As we enter the second half of October, the Hong Kong stock market's story goes beyond Q3 earnings delivery and sector rotation—the primary market is also buzzing: IPO listing activities have clearly picked up, and the topic of "subscribing to new listings" is back at the center of investors' attention. For Hong Kong, a market driven by the twin engines of "financing and trading," the recovery in new share supply is not only a signal that its financing function is being restored, but often also portends marginal shifts in liquidity and risk appetite. This article examines the logic behind the current IPO heat from four dimensions: institutional context, capital structure, subscription strategy, and risk control.
Warming IPO Market: A Dual Resonance of Policy and Liquidity
Continued Release of Institutional Dividends
Over the past two years, Hong Kong's listing ecosystem has undergone a systematic overhaul. HKEX has successively introduced new rules such as the listing regime for Specialist Technology Companies (Chapter 18C), while continuously refining arrangements for biotech companies and dual primary listings, opening financing channels for hard-tech and innovative drug companies. On the mainland regulatory front, the policy orientation of supporting leading mainland industry players in listing in Hong Kong and deepening cross-border connectivity between the two capital markets has remained stable. This improvement in institutional supply, combined with the queueing effect created by the relatively cautious pace of A-share IPOs, has led an increasing number of companies to view Hong Kong as their preferred or parallel financing platform.
The A+H Listing Wave Becomes the Main Theme
Over the past year or so, a number of leading A-share companies have successively launched or completed "A+H" dual listings, covering sectors representative of new quality productive forces such as power batteries, innovative drugs, high-end equipment, and consumer brands. For issuers, listing in Hong Kong not only brings in international long-term capital and optimizes their shareholder structure, but also builds up "ammunition" for overseas expansion; for the Hong Kong market, A+H names mostly have solid fundamentals and considerable market capitalization, so their pricing and post-listing performance directly affect market confidence in the IPO cycle, while also driving a simultaneous upturn across the primary and secondary value chain, including sponsorship, underwriting, and grey market trading.
Observing the Capital Side: Three Forces Behind the Subscription Boom
The rebound in IPO subscription enthusiasm is essentially the combined result of three types of capital.
- Reallocation by international long-term capital. Expectations of a loosening global liquidity environment have risen, and with valuations of some dollar assets remaining elevated, the allocation value of Asia-Pacific markets is being re-examined. As the international pricing center for Chinese assets, Hong Kong has absorbed a substantial share of the returning capital, and the willingness of cornerstone and anchor investors to participate has increased markedly.
- An upgraded role for southbound capital. The pool of eligible Stock Connect stocks continues to expand, and quality new listings quickly enter the investable range after going public. Mainland capital has been upgraded from "IPO subscribers" to "relay capital after listing," making the linkage between primary and secondary markets smoother and reducing liquidity risk when new shares fall below their issue price.
- The amplification effect of short-term leveraged capital. When the wealth effect emerges, margin subscription multiples tend to climb rapidly. This type of capital is less stable, acting both as an accelerant of the frenzy and as an amplifier of sharp price swings in the early days after listing.
It is worth noting that there are structural differences between IPO subscriptions in Hong Kong and the A-share market: new share issuance is dominated by international placements, with public offerings accounting for a smaller share; retail allotment rates are dynamically linked to subscription multiples; "grey market" trading takes place before listing; and there are no daily price limits. Returns and risks are therefore more multidimensional—an effective subscription framework must be built on an independent judgment of the issuer's fundamentals, rather than simply copying A-share experience.
