SK Hynix was reported to be in talks to buy Intel's unfinished Ohio chip campus. Hours later, SK Hynix formally denied the report in a Korea Exchange filing.
Kosdaq's trading value hit an 11-month low. Kospi's rally on record chip exports didn't change that.

Korea's top ETF manager sells leveraged Samsung and SK Hynix funds for a living. This week, he told investors to stop buying them. (July 21, 2026)
Bae Jae-kyu, the CEO known as the father of Korea's ETF market, posted on Facebook that investors should stop buying single-stock leverage ETFs, then deleted it. His own firm sells the exact products, and the same day, lawmakers held a forum on a market where the sell sidecar has triggered 38 times this year.
Kospi's 3.56% rise triggered a buy-side sidecar. Korea's chip exports just surged 180%.
Kospi closed up 3.56% Tuesday and briefly triggered a buy-side sidecar, but the real driver was a 180.6% rise in Korea's semiconductor exports, not a fresh JPMorgan call. That call is nearly a month old, and it landed in the middle of a rough stretch for Samsung's foreign ownership specifically.
Kospi's one-month drop is the worst of 46 major economies. Even Russia did better. (July 20, 2026)
Kospi fell 28.02% in one month, the worst return among 46 major economies tracked, even below Russia's own sanctions-driven slide. It is still up 54.63% since the end of last year, but analysts say leverage and semiconductor concentration made the drop worse than plain profit-taking.
SK Hynix in Korea moved from down 5.8% to up 2.7% to down 4.2%. Here is why a leveraged bet on that day would have hurt even more
SK Hynix's Korea-listed shares and the Kospi moved through a huge range and still closed down more than 4% on Monday. Here is the math on why a 2x leveraged position on a day like that is more dangerous than it looks, even after a partial recovery.

About 307 companies on Korea's Kosdaq exchange, close to 17% of the board, are sitting below the price or size thresholds that can lead to delisting, some with as little as a month left to fix it.

SK Hynix's (SKHY) 'reverse kimchi premium': Americans now pay 25% more than Seoul for the same stock
SK Hynix's US shares (SKHY) closed Friday at $154.03, about 25% above the same company's price in Seoul. Korean media calls it the reverse kimchi premium. The difference reached 51% on July 14, and analysts say a premium this wide usually starts pulling the cheaper Seoul shares upward.

Boston biotech Ingenia Therapeutics is about to become the first foreign company to list on the Kosdaq in five years, with three more Korean-founded US biotechs lining up behind it. Korea's regulator says a NYSE-listed company has directly inquired too, ahead of a September investor roadshow.
Broadcom just picked its next supplier, and it is not Samsung Electronics or SK Hynix.
Samsung Electro-Mechanics and LG Innotek, not Samsung Electronics or SK Hynix, are racing to supply Broadcom with the substrates its AI chips sit on. One has already won Broadcom's business and is shipping glass substrate samples. The other is fielding trillion won investment offers to catch up.
SK Hynix's own chairman had one message for panicking investors: stop trading, just hold. (July 17, 2026)
SK Group chairman Chey Tae-won told investors Friday to stop trading SK Hynix and just hold it, a day after the stock fell 11.5% in Seoul and its Nasdaq shares (SKHY) dropped another 13.7% overnight. By Friday afternoon, SKHY was already green, up more than 5% in New York trading.
Korea triples the deposit to trade its riskiest leverage ETFs. FSS chief Lee Chan-jin wishes he had stopped them sooner.
Korea's regulators tripled the minimum cash deposit for single-stock leverage products on Samsung and SK Hynix and halted new listings, after the products drove 16 of this year's 37 Kospi trading halts since their May launch. The financial regulator's own chief already said in June he wishes he had stopped them before they launched.
Korea-listed Samsung and SK Hynix ETFs are built to sell when the market drops. That is why the Kospi keeps crashing at the close.
A 2x leveraged ETF is designed to sell more every time its stock falls, and it does this near the market close. When the stock is Samsung or SK Hynix, each of which is a huge share of the Kospi, that automatic selling drags down the whole index. Here is how single-stock leverage ETFs have been quietly amplifying Korea's crashes.
Korea's president called the stock market unstable. Two days later, the Kospi crashed again (July 16, 2026)
South Korea's Kospi fell another 6.37% Thursday on a surprise Bank of Korea rate hike, two days after President Lee Jae-myung called the market unstable and blamed leveraged ETFs tracking Samsung and SK Hynix. The same week, regulators rolled out a new debt hotline after more than 320,000 accounts were forcibly liquidated this month.
SK Hynix's new Nasdaq stock rose 20% today. The same company in Seoul only gained 4%.
SK Hynix's week-old Nasdaq stock, SKHY, rose about 21% Tuesday. The company's original Seoul shares gained less than 4% the same day. The difference comes down to a very new, very thinly available ADR, and it is worth understanding before it happens with the next Korean listing.
A day after the crash, Kospi moved 3% in 15 minutes and Samsung opened green (July 14, 2026)
The Kospi opened Tuesday down 2.8% within ten minutes, then bounced nearly all the way back, a move of more than 3% before 9:15am in Seoul. Samsung opened green a day after the circuit-breaker crash, and the US CPI report lands six hours after the Korean close.
Why KOSPI moves so violently: two chip stocks, half the market, and 10x leverage
Samsung and SK Hynix are now nearly half of KOSPI, single stocks can move 30% in a day, and Korean retail investors trade with leverage tools that go up to 10 times their money. Here is how those three things combine into one of the world's most violent stock markets.
