Company snapshot — SK Hynix Inc

000660.KS in five paragraphs: what it makes and sells, where it sits in the Closelooknet stack, who it is priced against, why we track it, what we watch. Research diary, not advice.

What it does
SK Hynix designs and manufactures memory chips, including DRAM, NAND flash, SSDs and high-bandwidth memory used in servers, mobile devices, PCs, consumer electronics and automotive systems. It also runs a foundry business that makes non-memory semiconductors for customers. The company is headquartered in Icheon-si, South Korea, and sells across Asia, the United States and Europe.
Where it sits in the stack
In our index, SK Hynix sits in Layer 3, Assembly & Test, within the HBM Memory sleeve — the part of the AI compute stack where high-bandwidth memory supply has run short. Its output is a constraint on how many AI accelerators can be paired with enough memory bandwidth, since each accelerator needs stacked memory alongside it.
Who it is priced against
Closelooknet's peer group places it with the other memory makers — Micron Technology, Samsung Electronics, Sandisk, Western Digital and Seagate Technology — the set the market prices it against rather than a broader sector list; Kioxia is the additional name often mentioned alongside them.
Why Closelooknet tracks it
It holds a seat in our index and carries a Closelooknet score across several modules, with quality the strongest reading and momentum the weakest. The diary has quoted it in a dossier on the AI chip supply chain and in a report on the Nvidia ecosystem, where it appears among names tied to HBM4 supply.
What the diary watches
Whether HBM supply and demand stay tight enough to keep the quality reading firm even as the momentum reading lags.

SK Hynix Inc (000660.KS) trades on the KO exchange in South Korea, classified under Technology, and sits in Layer 3 of the build-out stack. Constituent of Rubin Build-Out 100.
