SKHY is the U.S. ticker for SK hynix Inc., the South Korean memory chipmaker whose primary listing has long been on the Korea Exchange under the code KRX: 000660. The U.S. shares began trading on the Nasdaq in July 2026; the exchange code NMS in the quote panel refers to the Nasdaq Global Select Market. The price above is in U.S. dollars and reflects Nasdaq trading. The Korean line trades in won during Seoul hours, so the two quotes move on different clocks and in different currencies.

Reading the SKHY quote

The headline figure is the latest Nasdaq price, with the percentage change measured against the previous close, which is the final price of the prior U.S. session. The timestamp shows when that reading was taken. A quote stamped at 21:00 UTC lines up with the 4:00 p.m. Eastern close during U.S. standard time.

• Day range is the low and high traded during the current U.S. session only.
• 52-week range is the lowest and highest price over the trailing year. For a stock that listed in the U.S. in 2026, that window covers only the time since listing, not a full year of trading. The Korean listing is the longer record.
• Volume counts SKHY shares traded on U.S. venues. It excludes trading in the Seoul line.
• Performance tabs (1D, 5D, 1M, 6M, 1Y) compare the current price with the price at the start of each window. When a window is longer than the stock’s U.S. trading history, the comparison starts from the earliest available price. That is why two tabs can show the same figure.

SKHY and KRX: 000660

The two lines represent the same company but trade on separate markets. The Korea Exchange’s regular session runs from 9:00 a.m. to 3:30 p.m. Korea Standard Time, which closes before Nasdaq opens. As a result, SKHY often opens by absorbing whatever happened in Seoul overnight, which can show up as a gap at the Nasdaq open, and the Korean shares open the next morning reacting to the U.S. session.

Comparing the two prices directly needs two adjustments: the won to dollar exchange rate and the number of Korean shares each U.S. share represents, which the listing documents set out. Currency moves alone can push the U.S. price even on a day when the Korean shares close flat.

The Korean shares are a major weight in the KOSPI index, alongside Samsung Electronics. Swings in SK hynix can move the Korean benchmark, and broad selling in Korea can pull on SKHY.

What SK hynix does

SK hynix makes memory chips: DRAM, the working memory in servers, PCs and phones, and NAND flash, the storage inside solid-state drives. It also produces high-bandwidth memory (HBM), stacked DRAM placed next to AI accelerators in data center hardware. Its U.S. based subsidiary Solidigm, built from the NAND and SSD business it bought from Intel, sells enterprise storage drives.

What moves the stock

Memory prices and the chip cycle. DRAM and NAND are sold in large volumes, and their prices rise and fall with the balance of supply and demand. When prices climb, memory makers’ margins can expand quickly. When supply catches up, the same leverage works in reverse.

AI infrastructure spending. Data center buildouts by large technology companies drive demand for HBM and high-capacity server memory. Announcements about how much those companies plan to spend feed directly into expectations for SK hynix’s sales.

Expectations versus results. Earnings can grow very fast and still disappoint if the market was priced for more. In 2026, a broker forecast that SK hynix’s quarterly operating profit would miss estimates despite growth of more than 550% year over year coincided with a record one-day drop in the Korean shares.

Peers and sector indexes. SKHY tends to trade alongside Micron, Samsung, storage names such as SanDisk and Western Digital, and the PHLX Semiconductor Index (SOX). Earnings from TSMC and ASML, which signal the health of advanced chip demand, can move memory stocks as well.

Capital returns. SK hynix has set a target of returning at least 50% of free cash flow to shareholders. It has used share repurchases followed by cancellation of the bought-back shares, and its board has approved considering special dividends. Changes to these programs affect share count and payouts.

Practical caveats

SK hynix has been a highly volatile stock, with several double-digit daily moves in the same month during 2026. Swings of that size can leave a wide gap between the day range and the previous close and can trigger stop orders well away from their set price. A stop becomes a market order once triggered, and in a gap the fill can land below the trigger.

Because the Nasdaq and Seoul sessions don’t overlap, U.S. holders carry overnight risk every trading day. Concentration also matters: SKHY, Micron and memory-focused ETFs often move together, so holding several of them adds exposure to one industry cycle rather than spreading it.
