Shein’s HK IPO sees retail rush but fails to hold offer price in first week

On the morning of August 27, the margin financing figures for Shein’s offering were still climbing, reaching HK$6.78 billion at one point, or 3.7 to 3.9 times the shares available. It was the last temperature check visible to the market during the subscription period. By the time the final allotment results were announced on the evening of August 31, the offering had been 5.63 times subscribed, with 35,751 valid applications and a ballot success rate of 18.42% for one-lot applications. Investors subscribing for 600 shares were guaranteed one lot. Retail investors were scrambling for what was Hong Kong’s biggest fashion IPO of 2026 to date.

But when trading began on September 1, the share price barely moved: it opened at HK$48.56 before sliding, briefly falling below HK$44 intraday and reaching a low of about HK$43.70 to HK$44.30, nearly 10% below the offer price. It recovered to HK$48.50 by the close, down just 0.12% from the offer price and barely at breakeven. The real answer emerged on the second and third trading days. Shein closed at HK$46.96 on September 2, down 3.18%, taking its market capitalisation below HK$200 billion. It fell another roughly 3% on September 3 to HK$44.60, extending its losses over two consecutive sessions to 8% and leaving it below the offer price.

The explanation for the retail enthusiasm lies not in demand, but in the supply structure. Shein offered 280 million Class B shares globally, while the Hong Kong public offering accounted for just 10%, or 27.9993 million shares. However enthusiastic retail investors might have been, the pool available to them was small from the outset. The international placing accounted for 90% of the offer and was 2.59 times subscribed, or 1.59 times oversubscribed, with just 106 placees, indicating a relatively concentrated allocation. More important was the cornerstone tranche. Seven investors — Boyu Capital, Tiger Global, General Atlantic, Tencent, Greenwoods Asset Management, Taikang Life Insurance and UBS Asset Management (Singapore) — subscribed for a combined approximately 61.9 million shares, representing about 22.1% of the global offering, and are subject to a six-month lock-up. When the shares fell to an intraday low of HK$43.72 on the listing day, the seven cornerstone investors faced combined paper losses of about HK$300 million. Boyu suffered the largest paper loss at about HK$117 million, followed by Tencent at about HK$39.11 million and Taikang Life at about HK$23.46 million. Funds accounting for nearly a quarter of the offered shares are locked up for six months and cannot be sold. They can neither cut their losses and exit nor provide near-term buying support.

In other words, the retail frenzy was concentrated in the 10% public tranche, while the freely tradable supply that actually determines the share price is far smaller than the market capitalisation of more than HK$200 billion might suggest. CICC Securities International previously noted that, based on net profit of US$2.064 billion in 2025, Shein’s implied price-to-earnings ratio at the offer price was about 12.4 to 12.9 times, below Inditex’s roughly 30 times and H&M’s approximately 22 times. That discount was not arbitrary: Shein’s prospectus showed that revenue in the first quarter of 2026 rose only about 1% year on year, while the company swung to a loss of about US$99 million. This was partly due to a fair-value loss of about US$328 million on convertible redeemable preference shares. The market was assigning Shein a valuation clearly below those of its peers while retail investors were still willing to queue up for the shares. In this stock, retail optimism and institutional pricing logic co-existed, but pushed in opposite directions.

Shein was added to the list of designated securities eligible for short selling on September 1, meaning the shares could be shorted from the first day of trading. Hang Seng Indexes Company also announced that Shein met the requirements for expedited inclusion and would be added to the Hang Seng Composite Index and its sector indexes after the market close on September 14, with effect from September 15. This means passive funds tracking the indexes will be required to build positions, providing one of the few known sources of buying demand with a clear timetable before the cornerstone investors’ six-month lock-up expires.
