SHEIN IPO: A $27B Listing
After a $100B Peak

Just 3.2x oversubscribed:
the new-issue fever is over

Look first at the subscription numbers: SHEIN's public offer was fully covered, with HK$5.88 billion in margin financing and around 3.2x oversubscription. Compared with last month's Unitree frenzy — 9.78 million retail investors fighting over 19,414 lots, a hit rate of just 0.2% — Hong Kong retail is noticeably calmer this time. Not because SHEIN is unknown, but because the belief that "new listings always make money" has been knocked awake by a string of first-day breakages in the first half of the year.

First-day performance among H-share IPOs in H1 was polarised: some surged, some broke. LINGYI iTech fell 4.6% on day one; Anker was roughly flat. SHEIN's modest 3.2x oversubscription is exactly what a cooling market looks like.

From US$100B to US$27B:
the cost of bad timing

The story of SHEIN's shrinking valuation starts in 2022, when the company closed its last funding round at US$100 billion — one of the most valuable private companies on earth. It then planned a US listing, but ran into regulatory and political headwinds, weighed a London listing, and finally landed in Hong Kong — four years later, at a valuation of US$27 billion.

What happened in those four years? First, global e-commerce growth slowed and the fast-fashion runway no longer looked infinite. Second, rivals like Temu attacked with even lower prices, putting pressure on SHEIN's growth story. Third, tariff and regulatory risks on Chinese cross-border e-commerce escalated, forcing the company to shift a large part of its supply chain to Southeast Asia at higher cost. Each factor piled on top of the last, and the valuation investors were willing to pay slid from US$100 billion all the way to US$27 billion.

For Xu Yangtian, this is a lesson in timing: the company's fundamentals did not collapse overnight, but once the listing window closes, valuation can evaporate by 70%. Listing is not just about raising capital — it is about cashing in value at the right moment.

Is US$27 billion
expensive or cheap?

For retail investors, the real question is not "what was SHEIN worth before", but "is US$27 billion fair today". That has to be answered with data, not with the gut feeling that a big company must be fine.

SHEIN is a classic "high revenue, thin margin" e-commerce model: huge revenue, but net margins that are not high. For companies like this, the price-to-earnings (P/E) ratio is close to meaningless — profit is so thin that small swings send P/E wildly up and down. The right approach is the price-to-sales (P/S) ratio — market cap divided by annual revenue — then compare with peers such as Zara's parent Inditex, H&M, and Pinduoduo, owner of Temu.

The logic of P/S is simple: revenue is the most stable metric for an e-commerce company. If SHEIN's P/S is clearly higher than peers, the market has already priced in future growth; if it is close to or below peers, only then is there a margin of safety. You do not need a talking head to compute this — with FinKit's IPO valuation calculator, enter the revenue, issue price and share count from the prospectus, and you get the answer in minutes.

Warrants, options and short selling
from day one — expect more volatility

One more detail worth noting: the exchange announced that SHEIN will have derivative warrants, options and permitted short selling from its very first day of trading. That means the market can trade it with leverage and bearish tools immediately. With concentrated share supply and a full derivatives suite, first-day price swings will be bigger than the average new listing.

For investors without shares, chasing the first-day surge is the most dangerous move; for those with shares, set a target price and a stop before you enter. A first-day pop is essentially a short-term supply and demand imbalance — limited supply, hot money — and the premium narrows over time. Historical data shows first-day winners typically give back 20% to 50% within a month.

Don't chase the myth —
value it yourself

SHEIN's listing is a textbook case: the same company was worth US$100 billion four years ago and US$27 billion today. Valuation is never "what a company is worth" — it is "what the market is willing to pay at this moment". The only reliable way for retail investors to survive this game is to compute a fair value from the data yourself, then check whether the offer price leaves a margin of safety.

Use FinKit's IPO valuation calculator: enter the prospectus numbers and get the P/S ratio instantly, then compare with peers. Only when you know your own fair value do you have the right to decide whether to subscribe — or to chase.
