenue was 1.509 billion yuan, up 41.02% year-over-year, with a net profit of 204 million yuan, up 97.30%. In Q3 alone, revenue was 628 million yuan, up 31.90% year-over-year and 16.83% quarter-over-quarter, with a net profit of 109 million yuan, up 123.78% year-over-year and 83.53% quarter-over-quarter.

Emerging 3D printing targets

Sikan Technology is a leading domestic 3D scanner company. On January 29, it announced a framework cooperation agreement with Tuozhu Technology to jointly design and develop consumer-grade 3D scanners, with Sikan producing and selling to Tuozhu.

Tuozhu Technology is a leader in 3D printing. Founded only five years ago, it achieved over 10 billion yuan in revenue in 2025, capturing 29% of the global consumer 3D printing market share, becoming an invisible champion in the field. It is reported that Tuozhu’s year-end bonus payout in 2025 increased by over 50% compared to 2024. Among employee incentives, the maximum bonus amount and months are over 2 million yuan and 25 months, respectively.
