SK Hynix Inc stock (KR7000660001): shares slide after AI chip sector selloff and approach top of 52-week range

SK Hynix shares on the Korea Exchange fell sharply in Friday trading amid a broader AI-chip selloff sparked by a softer outlook from Broadcom, even as the stock remains near the upper end of its 52-week range after a powerful run over the past year.

SK Hynix Inc shares came under pressure in South Korea on 06/05/2026, declining by almost 10% on the Korea Exchange as part of a sector-wide pullback in AI-related semiconductor names that followed a softer outlook from U.S. chip supplier Broadcom, while the stock still trades close to the upper end of its 52-week range after a strong rally over the past year.

According to stock data for ticker 000660 on the Korea Exchange as of 06/05/2026, the SK Hynix share price fell from KRW 2,298,000.00 at the prior close to KRW 2,070,000.00, a one-day decline of 9.92%, in relatively active trading for one of South Korea's largest memory chip producers.

Sector reports from 06/05/2026 noted that SK Hynix stock dropped more than 8% in Seoul trading while Samsung Electronics also fell over 5% on the day, with both moves linked to profit-taking and a reassessment of AI-chip valuations after Broadcom's latest guidance update disappointed some investors and triggered a global selloff in semiconductor shares.

This price action anchors the stock firmly in its home market context, as SK Hynix is one of the most heavily traded semiconductor names on the Korea Exchange and an important component of South Korea's broader equity benchmarks that are closely watched by domestic and international investors alike.

Despite the sharp setback on 06/05/2026, data for SK Hynix over the past year show that the stock has delivered an exceptionally strong performance, with a 12-month gain reported at more than 800% and a 52-week price corridor between KRW 227,500 at the low end and KRW 2,407,000 at the high end of the range, underlining the scale of the prior rally.

At the same time, trading statistics highlight that the current share price level near KRW 2,070,000 as of 06/05/2026 keeps SK Hynix relatively close to the upper boundary of its quoted 52-week interval, so the recent correction comes from a notably elevated base compared with where the stock was trading one year earlier.

The domestic context is key for many retail investors, because South Korea remains SK Hynix's primary listing venue through the Korea Exchange, with KRW as the trading currency, even as international investors increasingly focus on the company due to its role as a critical memory supplier to leading global technology and AI players.

Some European investors may also look at the stock via secondary trading venues such as Tradegate in Germany, where SK Hynix certificates can provide an additional access point during European trading hours, although the primary liquidity and price discovery continue to occur in Seoul on the Korea Exchange.

Beyond equity market activity, SK Hynix continues to feature in industry news as a key customer and counterparty for equipment suppliers, and on 06/04/2026 a Korean equipment maker disclosed a KRW 21.2 billion contract related to chip manufacturing tools for SK Hynix, underscoring ongoing capital investment in advanced memory production capacity.

That same disclosure dated 06/04/2026 came alongside commentary that SK Hynix shares themselves had weakened on the day, suggesting that investors are parsing both capital expenditure plans and near-term sector sentiment when valuing major memory chip producers in the current environment.

The interplay of these short-term share price dynamics with longer-term investment decisions means that recent volatility in SK Hynix can be viewed both as a reaction to external sector triggers and as part of the normal fluctuation range for a stock that has already climbed sharply over the past twelve months.

Valuation metrics and multiples for SK Hynix Inc

For investors following SK Hynix from a valuation perspective, one reference point is that the stock has traded in a wide band over the last 52 weeks between KRW 227,500 on the downside and KRW 2,407,000 at the top of the reported range, highlighting both the volatility and the expansion in equity value that inform current valuation discussions.

With a one-year performance reportedly above 800% and the most recent closing price on 06/05/2026 at KRW 2,070,000, SK Hynix's valuation multiples such as price-to-earnings or enterprise-value-to-EBITDA are being assessed against expectations for continued growth in AI-driven demand for high-bandwidth memory and solid-state storage, even as the latest session's drop shows that these expectations are subject to rapid repricing on sector news.

Conclusion

The latest nearly 10% fall in SK Hynix shares on the Korea Exchange on 06/05/2026 illustrates how quickly sentiment toward AI-linked semiconductor stocks can reverse when a major sector player such as Broadcom offers a softer outlook.

At the same time, valuation indicators like the stock's 52-week range between KRW 227,500 and KRW 2,407,000 and its more than 800% gain over the past year indicate that the correction is occurring against a backdrop of substantial prior appreciation, which continues to shape how investors frame potential risks and opportunities in the name.

Market participants will now watch whether SK Hynix's strong positioning in DRAM and NAND for servers, smartphones and AI data centers, together with ongoing capital investment signaled by recent equipment orders, is sufficient to support current valuation levels in an environment where sector expectations are being recalibrated in real time.
