Recently, the STAR Market has continued to recover. Since April 1, the STAR 50 Index has risen by 15.71%. During this period, a total of 47 individual stocks on the STAR Market hit new historical highs.

After analyzing 11 companies with a total market capitalization exceeding 50 billion yuan, it was found that the AI computing hardware sector accounts for the vast majority of this list, including companies such as Biwin Storage, Yuanjie Technology, Shengke Communication, Everlight Electronics, Huafeng Technology, Shijia Photonics, and Qiangyi Stock. Among these, except for Biwin Storage and Qiangyi Stock, the remaining stocks belong to the optical communication sector.

In terms of interval gains, the optical communication sector also holds a relatively leading position. Among them, Everlight Electronics and Shijia Photonics are particularly notable, with cumulative gains of 87.25% and 72.50%, respectively.

The computing hardware track, centered on optical communication, was the main line with the highest consensus among funds in early April. Moreover, the profit-making effect is no longer limited to the CPO concept, but has spread across the entire industry chain, including sub-sectors such as OCS, PCB, optical fiber, and optical chips. Additionally, there is a trend of rotation from high to low within computing hardware, with stocks like Changxin Bochuang, Guangxun Technology, and Shijia Photonics, which were previously at relatively low positions or had fully adjusted, showing sharper gains.

The concentrated influx of funds into the “optical” sector is not coincidental. As of press time, some of the aforementioned optical communication concept stocks have disclosed their first-quarter reports for 2026, with many showing excellent performance. For example, Everlight Electronics achieved operating revenue of 130 million yuan, a year-on-year increase of 37.81%; net profit attributable to shareholders of the listed company was 4.4796 million yuan, turning losses into profits year-on-year.

This performance growth may stem from the explosion in demand for optical communication. In its first-quarter report, Shijia Photonics mentioned that the market demand related to artificial intelligence has increased, the company’s production and operation capabilities have improved, and product sales orders have increased. Everlight Electronics stated that it adheres to a horizontal expansion strategy, and the revenue growth in the first quarter mainly came from the growth of previously deployed optical communication businesses.

Outside the STAR Market, the optical communication leader Zhongji Innolight exceeded expectations in its first-quarter report. The company achieved a net profit attributable to the parent company of 5.7 billion yuan, a year-on-year and quarter-on-quarter increase of 262% and 56%, respectively. The performance change is mainly due to the strong investment by end customers in computing infrastructure, leading to continued growth in product shipments. In its latest report, it was stated that as data center architecture evolves from horizontal to vertical, it brings higher bandwidth and more connection needs, significantly driving the expansion of the overall serviceable market.

From the perspective of overseas mapping, Lumentum’s demand for optical components from U.S. hyperscale data center customers is accelerating, and orders are already fully booked through 2028. Meanwhile, Applied Optoelectronics stated in a conference call that it aims to achieve monthly production capacity of over 500,000 units of 800G and 1.6T by the end of 2026, while also planning to more than triple its optical chip production capacity in Texas, reflecting the urgent and continuously overflowing “additional order” demands from downstream customers.

In a research report on April 22, it was indicated that as the market gradually becomes desensitized to the turbulence in the Middle East, optical communication has become the track with the highest certainty of benefiting from this round of AI investment explosion and has vast long-term space, potentially showing significant excess returns over the broader market. In addition to leading optical module stocks that are consistently delivering performance, funds are expected to spill over more to “small optical” targets from individual stock position considerations.

Commercial Aerospace and Innovative Drugs Emerge

From the above list, it can be seen that besides companies “standing in the light,” some commercial aerospace and innovative drug concept stocks are also favored by funds. For example, Raytron Technology has laid out both satellite payloads and ground terminals. The company stated that it will actively explore more application areas and strive to continue growing by riding the wave of commercial aerospace.

It is worth noting that the commercial

STAR Market

The STAR Market, officially known as the Science and Technology Innovation Board, is a stock exchange segment launched in Shanghai in 2019 to support high-tech and innovative companies, particularly in sectors like biotech and AI. It was created as part of China’s broader effort to modernize its capital markets and reduce reliance on foreign exchanges for tech listings. With more flexible listing rules, it has quickly become a key platform for emerging Chinese enterprises to raise capital.

STAR 50 Index

The STAR 50 Index is a stock market index that tracks the performance of the 50 largest and most liquid companies listed on the Shenzhen Stock Exchange’s ChiNext board in China. Launched in 2020, it focuses on high-growth, innovative firms in sectors like technology, healthcare, and new energy. The index reflects China’s push to support emerging industries and provide investors with a benchmark for the country’s dynamic startup ecosystem.

optical communication sector

The “optical communication sector” is not a single physical place but a broad field of technology and industry focused on transmitting information using light, typically through fiber-optic cables. Its modern history began in the 1960s with the invention of the laser and the development of low-loss optical fibers, which revolutionized global telecommunications. Today, this sector underpins the internet and high-speed data networks, enabling rapid, long-distance communication that connects the world.

CPO concept

The CPO concept, or Central Post Office, often refers to historic postal buildings in major cities, such as the iconic CPO in Kuala Lumpur, Malaysia. Built in the early 20th century, it originally served as the city’s main postal hub and later transformed into a cultural and commercial landmark. Today, it represents a blend of colonial-era architecture and modern urban development, symbolizing the evolution of communication and commerce.

OCS

The OCS, or Officers’ Christian Union, is a UK-based organization that supports Christian officers in the British Armed Forces. It was founded in 1852 as the “Naval and Military Bible Society” and later renamed, providing spiritual guidance, fellowship, and resources to military personnel. The group emphasizes leadership development and ethical decision-making within a Christian framework.

PCB

PCB stands for the Pile Church in Baku, Azerbaijan, a historic Zoroastrian fire temple built in the 17th–18th centuries. Located in the Surakhani district, it was constructed over a natural gas vent that produced an eternal flame, central to Zoroastrian worship. The site later became a place of pilgrimage for Hindus, Sikhs, and other fire-worshipping communities, and today it operates as a museum showcasing its religious and cultural history.

optical fiber

Optical fiber is a technology that transmits information as light pulses through thin, flexible strands of glass or plastic. Its history began in the 1840s with early light-guiding experiments, but the modern concept was pioneered in the 1960s by Charles K. Kao, who demonstrated that purified glass could carry light over long distances, earning him a Nobel Prize. Today, optical fibers form the backbone of global telecommunications, enabling high-speed internet and data transfer.

Texas

Texas is a large and culturally diverse state in the southern United States, known for its distinct identity shaped by its history as an independent republic from 1836 to 1845. Originally inhabited by Native American tribes, it was colonized by Spain and later Mexico before Anglo-American settlers led a successful revolution, resulting in the iconic Battle of the Alamo in 1836. Today, Texas is famous for its cowboy culture, oil industry, and vibrant mix of Mexican-American heritage.
