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 SK Hynix does
SK Hynix is a memory chipmaker and the largest supplier of high bandwidth memory, the stacked DRAM that sits beside a GPU and feeds it data. Every AI accelerator needs it, and there are only three companies in the world that make it. That position is why a memory company that used to trade on the commodity DRAM cycle now trades on AI demand.
The company sells the rest of its output as conventional DRAM and NAND flash, which still moves with the ordinary memory cycle. Management has said its long-term agreements with more than ten customers run three to five years and cover roughly half of revenue, with prices moving inside an agreed band rather than floating with the spot market. That structure is the mechanical reason a spot price spike does not flow through to SK Hynix the way it does to a competitor selling into the open market.
SK Hynix is run by Kwak Noh-jung (곽노정), President and CEO, since March 2022.
SK Hynix also has a Nasdaq listing, SKHY, where one American depositary share represents 0.1 of an ordinary Seoul share. It is a separate security with its own price and its own premium or discount to Seoul, so the two do not move by the same percentage on a given day.

Frequently asked questions
What is SK Hynix's stock code?
SK Hynix trades on the KOSPI in Seoul under the code 000660. Data providers usually write it as 000660.KS. SK Hynix also has a Nasdaq listing, SKHY, where one American depositary share represents 0.1 of an ordinary Seoul share. It is a separate security with its own price and its own premium or discount to Seoul, so the two do not move by the same percentage on a given day.
Why is SK Hynix an AI stock?
SK Hynix is a memory chipmaker and the largest supplier of high bandwidth memory, the stacked DRAM that sits beside a GPU and feeds it data. Every AI accelerator needs it, and there are only three companies in the world that make it. That position is why a memory company that used to trade on the commodity DRAM cycle now trades on AI demand.
What do analysts expect for SK Hynix?
38 analysts covering SK Hynix have an average price target of ₩3,096,288 (about $2,303), which is +105.3% against the last close. Coverage of Korean listings is overwhelmingly domestic, so these are Korean brokerage estimates rather than the US sell-side names that cover an American chip stock.
Does SK Hynix file with the SEC?
No. SK Hynix is a Korean company listed in Seoul, so it reports to the Korea Exchange and the Financial Supervisory Service, not the SEC. That is why this page has no filings, Form 4 insider or congressional trading sections: those are built from EDGAR, which has nothing on a company that does not file there.
