The first half of 2026 has presented a unique and contradictory picture in the Hong Kong stock market. While the major indices have shown weakness, the IPO market has experienced significant expansion and robust short-term performance for new listings.
Where to begin
Capital markets have long established a stable linkage where secondary market sentiment is highly synchronized with primary issuance activity. During periods of strong index performance, corporate willingness to list increases and fundraising scales expand. Conversely, when the broader market experiences sustained downturns, new listings commonly face pressure from discounted pricing and higher rates of falling below their issue price.
However, the first half of 2026 in Hong Kong has diverged from this pattern. The Hang Seng Index and Hang Seng Tech Index have largely maintained a corrective trend, with heavyweight stocks like Tencent, Alibaba, and Xiaomi showing persistent weakness. Despite this, the total funds raised through Hong Kong IPOs nearly doubled compared to the same period last year. Short-term returns for new listings were impressive, with the highest average first-day gain reaching 95% during the year, while the intraday rate of falling below the issue price continued to decline. This has created a noticeable decoupling between primary and secondary market trends.
Examining the current cycle
Reviewing the IPO fundraising cycles from 2021 to 2026 reveals that the Hong Kong primary market has typically followed a pro-cyclical pattern. The year 2021, when the Hang Seng Index was at a cyclical high, saw peak fundraising of HK$331.3 billion. As the secondary market declined from 2022 to 2023, fundraising contracted sharply to HK$104.6 billion and HK$46.3 billion, respectively, with many companies postponing listing plans. A slight recovery in 2024 did not lead to a significant rebound, with annual fundraising reaching only HK$88.1 billion. A sustained recovery in the Hang Seng Index from the second quarter of 2025 was accompanied by a significant rise in primary market fundraising, totaling HK$277.1 billion for the year, aligning with the traditional linkage logic.
The first half of 2026 became a special inflection point in this cycle. Despite the Hang Seng Index falling 10.7% in H1, underperforming most major global asset classes, and the secondary market remaining in a corrective phase, total IPO fundraising still reached HK$208.9 billion. This figure nearly doubled compared to H1 2025, creating a divergence from the secondary market trend.
This expansion in fundraising is supported by several objectively verifiable factors, forming the foundation for a reasonable market recovery. First, there has been a concentrated release of backlogged projects accumulated during the cyclical trough of 2022-2024. Second, tightening financing channels in the A-share market have spurred a wave of A+H listings, while the Hong Kong Exchange's institutional advantages have attracted a large number of high-quality unicorn companies. Third, a structural shift in industry sectors has elevated the average fundraising size per project, with hard technology companies in AI, chips, and computing hardware coming to market. Finally, a cohort of companies with solid fundamentals, including A+H dual-listed firms and leading hard-tech enterprises, has helped reshape and improve the overall structure of Hong Kong-listed companies.
Drivers of strong short-term IPO returns
Against the backdrop of a persistently weak Hang Seng Index, the first-day returns for Hong Kong IPOs have continued to strengthen, with performance completely detached from the broader market. The average first-day gain for new listings in Q2 2026 climbed to a cyclical high, while the intraday rate of falling below the issue price declined steadily from a peak of 67% in Q1 2025 to 23%. While the index weakened and heavyweight stocks corrected, first-day IPO returns rose and the rate of falling below issue price dropped significantly.
Data further reveals a core market characteristic: new listings generally experience concentrated buying pressure on their debut, but the sustainability of this momentum has a natural fracture. The phenomenon of exhausting price gains is far more pronounced among small and mid-cap listings compared to large, high-quality ones. Most small-cap stocks, even if they do not fall below their issue price in the medium to long term, see the floating profits realized on the first day shrink substantially over subsequent 10-day, 20-day, and 3-month periods, forming a fixed pattern of a "first-day spike followed by sustained weakness."
This differentiated performance cannot be simply attributed to short-term market sentiment. It stems from a multi-layered system of capital interplay that has evolved with market development. The implementation of the Stock Connect initially objectively improved secondary market liquidity for qualifying companies. Subsequently, market participants gradually explored the trading opportunities created by the rules, leading some small and mid-sized issuers to develop short-term market capitalization management objectives. The interplay between issuers, various capital sources, and sponsors has given rise to noteworthy market phenomena within the IPO process.
The evolution of the Stock Connect mechanism's benefits has been key. Initially, it provided a passive, benign improvement in liquidity for new listings. As the market deepened its understanding of the inclusion rules, this institutional benefit evolved from a "passive liquidity dividend" into an "actively replicable arbitrage path." Market participants realized that many small-cap new listings, whose original market capitalization did not meet the inclusion threshold, could quickly qualify for Stock Connect by artificially boosting their share price and market cap shortly after listing. Once included, the steady inflow of southbound capital would provide a stable exit channel for early investors and existing shareholders. The short-cycle, low-barrier inclusion rules from Hang Seng Indexes Company further reduced the time and operational costs for such activities.
In this context, some small and mid-sized issuers with short-term profit-taking motives began collaborating with capital to deliberately create momentum: concentrating efforts to boost the share price on the first trading day to precisely meet the Stock Connect inclusion criteria. Relying on market sentiment and southbound capital to provide liquidity, cornerstone investors, existing shareholders, and pre-positioned speculative capital could then exit, resulting in the fixed price pattern of a first-day spike followed by medium-to-long-term decline.
The differing operational objectives of companies have also played a role. Unlike large A+H enterprises focused on long-term capital market reputation, some smaller issuers view a successful listing as the primary goal. For them, the short-term gains from boosting market capitalization to open a Stock Connect exit window far outweigh the long-term returns from focusing on core business operations, making them willing to cooperate with speculative capital by tilting share allocations in their favor.
The expansion of online placement channels has introduced transparency concerns. While the private transfer of placement quotas existed before, it was previously confined to internal circles within brokerages and asset managers. The emergence of social media as a public platform for promoting placement quotas signals an overflow of demand for such channels and suggests that internal industry capital is no longer sufficient to absorb all placement quotas, necessitating the recruitment of external funds through public platforms.
Sponsors face a dilemma. The Hong Kong Exchange has continuously raised due diligence standards for investors in the placement process, requiring verification of fund sources and ultimate beneficial owners. In reality, some speculative funds cannot complete full verification, yet issuers rely on such capital as a core condition for listing success, pressuring sponsors to compromise. Sponsors are caught between the risk of regulatory penalties for allowing unverified funds and the risk of losing the project by refusing to cooperate.
A practical investment approach
The purpose of this analysis is not to advise investors to abandon participating in Hong Kong IPOs. The average first-day returns in H1 2026 were notable, and short-term participation still offers windows of profitable opportunity within the multi-party capital interplay. The key distinction lies in differentiating the risk levels of listings and locking in reasonable profit-taking ranges to avoid the medium-to-long-term valuation digestion risks associated with small-cap stocks.
Market listings can be clearly divided into two camps, corresponding to completely different trading strategies. A+H dual-listed companies benefit from the strict compliance reviews undergone during their A-share listing, resulting in more完善的 governance and信息披露 standards. Leading hard-tech companies in sectors like AI and computing possess solid financials and deep industry moats that provide fundamental support. Both types are primarily targeted by long-term industrial capital and foreign institutional investors, leaving limited room for short-term speculation and exhibiting controllable price volatility, making them suitable for stable, long-term allocation.
Small-cap new listings with limited issue size,明显 fluctuating performance, and reliance on narrative concepts fall into the speculative category. They offer充足 short-term upside potential but carry extremely high medium-to-long-term drawdown risks. They are suitable only for very small position sizes, with strict execution of profit-taking in the grey market or on the first day, avoiding long-term holdings to bet on further gains.
Investors can screen for high-risk targets during the offering stage using several criteria from公开 information. First, the absence of a sufficient greenshoe price stabilization mechanism. Second,基石 investor structures with明显 flaws, such as complete absence of基石 investors, very low基石 subscription ratios, or participation primarily by unknown institutions. Third, weak risk control within the sponsoring and underwriting team, indicated by an abnormally high number of承销商, dominance by small, unknown承销商, lack of a joint sponsorship by leading domestic and foreign firms, or a history of sponsor更换 on the project.
Long-term market outlook
Over a longer time horizon, the underlying logic of primary and secondary market联动 is unlikely to change fundamentally. The current arbitrage chain concentrated in small-cap stocks faces multiple压制 factors. The pace of southbound capital inflows is gradually slowing, reducing incremental承接 power. The continuous expansion of new listing supply throughout the year分流 short-term speculative capital. Listings from H1 2026 will face集中 selling pressure in the second half of the year as基石 and原始股东 lock-up periods expire. Simultaneously, the Hong Kong Exchange is持续 tightening穿透式核查 of placement funds, and regulatory constraints on operations like online兜售 of基石 shares or代持认购 are becoming stricter, compressing arbitrage空间.
In the long run, the core支撑 for Hong Kong IPO expansion remains the genuine industrial financing需求 from mainland hard-tech companies going global and A+H secondary listings. The market will continue to produce high-quality assets with long-term allocation value. Ordinary investors need not be干扰 by the speculative noise in small-cap stocks and completely abandon Hong Kong IPO participation. By剥离 the emotional filter created by short-term热度, distinguishing between short-term capital-driven momentum and genuine corporate growth logic, and avoiding the stock price下行 risks associated with the dual factors of "Stock Connect inclusion承接 +集中解禁," they can capture IPO红利 within a controlled range of volatility.
