SK Hynix traded at 1,302,000 won (about $975) on November 12, 2026, up 1.96% on the day. That SK Hynix Korea stock price today is a midday Seoul quote from Yahoo Finance data. It leaves the stock 9.77% lower than a month ago and 13.43% lower than three months ago.
If you’re searching from São Paulo, Manila or New York, this page covers what moved the stock, how to read a price quoted in won, and how people outside Korea actually invest in the world’s best-known maker of AI memory. Nothing here is investment advice.
Key takeaways
- One SK Hynix share costs roughly $975 at 1,335.08 won per dollar (November 12, 2026), and Korea’s exchange sells whole shares only.
- The 1.96% gain came after the Philadelphia Semiconductor Index (SOX), the main US chip-stock benchmark, jumped 5.66% on November 11.
- Even after the bounce, SK Hynix is down 13.43% over three months, a smaller fall than the KOSPI’s 17.32%.
- The ticker is 000660 on the KOSPI. It trades 9:00 to 15:30 Korea time (UTC+9), which is 21:00 to 03:30 in Brasília.
What is the SK Hynix Korea stock price today?
At 11:41 a.m. Seoul time on November 12, 2026 (02:41 UTC, when the market data below was taken), SK Hynix was at 1,302,000 won per share. The market was still open, so treat this as a live snapshot. The closing price may differ.
Some quick math puts it in context. A 9.77% one-month drop means the stock stood well above today’s level in mid-October. A 13.43% three-month drop puts the mid-August level near 1.5 million won. So today’s rise recovers only a small part of an autumn slide.
SK Hynix didn’t fall alone. Here’s how it compares with the other big Korean names and the indexes, all from Yahoo Finance data dated November 12, 2026 (the SOX is dated November 11, the last US session).
| Asset | Last price | 1 day | 1 month | 3 months |
|---|---|---|---|---|
| SK Hynix (000660) | 1,302,000 won | +1.96% | -9.77% | -13.43% |
| Samsung Electronics (005930) | 212,750 won | +3.28% | -8.30% | -16.73% |
| Hyundai Motor (005380) | 269,500 won | -1.10% | -14.44% | -34.19% |
| KOSPI index | 5,439.59 points | +1.19% | -9.87% | -17.32% |
| KOSDAQ index | 706.16 points | +0.15% | -15.64% | -17.78% |
| Philadelphia Semiconductor Index (Nov 11) | 10,564.11 points | +5.66% | -13.47% | -14.80% |
| USD/KRW | 1,335.08 won per dollar | -0.51% | -0.39% | -5.46% |
A note on the names: the KOSPI is Korea’s main stock index, home to the big listed companies. The KOSDAQ is the smaller, tech-heavy second board. SK Hynix trades on the KOSPI, where it’s one of the two largest companies alongside Samsung Electronics.
Why did SK Hynix stock move on November 12?
The simplest explanation is the overnight lead from Wall Street. The Philadelphia Semiconductor Index rose 5.66% on November 11, and Korean chip stocks usually take their cue from US chip trading when Seoul opens. The customers for SK Hynix’s memory, Nvidia above all, trade in New York, so a strong US session tends to lift Seoul the next morning.
The Korean open was cautious, not euphoric. According to Chosun Ilbo, the KOSPI opened 0.2% higher “on mixed U.S. tech signals.” By late morning the index was up 1.19%, so buying picked up during the session.
The other force is foreign money. Yahoo Finance reported that Samsung Electronics shares rose 3.57% “as foreign buyers return to AI memory.” Our data snapshot shows Samsung up 3.28%. The gap comes from different timestamps within the same session, not a contradiction. Yahoo Finance also ran a separate piece asking why SK hynix moved today.
Put together: a big US chip rally, foreign funds buying Korean memory names again, and a market that had fallen far enough over three months to bounce. That’s what moved the price. One good day doesn’t tell you the slide has ended.
What we know from this week’s SK Hynix and Korea chip headlines
Below are the stories in this week’s coverage that bear on the SK Hynix share price. Each one is attributed to the outlet that published it, and we’ve limited ourselves to what their headlines state.
- Samsung packaging investment. Reuters reported that South Korean President Lee Jae-myung said a Samsung chip packaging expansion will spur $30 billion in additional investment. Packaging is the step where chips are stacked and connected, and it’s central to AI memory. That’s Samsung’s project, not SK Hynix’s, but it shows how much money is going into Korea’s memory supply chain.
- The economy leans on chips. Foreign Policy ran an analysis headlined “Memory Chips Are Completely Distorting South Korea’s Economy.” Chosun Ilbo took a similar angle with “Semiconductor Boom’s Butterfly Effect in South Korea.”
- Chip taxes are reaching the budget. BigGo Finance reported that South Korea’s fiscal deficit narrowed to 32 trillion won on a semiconductor tax windfall, the smallest in eight years.
- SK Hynix’s own message. The company’s newsroom published a piece on building trust in memory for “physical AI” (robots, vehicles and machines that run AI on the device), focused on safeguards against system failures and cyber threats. That points to where it wants demand to come from next, beyond data centers.
- Korean retail money is heading abroad. KED Global reported that Korean investors are flocking to US stocks and betting big on risky leveraged ETFs. When local savers buy abroad, foreign funds have more influence over the KOSPI.
You’ll also see US investing sites comparing SK Hynix with Nvidia; The Motley Fool ran one this week. That tells you how far the company’s name has spread among foreign retail investors. Treat those pieces as opinion, not data.
Why SK Hynix matters outside Korea: HBM and AI memory
SK Hynix makes memory chips: DRAM, the fast working memory in every computer and phone, and NAND flash, the storage in SSDs and smartphones. Its global profile today rests on one product: HBM.
What is HBM and why does Nvidia need it?
HBM, or high-bandwidth memory, is a stack of DRAM chips piled vertically and wired together so data moves to the processor much faster than with ordinary memory. AI accelerators such as Nvidia’s data-center GPUs sit next to HBM stacks because training and running large AI models is limited by how fast data can be fed in. SK Hynix co-developed the first HBM in 2013 and became the leading supplier to Nvidia. That’s why a rally in US AI stocks shows up in Seoul within hours.
Who owns SK Hynix?
SK Hynix is not part of Samsung. It began in 1983 as Hyundai Electronics, became Hynix Semiconductor in 2001 after leaving the Hyundai group, and was bought by SK Group (through SK Telecom) in 2012. SK is one of Korea’s chaebol, the family-run conglomerates that dominate the economy. For the longer story of how Korea built its chip industry, see our South Korea semiconductor industry explainer.
Why memory stocks swing harder than the market
Memory is a commodity-like business. When buyers stock up, chip prices and profits rise fast. When they stop, prices fall and so does the stock. HBM has softened this cycle somewhat because it’s made to order for specific customers. Still, SK Hynix’s one-month drop of 9.77% almost matches the KOSPI’s 9.87%, so on this move it traded more like the market than like a safe haven.
How to read the SK Hynix stock price from abroad
A won price with seven digits looks alarming if you’re used to US quotes. It’s just the currency. Here’s how to read it.
Ticker symbol and where to check the live price
- Korea Exchange code: 000660 (KOSPI market).
- Yahoo Finance: 000660.KS
- Google Finance: KRX:000660
- Official sources: the Korea Exchange (KRX) website for market data, and SK hynix’s investor relations page for earnings, filings and dividend notices.
Free sites often show Korean quotes with a delay. If the timing matters to you, check what delay your source applies.
KOSPI trading hours in your time zone
The regular session runs 9:00 to 15:30 Korea Standard Time (UTC+9). Korea doesn’t use daylight saving time. In mid-November that converts to:
- Manila, Singapore, Hong Kong (UTC+8): 8:00 to 14:30
- London (UTC+0): 0:00 to 6:30
- Brasília (UTC-3): 21:00 to 3:30, starting the evening before the Seoul date
- New York (UTC-5): 19:00 to 1:30, starting the evening before the Seoul date
That’s why a quote you check in Brazil on a Tuesday evening is really Wednesday’s Korean session.
Worked example: what the move means in dollars
Divide the won price by the exchange rate: 1,302,000 ÷ 1,335.08 ≈ $975 per share. Samsung Electronics works out to about $159.
Currency changes your return. Over three months the dollar fell 5.46% against the won, which means the won strengthened. A dollar-based holder lost 13.43% on the share price but gained on the currency, so the net loss in dollars was smaller than the 13.43% drop in the won price. On November 12, the stock’s 1.96% gain plus a 0.51% firmer won works out to roughly +2.5% in dollars.
How foreigners can buy SK Hynix shares
SK Hynix’s primary listing is in Seoul, so you can’t buy it the way you’d buy a US stock on most retail apps. Korea dropped its old investor registration requirement for foreigners at the end of 2023, but whether you can trade Korean shares still depends on your broker and your country. The main routes:
| Route | What you hold | Why people use it | What to watch |
|---|---|---|---|
| Broker with KRX access | Actual 000660 shares in won | Direct, full exposure to SK Hynix alone | Few retail brokers offer Korea; whole shares only; currency conversion fees |
| Korea country ETF (e.g., iShares MSCI South Korea ETF, EWY) | A basket of large Korean stocks, including SK Hynix and Samsung | Trades in dollars on US exchanges; easy to buy from most apps | SK Hynix is one holding among many; check current weights and fees on the issuer’s page |
| Global semiconductor or AI funds | A basket of chipmakers worldwide | Exposure to the whole memory and AI chain | Some funds hold SK Hynix, many don’t; read the holdings list |
The routes and paperwork are the same as for Samsung, which we walk through in detail in how to buy Samsung stock as a foreigner. Before you commit, ask your broker about Korean dividend withholding tax and how it’s handled in your country. Rules vary by tax treaty.

What we don’t know yet
- Whether “sold out through 2029” is accurate. Searches for “SK Hynix sold out 2029” are rising in the US. None of the reporting cited here confirms that SK Hynix has sold its memory output through 2029. Statements like that usually come from earnings calls, so check SK hynix’s investor relations transcripts rather than social media summaries.
- The single cause of the three-month slide. The stock fell 13.43% and the KOSPI 17.32% over three months. The headlines we have discuss Korea’s dependence on memory chips but don’t name one trigger, and we won’t guess.
- Whether foreign buying lasts. Yahoo Finance’s report of foreign buyers returning covers one session. KRX publishes daily foreign net-buying data if you want to follow it.
- The next profit numbers. SK Hynix normally reports fourth-quarter results in late January. The exact date appears on its investor relations calendar.
SK Hynix timeline: the dates behind today’s price
| Date | Event |
|---|---|
| 1983 | Hyundai Electronics founded, the company that became SK Hynix |
| 2001 | Renamed Hynix Semiconductor after separating from the Hyundai group |
| 2012 | SK Group acquires the company through SK Telecom; name becomes SK Hynix |
| 2013 | SK Hynix co-develops the first high-bandwidth memory (HBM) |
| Mid-Aug 2026 | Stock near 1.5 million won (implied by the 13.43% three-month decline) |
| Mid-Oct 2026 | Starting point of the 9.77% one-month decline to November 12 |
| Nov 11, 2026 | Philadelphia Semiconductor Index rises 5.66% to 10,564.11 |
| Nov 12, 2026 | SK Hynix at 1,302,000 won (+1.96%); KOSPI at 5,439.59 (+1.19%); won at 1,335.08 per dollar |
What to watch next for SK Hynix stock
If you’re tracking the SK Hynix Korea stock price from abroad, these are the things that move it, in rough order of how often they matter:
- The US chip session the night before. Check the SOX and Nvidia’s close before Seoul opens. Monday’s 5.66% SOX jump set up today’s move.
- Nvidia’s quarterly results. Nvidia usually reports its fiscal third quarter in late November; confirm the date on its investor relations page. Comments on AI chip demand there feed straight into HBM expectations.
- The won-dollar rate. A stronger won has cushioned dollar losses over three months. If that reverses, dollar returns get worse even when the won price holds.
- Samsung’s packaging push. Watch for details on the $30 billion investment Reuters reported, because Samsung is SK Hynix’s closest HBM rival.
- SK Hynix’s late-January results. This is where any claims about multi-year supply deals get confirmed or not.
FAQ
What is SK Hynix’s stock price in US dollars?
At 1,302,000 won and 1,335.08 won per dollar on November 12, 2026, one share is worth about $975. The dollar figure moves with both the share price and the exchange rate. Divide the live won quote by the live USD/KRW rate to get your own number.
Can I buy SK Hynix stock in the US?
SK Hynix’s primary listing is on the Korea Exchange, not a US exchange, so most US apps can’t buy it directly. People in the US usually get exposure through a broker with Korean market access or through funds that hold it, such as Korea country ETFs. Check the fund’s holdings and fees on the issuer’s website.
What is SK Hynix’s ticker symbol?
The Korea Exchange code is 000660. On Yahoo Finance it’s 000660.KS, and on Google Finance it’s KRX:000660.
Why is SK Hynix stock down this month?
SK Hynix fell 9.77% over the past month, almost the same as the KOSPI’s 9.87% drop, and the US chip index fell 13.47% over the same period. That points to a sector- and market-wide pullback rather than a company-specific shock. The headlines we reviewed don’t name a single trigger.
Is SK Hynix sold out until 2029?
Searches for this are rising, but none of the reporting cited here confirms it. Supply commitments like that are normally disclosed on earnings calls, so the reliable place to check is SK hynix’s investor relations page and its call transcripts.
Is SK Hynix part of Samsung?
No. SK Hynix belongs to SK Group, a separate Korean conglomerate, and it competes with Samsung Electronics in DRAM, NAND and HBM. The two are the KOSPI’s largest companies, which is why they often move together.
