How to Judge Whether a Hong Kong IPO Is Expensive or Cheap

The first rule is simple: don’t call an IPO cheap just because the offer price is low.

A company offering shares at HK$2 may have a huge number of shares after listing, which can give it a very large market capitalisation. Another company offering shares at HK$80 may have fewer shares and a smaller total market value. The per-share number by itself tells you very little.

Market capitalisation = share price × total number of shares

For IPOs, the market capitalisation is usually shown in the prospectus under sections such as Summary, Offer Statistics, or similar. HKEX listing documents normally disclose offer statistics such as the number of shares to be issued, offer price range, expected market capitalisation and other related figures.

In my experience, this is the first number regular investors like us should check. Once you know the IPO market cap, you can start asking whether that valuation makes sense.

The IPO market capitalisation tells you what the market is being asked to pay for the whole company at the offer price.

Say a company is listing at an implied market cap of HK$10 billion. That means investors are being asked to value the entire business at HK$10 billion. Now the real work starts. Is that HK$10 billion reasonable for what the company earns today and what it may become in the future?

To judge that, compare the market cap with revenue, net profit, cash flow, assets, growth rate, industry position and business risks. A company with small revenue, weak profit and slow growth may look stretched at a high valuation. A company with strong margins, reliable profit and a clear market position may deserve a premium.

But be careful with IPO stories. Every prospectus tries to present a growth angle. The question is whether the numbers back it up.

For companies already making money, the price-to-earnings ratio, or P/E ratio, is one of the easiest valuation tools to understand.

P/E ratio = market capitalisation ÷ net profit

If a company is valued at HK$10 billion and made HK$500 million net profit, the P/E ratio is 20 times. In plain English, investors are paying HK$20 for every HK$1 of annual profit.

A lower P/E can look cheaper, and a higher P/E can look more expensive. But don’t use it blindly. A company with fast, sustainable growth may deserve a higher P/E. A company with falling profit, weak cash flow or cyclical earnings may deserve a lower P/E.

For Hong Kong IPOs, I usually treat P/E as a starting point, not the final answer. It works best when the company is already profitable and the profit is not just a one-off good year before listing.

Some IPO companies don’t have profit yet. This is common in biotech, technology, internet, electric vehicle, advanced manufacturing and specialist technology sectors. For these companies, P/E may be meaningless because the earnings number is negative.

That’s where the price-to-sales ratio, or P/S ratio, can be useful.

P/S ratio = market capitalisation ÷ revenue

If a company is valued at HK$10 billion and has HK$2 billion of annual revenue, its P/S ratio is 5 times. That means investors are paying HK$5 for every HK$1 of revenue.

A high P/S ratio is not automatically crazy. Some companies really do grow quickly and later turn revenue into profit. But a high P/S becomes dangerous when revenue growth slows, margins stay poor, or the business keeps burning cash without a clear path to profit.

For pre-profit IPOs, I always ask: is this company genuinely scaling, or is it just selling a future dream? There’s a big difference.

A valuation number means very little by itself. A 20 times P/E can be cheap in one sector and expensive in another. That’s why peer comparison matters.

If you’re looking at a restaurant IPO, compare it with listed restaurant groups. If it’s a medical device company, compare it with listed medical device names. If it’s a SaaS or specialist technology company, compare it with companies that have similar business models, growth profiles and margins.

Peer comparison helps you ask practical questions: Is this IPO priced higher than similar listed companies? Is it growing faster? Are its margins better? Does it have stronger brand power, technology, patents or distribution? Does it really deserve a premium?

One warning: don’t force bad comparisons. A luxury brand shouldn’t be compared casually with a mass-market retailer. A clinical-stage biotech company shouldn’t be compared directly with a mature profitable pharmaceutical group. Wrong peers can make a valuation look cheaper than it really is.

A company asking for a high valuation needs a good reason. Usually, that reason is growth, margin, or both.

Revenue growth tells you whether the business is expanding. Profit margin tells you how much money the company actually keeps after paying costs. Two companies can both have HK$1 billion revenue, but they may be very different businesses. One may earn a 30% net margin, while the other only earns 3%. The first company may deserve a higher valuation because it turns sales into profit more efficiently.

Still, growth quality matters. If growth came mainly from one big customer, one temporary contract, heavy discounts, or a short-term trend, I’d be careful. IPO numbers often look best right before listing. You want to know whether the growth can continue after the bell-ringing ceremony is over.

Sometimes an IPO looks cheap for a reason. The risk factors section is where you may find that reason.

Common warning signs include customer concentration, supplier concentration, high debt, regulatory pressure, litigation, falling margins, weak operating cash flow, dependence on founders, or heavy competition. These are not just boring legal paragraphs. They can explain why a company is priced at a discount.

IFEC has warned that IPO investors can focus too much on potential return and overlook risk, and that even popular IPOs may fall below the offer price after listing. That’s not theory. Anyone who has applied for a few hot Hong Kong IPOs has probably seen this happen.

So if a company is ‘cheap’, ask why. Is the market missing something? Or is the business genuinely risky? Cheap is attractive only when the risk is understood and fairly priced.

The use of proceeds section tells you what the company plans to do with the IPO money. It’s worth reading because it shows management’s priorities.

If the proceeds are mainly going into expansion, new products, research and development, production capacity or technology investment, that may support future growth. If a large portion is used to repay debt, you should ask why the balance sheet needs repair. If the wording is vague, like general working capital, the plan may be less informative.

Debt repayment is not automatically bad. Sometimes cleaning up the balance sheet is sensible. But as an IPO investor, you want to know whether your money is funding growth, survival, restructuring, or simply giving earlier stakeholders a way out.

This is where many small players get caught. A hot public offer does not automatically mean an IPO is fairly valued. It may simply mean the market is excited, liquidity is strong, or people are chasing first-day gains.

Hong Kong IPOs normally have a public offer for regular investors and an international placing for institutional investors. A heavily oversubscribed public offer may trigger more public allocation under the applicable clawback mechanism. Under the current HKEX framework, some IPOs may use Mechanism A, where the public tranche starts at 5% and can increase to 15%, 25% or 35% depending on demand. Others may use Mechanism B, with at least 10% initially allocated to the public tranche and no clawback.

This matters for allotment, not valuation. More demand may improve sentiment, but it doesn’t make an expensive company cheap. Before you subscribe, separate the two questions: How likely am I to get shares? And are those shares worth the IPO price?

Even a reasonably priced IPO can struggle in a weak market. If the Hang Seng is soft, liquidity is tight, or the sector is out of favour, investors may avoid new listings. Growth companies can also suffer when interest rates are high because future earnings are discounted more harshly.

On the other hand, when the market is hot and the sector is fashionable, IPO valuations can stretch quickly. That may help short-term performance, but it also increases the risk of overpaying.

In other words, valuation is not just accounting. It’s also timing, demand and confidence. But market mood should support your analysis, not replace it.

Before deciding whether a Hong Kong IPO is expensive or cheap, I’d run through these questions:

• What is the IPO market capitalisation?
• Is the company profitable?
• If profitable, what is the P/E ratio?
• If loss-making, what is the P/S ratio?
• How fast is revenue growing?
• Are margins improving or getting worse?
• How does the valuation compare with listed peers?
• What are the biggest risk factors?
• How will the IPO proceeds be used?
• After considering the risks, does the valuation still make sense?

If you can’t answer most of these, you probably don’t understand the IPO well enough yet. And that’s fine. Missing one IPO is not a disaster. Paying too much for a story you don’t understand is the real problem.

To judge whether a Hong Kong IPO is expensive or cheap, don’t stop at the offer price. Look at market capitalisation, profit, revenue, growth, margins, peer valuation, use of proceeds and risks.

A low share price doesn’t automatically mean cheap. A high share price doesn’t automatically mean expensive. What matters is whether the IPO price is fair for the company’s current business and future growth.

In my experience, the best question is not ‘Is the share price low?’ It’s: ‘Am I paying a sensible price for this company, after understanding both the upside and the risk?’ If the answer is still fuzzy, wait. The market always gives you another IPO to look at.
