Hong Kong is approaching a significant test in its equity markets as shares worth US$274 billion from recent IPOs face lock-up expiration over the next year. This influx of supply could pressure stock prices but also offers opportunities for discerning investors focusing on strong revenue growth and market liquidity.
- US$274 billion worth of shares locked post-IPO expected to enter market in next 12 months
- Stocks with strong revenue growth and solid cornerstone ownership offer better resilience
- Hong Kong’s IPO market leads globally, attracting $13.3 billion in Q1 2026
What happened
Hong Kong is experiencing a historic wave of lock-up expiry linked to a record volume of IPOs over the past year. Shares worth US$274 billion are potentially becoming eligible for trading as typical six-month lock-up restrictions come to an end. This release will feature stocks from some of the city’s standout IPOs, including MiniMax Group and Knowledge Atlas Technology, signaling a dramatic increase in market supply.
The city’s IPO market recently surged, reclaiming the top global ranking with US$13.3 billion in share sales during the first quarter of 2026. Overall, new share offerings last year totaled US$37.2 billion, driven by large mainland companies listing in Hong Kong and global investors seeking diversification away from the US.
Why it matters
The expiration of lock-up periods introduces a supply overhang that could depress share prices, as historical data from Goldman Sachs shows stocks typically experience a median 4% decline three months post lock-up expiry, worsening to 7% after six months. This dynamic adds further uncertainty to Hong Kong equities, which have underperformed global peers partly due to limited exposure to hot themes like artificial intelligence.
Market participants warn that stocks with large post-IPO share releases, especially those with notable initial gains, are vulnerable to technical selling pressure absent new buying liquidity. Investors are advised to prioritize companies with annual revenue growth surpassing 20%, cornerstone ownership between 30% and 50%, and market valuations above HK$5 billion, which benefit from greater retail and mainland investor participation via channels like Stock Connect.
What to watch next
Investors should closely monitor supply dynamics tied to lock-up expiries alongside demand drivers such as mainland China investor flows and retail interest, which together could generate over US$400 billion in buying power. This demand may help offset the increased share supply and stabilize prices, especially for IPOs meeting growth and liquidity thresholds.
Key stocks like AI developer MiniMax, semiconductor firm Iluvatar CoreX, and consumer company Busy Ming are cited as potential outperformers due to strong revenue growth, moderate cornerstone ownership, and robust retail oversubscription. Market watchers will also track developments around index inclusions and enhancements in cross-border trading access, which could deepen liquidity pools and transform the IPO supply surge from a short-term technical concern into a sustained investment opportunity.
