I started subscribing to Hong Kong IPOs last August with HKD 50,000 in a brokerage account and a spreadsheet. Eight months and 12 IPO applications later, I've made a net profit of about HKD 8,200 — roughly 16.4% return.
That sounds decent until you realize three of those twelve lost money, four broke roughly even, and all the profit came from just two deals.
How HK IPO Subscription Actually Works
For anyone unfamiliar with the mechanics: when a company lists on the Hong Kong Stock Exchange, retail investors can apply for shares at the IPO price during a subscription window (usually 4-5 business days). You put up cash or margin financing, get allocated some shares (or none), and then sell on listing day or hold.
The key concept is the "one-lot strategy" — you apply for the minimum lot size, usually 100-500 shares depending on the stock price. This maximizes your allocation probability because HK IPOs use a clawback mechanism that favors small retail applicants when demand is high.
One lot typically costs between HKD 2,000 and HKD 20,000 depending on the share price. Your capital is locked for roughly 5-7 business days from application to listing.
The Two That Paid for Everything
Huayan Intelligence (华燕智能, 2月上市): This was the robotics company that got something like 5,000x oversubscribed in the retail tranche. I applied for one lot (500 shares at HKD 10.28 each, so about HKD 5,140 committed). Got my one lot — the allocation rate was brutal but the one-lot guarantee kicked in.
It opened at HKD 18.60 on listing day. I sold at HKD 17.80 after it dipped from the open. Net profit after fees: roughly HKD 3,700.
A chipmaker IPO in November (I won't name it because I still hold a small position): Applied for one lot at HKD 42 per share, 200 shares. Listing price jumped to HKD 58. Sold half on day one, kept the rest. That half-sale netted about HKD 3,200.
Those two deals alone account for HKD 6,900 of my total HKD 8,200 profit.
The Losers
A biotech company in October: Classic mistake. Applied because the company had a cool pipeline, ignored that biotech IPOs in HK have a terrible track record for retail investors. It dropped 12% on listing day. I ate an HKD 800 loss on one lot and learned my lesson about sector patterns.
An EV component supplier in January: Priced at what seemed reasonable, but the grey market (暗盘) was already trading below IPO price the night before listing. I should have sold in the grey market when I saw that signal. Instead I held to listing, watched it open down 8%, and took about HKD 600 in losses.
A logistics tech company in December: Tiny loss, maybe HKD 200. Just a nothing IPO with no momentum.
What I Learned About Which IPOs to Apply For
After 12 attempts, my rough filter:
Apply when: Subscription multiple above 100x (check real-time subscription data from brokers), company is in AI/robotics/chips (the market has a clear appetite), sponsor is a tier-1 bank (Goldman, Morgan Stanley, CICC), and the grey market price on 富途/moomoo the evening before listing is above IPO price.
Skip when: Biotech pre-revenue, subscription under 20x, mainland property developers (the market is done with these), or when more than 3 IPOs are listing in the same week (capital gets diluted).
The grey market signal is probably the single most useful indicator. If 暗盘 is trading below IPO price, you're almost certainly going to lose money on listing day. I now check this religiously and have avoided two bad deals because of it.
The Capital Lock-Up Problem Nobody Talks About
Here's the thing that bothered me most. When you apply for a hot IPO, your capital — or your margin limit — is locked for nearly a week. During that time, you can't use that money for anything else.
For my HKD 50,000 account, applying for 2-3 IPOs in the same period could tie up 60-80% of my capital. There were weeks in Q1 where Hong Kong had 4-5 IPOs launching simultaneously and I had to pick which ones to allocate to.
The opportunity cost is real. That HKD 50,000 sitting in a savings account would earn maybe HKD 150/month in interest. If my capital is locked in IPO applications 40% of the time and I'm picking wrong half the time... the math gets questionable fast.
Q1 2026: Hong Kong's Moment
To be fair, this has been an unusually good period for HK IPOs. The exchange raised over HKD 300 billion in Q1 alone, briefly overtaking both NYSE and Nasdaq for global IPO volume. The pipeline is packed with Chinese tech and AI companies that either can't or won't list in the US due to regulatory uncertainty.
That tailwind won't last forever. The subscription multiples I'm seeing now — 500x, 1000x, even 5000x for Huayan — are not normal. A year ago, most HK IPOs were struggling to get 10x subscribed.
I'm adjusting my expectations downward for the rest of the year.
Broker Comparison: Moomoo vs IBKR
I use moomoo (富途) as my primary IPO broker and IBKR as backup. Quick comparison:
Moomoo: Better for HK IPOs specifically. Real-time subscription data, grey market trading access, 0 commission on IPO shares sold within 30 days (they run this promo frequently), and the interface is designed around the HK retail investor experience. IPO margin financing at about 3.8% annualized. The app is in Chinese, which is fine for me but might not work for everyone.
IBKR: More IPO markets (US, EU, HK, Singapore), but the HK IPO experience is clunky. No grey market access, subscription data is delayed, and the application process has more steps. Lower margin rates overall, but for the 5-7 day IPO lock-up period, the rate difference is negligible.
If you're only doing HK IPOs, moomoo wins. If you want flexibility across multiple markets, IBKR is the safer long-term choice.
The Spreadsheet Tells the Truth
Here's my 8-month summary:
| Metric | Value |
|---|---|
| Total applications | 12 |
| Allocated | 10 (83%) |
| Profitable on listing day | 5 |
| Loss on listing day | 3 |
| Roughly break-even | 4 |
| Net profit | ~HKD 8,200 |
| Capital deployed | HKD 50,000 |
| Return | ~16.4% (8 months) |
| Annualized | ~24.6% |
That 24.6% annualized looks great on paper. But it requires active monitoring (I check subscription data daily during IPO windows), occasional grey market trades at odd hours, and the emotional discipline to skip deals when the signals aren't there.
Most months I spent about 3-4 hours total on research and execution. Not passive income by any stretch.
Would I Recommend It?
With caveats.
If you have idle capital in a HK brokerage account anyway — money that's just sitting in a settlement account earning nothing — then applying for high-conviction IPOs with the one-lot strategy is a reasonable use of that capital. The downside per application is small (you lose a few hundred HKD if it drops 5-10% and you sell immediately), and the upside on a hot deal can be meaningful.
If you'd need to wire money specifically for IPO subscriptions, the friction and fees probably aren't worth it unless you're committing at least HKD 100,000+.
And if you're expecting consistent returns — don't. My 16.4% came from exactly two good deals out of twelve. That's not a strategy, that's a sample size problem. Ask me again after 50 applications and I'll have more confidence in whether this actually works long-term or whether I just got lucky during a bull window.
The honest answer is probably somewhere in between.
