Reported fundamentals
There is no stock score on this page. The score is computed from audited XBRL filings on SEC EDGAR and includes a 20-point insider component built from Form 4s, and a Korean company files neither, so a grade here would be measuring something different from the same letter on a US hub. These are the reported figures instead.

What Jusung Engineering does
Jusung Engineering builds deposition equipment, in particular atomic layer deposition, which lays down a film one atomic layer at a time. That level of control is what makes the structures in modern memory and logic possible, and it is a step that has grown in importance as features have stopped shrinking in the straightforward way they used to.
The company also sells into display and solar equipment, so the order book is not a pure semiconductor read. Like the other Korean tool makers, its customers are concentrated and its revenue arrives in lumps tied to capacity decisions, which makes a single quarter a poor guide to the trend.
Jusung Engineering is run by Hwang Chul-ju (황철주), founder and chairman, who started the company in 1993.
Jusung Engineering has no US listing. Buying the shares means buying the Seoul line, which most US brokerage accounts cannot do directly.

China's CXMT says its fifth-generation DRAM is in mass production and 'on par' with the industry's best
China's largest DRAM maker says its fifth-generation platform is in mass production, three weeks after its half-year report listed it as still in customer qualification. Two 24-gigabit LPDDR5X chips built on it are already in volume production.
Korea's 'K-Nvidia' is going public. Rebellions is leaning toward the Kosdaq, not the bigger Kospi.
Rebellions, the Korean AI chip company often called the 'K-Nvidia,' is preparing to sell its shares to the public. Rebellions is likely to file for a Kosdaq listing before the end of the year, valued at 3.4 trillion won ($2.5B), a change from the Kospi its founder first wanted.
Samsung and SK Hynix (SKHY) plan a memory expansion bigger than CXMT's entire projected capacity
A Bank of Korea report dated September 2 says Samsung's P4 and P5 fabs and SK Hynix's Yongin fab will add more than 600,000 wafers a month of memory capacity from 2028. China's CXMT is expected to reach 500,000 to 600,000 in total from the same year, and its shipments run far below its capacity. The bank still calls China a long-term threat.
Korea’s Kosdaq fell below 800 and left 307 companies facing delisting. Four sessions later it was up 24%.
Two weeks ago the Kosdaq was under 800 with 307 companies facing delisting tests. It has now risen 24% in four sessions, and on three of them the buying was fast enough that the Korea Exchange froze program orders, something that has never happened three days in a row before.
