Zhongju Xuchuang HK Stock Debuts Below Issue Price: Valuation Game of Trillion-Dollar AI Computing Power Leader
Keywords: Zhongju Xuchuang, HK IPO, Below Issue Price, AH Share Premium, AI Computing Power, Optical Module, Valuation Convergence
On July 30, 2026, Zhongju Xuchuang (03308.HK), the absolute leader in the global optical module sector, officially listed on the main board of the Hong Kong Stock Exchange, completing its strategic placement on the "A+H" dual capital platform. As the first trillion-market-cap A-share company to achieve dual-listing this year and the largest IPO in terms of fundraising in the HK market since 2026, Zhongju Xuchuang's debut was highly anticipated by global capital. However, the market did not welcome this newcomer with enthusiasm, as it opened below its issue price, launching a complex game of valuation, sentiment, and fundamentals.
First-Day Below Issue Price: Luxury Cornerstone Investors Cannot Overcome Market Sentiment
In this global offering of Zhongju Xuchuang H-shares, the final pricing was locked at HK$980 per share, slightly below the upper limit of the offering range, showing the company's prudent attitude toward pricing. Its basic offering was 54.5 million shares, raising approximately HK$53.41 billion; if the 15% over-allotment option is fully exercised, the total fundraising could reach up to HK$61.422 billion, topping the HK new stock fundraising chart for 2026 and setting a record for the largest new stock fundraising in HK in nearly seven years since Alibaba's secondary listing in 2019.
However, the market did not show enough tolerance for this glory. At the HKEX opening, Zhongju Xuchuang quoted HK$971, down 0.92% from the issue price, signaling it was trading below issue price. Calculated based on the trading unit of 50 shares per lot, investors who entered at opening immediately faced an unrealized loss of HK$450 (excluding transaction fees). Trading data shows that after the market opened, trading activity quickly became active, with morning trading volume continuously expanding, as both bulls and bears engaged in fierce confrontation.
In fact, weak market sentiment had already emerged during the pre-market trading session the day before listing. In pre-market trading, Zhongju Xuchuang fell to a low of HK$931, with a maximum decline of nearly 5%, and finally closed at HK$969.5, down 1.07% from the issue price, releasing adjustment pressure in advance. Even though the cornerstone investor lineup for this IPO was堪称豪华, including 33 top institutions such as Temasek, Abu Dhabi Investment Authority, BlackRock, Hillhouse, Tencent, and Alibaba, with cornerstone subscriptions accounting for nearly 50%, and the Hong Kong public offering was oversubscribed by 16.84 times, these positive signals ultimately failed to stop profit-taking by short-term funds and market pessimism.
 The chart shows that Zhongju Xuchuang HK stock opened below issue price on its first day, with share prices continuing to decline, with a maximum drop of nearly 5%, reflecting short-term market divergence and valuation pressure.
AH Dual Pressure: Valuation Convergence and Arbitrage Game
The first-day share price pressure was the result of multiple factors. First, from the perspective of the macro market environment, the global AI computing power industry chain has recently entered a valuation digestion phase. Increased volatility in overseas tech stocks has significantly heightened market分歧 about the short-term prosperity of the optical module industry, bringing industry-level pressure to Zhongju Xuchuang as the "shovel seller" of AI computing power.
Second, the valuation gap between A-shares and H-shares has become a key variable affecting the stock price. For a long time, the A-share market has given higher valuation premiums to technology growth stocks, while the HK market tends to be more rational and international. Zhongju Xuchuang A-shares (300308.SZ) had already accumulated significant gains and valuation before listing. This HK listing is widely expected to quickly narrow the AH share premium rate.
This expectation triggered a chain reaction in the A-share market. Linked to the below-issue-price performance in HK, Zhongju Xuchuang A-shares fell sharply today. Before the deadline, A-shares closed at RMB 879.00, a drop of 7.57%, with total market capitalization falling to RMB 1.03 trillion. Previously, although the company announced a maximum RMB 8 billion share buyback plan on July 28 and clarified rumors about 1.6T optical module prices, A-shares briefly rebounded 4.74% to RMB 951 on July 29. However, the expectation of a below-issue-price debut on the HK market, combined with clear AH valuation arbitrage space, led to accelerated capital outflow from A-shares. At today's exchange rate, RMB 879.00 corresponds to approximately HK$1,019, while the H-share opening price was HK$971, with the AH premium rate quickly shrinking to only about 5%, significantly narrower than before, revealing clear valuation convergence pressure.
In addition, the entry threshold for this HK listing was as high as nearly HK$49,000 (50 shares per lot), and the relatively high participation threshold also limited the承接能力 of retail funds to some extent, constraining upward market momentum.
Strong Fundamentals: Structural Support Under AI Dividends
Despite the poor short-term stock performance, Zhongju Xuchuang's fundamentals remain strong, which is the core of its long-term value. As the absolute leader in global high-speed optical interconnection, the company has ranked first in global optical module market share for five consecutive years, deeply benefiting from the wave of global AI computing power construction. According to reference data, in 2025, the company achieved revenue of RMB 38.24 billion, a year-on-year increase of 60.25%, with net profit exceeding the 100 billion mark; entering 2026, first-quarter performance continued to grow rapidly, with quarterly net profit already surpassing the first half of last year. These data strongly prove its core position and profitability in the high-growth cycle of AI computing power.
The company has clearly stated that the funds raised from this HK listing will focus on investing in cutting-edge technologies, including 3.2T optical modules, silicon photonics, CPO (co-packaged optics), etc., aiming to continuously expand high-end production capacity, improve upstream and downstream industry chain layout, and consolidate its global competitive advantage. This indicates that the company is not just raising funds, but making long-term technological layouts and deepening its global strategy.
Outlook: Technology Iteration and Capital Layout
Industry analysts generally believe that this dual "A+H" layout is a key step in the company's internationalization strategy. Listing on HK helps the company further connect with global long-term capital, broaden international financing channels, and better match the business layout of its overseas customers, enhancing its global influence.
In the short term, Zhongju Xuchuang's stock performance will still be affected by market sentiment, sector rotation, and macro environment. As of the deadline, its HK stock price is still falling further, with the loss expanding to 4.69%, trading at HK$934 per share, with a maximum intraday decline of nearly 5% to around HK$931. However, from a medium-to-long-term perspective, the fundamental support for the company's value still lies in the pace of capital expenditure by global cloud providers, the iteration progress of high-speed optical module products, and the industry's competitive landscape.
Many institutional analysts point out that the optical module industry has fast technology iteration cycles, industry growth highly depends on AI computing power capital expenditure, and there are also potential risks such as high customer concentration and geopolitical changes. With the gradual implementation and large-scale commercialization of next-generation high-speed products such as 3.2T, silicon photonics, and CPO, Zhongju Xuchuang's future performance realization ability will become the most important cornerstone of its valuation system. This HK below-issue-price debut may be a cruel but necessary stress test for the market, testing investors' belief in the company's long-term value and its ability to continue leading in the technology wave.
