July 13, 2026, saw the Korea Composite Stock Price Index (KOSPI) trigger its SIDECAR temporary suspension mechanism during trading, halting programmatic sell orders for five minutes. Storage chip giant SK Hynix (Korean stock code: 000660) was at the center of this sell-off, with its share price plunging over 10% at one point, hitting a low of 1.96 million KRW.
According to Gate’s Korean stock market data, as of July 12, 2026, SK Hynix was quoted at $1,260 (approximately 2,106,000 KRW), down 12.7% for the day. Its US ADR closed near $168 last Friday (July 10).
This sharp drop stands in stark contrast to the previous week, when SK Hynix’s ADR surged 12.76% on its Nasdaq debut. What caused such a dramatic reversal in market direction over just one weekend?
Geopolitical Risks Spike, Global Risk Appetite Plummets
In the Asia-Pacific early session on July 13, geopolitical factors became the primary catalyst for global risk-off sentiment. Over the weekend, the US announced the termination of its ceasefire agreement with Iran. In response, Iran blocked the Strait of Hormuz—one of the world’s most critical energy shipping routes—and the US military launched additional airstrikes at 6 a.m. Korea time on July 13.
As a result, international oil prices soared. WTI crude broke above $74 per barrel, and Brent crude climbed more than 3%. The sudden spike in energy prices fueled concerns about persistent inflation and slowing economic growth. Investors worldwide quickly shifted toward risk aversion.
For the Korean stock market, the impact of geopolitical risk was especially pronounced. Korea’s heavy reliance on energy imports and its export-driven economy make it highly sensitive to Middle Eastern tensions. As one of Korea’s largest semiconductor companies by market capitalization, SK Hynix became a prime target for foreign investors to reduce exposure. Some institutions adopted an "ADR long, Korea short" arbitrage strategy, further intensifying selling pressure in the domestic market.
Renewed Fears of AI Compute Surplus Weigh on Storage Chip Sector
Geopolitics triggered the immediate sell-off, but SK Hynix’s deep correction has more fundamental industry roots—concerns about an AI compute surplus have been mounting since early July.
On July 2, news that US tech giant Meta planned to sell excess AI computing power sent shares of leading Japanese and Korean storage chip makers tumbling. Samsung Electronics, SK Hynix, and Kioxia Holdings all fell more than 5%. The market logic: If AI investments fail to generate sufficient revenue, cloud service providers will need to sell surplus compute to maintain cash flow.
This concern isn’t isolated. The Bank for International Settlements previously warned about overheated AI investment, noting that the five largest hyperscale cloud providers—Google, Microsoft, Amazon, and others—plan to invest over $1 trillion in AI-related business between 2025 and 2026. If this investment boom reverses, it could trigger financial system turmoil.
Despite data from TrendForce showing global AI infrastructure and compute investment growth will reach 51% year-over-year in 2026, that’s a sharp slowdown from 104% in 2025. This deceleration alone is enough to prompt a valuation correction in semiconductor stocks that had seen outsized gains.
Looking at the broader Korean market, the KOSPI has dropped sharply for three consecutive weeks, falling more than 17% from its June 19 historic high of 9,385.59. SK Hynix and Samsung Electronics have both retreated around 30% from their annual peaks. In this environment, any negative catalyst tends to be amplified.
Institutions Lower Q2 Earnings Forecasts, "Good News Priced In" Becomes Sell Trigger
On July 13, a report from Korea Investment & Securities, a major domestic brokerage, became the direct catalyst for the sell-off.
The firm forecast SK Hynix’s Q2 2026 operating profit at 60.4 trillion KRW, about 8% below the consensus estimate of 65 trillion KRW. It projected Q2 revenue at 80.9 trillion KRW, up 264% year-over-year.
These figures need to be understood from two angles.
In absolute terms, 60.4 trillion KRW in operating profit means a 556% year-over-year increase, with a record operating margin of 74.6%—still an exceptionally strong performance. The issue isn’t that SK Hynix "isn’t making money," but rather that it may not be "as profitable as the market previously expected."
The shortfall stems from structural characteristics of the HBM business. Korea Investment & Securities pointed out that SK Hynix’s revenue from HBM is higher than its competitors, and HBM product prices are mostly set through long-term supply agreements (LTAs) signed in advance. This means the company can’t fully benefit from rapid spot market increases in DRAM prices, resulting in average selling price (ASP) growth below the market average.
Meanwhile, Q2 shipments of HBM4 reportedly fell short of market expectations, further fueling investor reassessment of whether high valuations can be matched by profit growth.
Korea Investment & Securities also lowered its operating profit forecasts for SK Hynix by 9% for 2026 and 11% for 2027, but emphasized this wasn’t due to earnings concerns. Rather, it reflects more realistic price assumptions based on existing long-term agreements. The firm maintained its target price of 3.8 million KRW.
ADR Listing Spurs Arbitrage and Valuation Reassessment
SK Hynix officially listed on Nasdaq on July 10, issuing ADRs at $149 each and raising about $26.5 billion—the largest US IPO by a foreign company to date. The stock opened at $170, hit an intraday high of $177, and closed at $168.01.
Yet, the surge in US ADRs didn’t boost the domestic Korean share price. Instead, it created a complex arbitrage structure.
Data shows SK Hynix’s ADR closed about 15.78% above its domestic share price. According to Seoul Kyobo Life Insurance’s active equity management chief, historically, there’s typically a structural valuation gap of around 15% between local listings and ADRs for global giants, mainly due to currency and regulatory differences.
The issue is that upside momentum in the US market was fully anticipated and priced in before the ADR debut. Once ADR trading began, some funds opted for "ADR long, Korea short" arbitrage, directly suppressing the domestic share price. Meanwhile, Korean shares that had rallied on ADR listing expectations faced heavy profit-taking.
Valuation at Historic Lows, but Market Sentiment Drives Short-Term Price Action
From a valuation perspective, SK Hynix isn’t expensive at current levels. As of July 9, KOSPI’s 12-month forward P/E ratio had dropped to about 6x, below levels seen during the 2008 financial crisis. SK Hynix’s own forward P/E sits between 4.8x and 6.8x, well below the industry median of 29.84x.
Low valuations mean the market has already priced in considerable pessimism. But as July 13’s trading showed, in the face of multiple negative factors, low valuations alone aren’t enough to halt short-term declines.
The Bank of Korea remains optimistic about the semiconductor sector’s medium- to long-term outlook. In its July 13 report, it stated that the global semiconductor market is still undersupplied, and the AI-driven chip supercycle is expected to continue. The central bank believes this chip cycle is driven by expectations that AI adoption will fundamentally reshape industry ecosystems, differing from previous cycles.

Conclusion
SK Hynix’s sharp decline on July 13, 2026, was the result of multiple factors converging: a sudden spike in geopolitical risk triggered global risk aversion; renewed concerns about AI compute surplus have weighed on semiconductor valuations since early July; Korea Investment & Securities’ downward revision of Q2 earnings forecasts acted as a direct catalyst—even though 60.4 trillion KRW in operating profit remains robust in absolute terms, the miss versus the 65 trillion KRW consensus prompted a "expectation gap" correction; ADR listing-driven arbitrage further intensified domestic selling pressure.
From a broader perspective, this sell-off reflects a shift in AI-related market pricing from "expectation-driven" to "validation-driven." Investors are no longer satisfied with the narrative of AI demand—they now want to see demand translate into verifiable orders, profits, and capital returns.

Frequently Asked Questions (FAQ)
Q1: What were the main reasons behind SK Hynix’s sharp drop on July 13?
The decline was driven by multiple factors: heightened geopolitical risk (escalating US-Iran conflict) triggered global risk aversion; Korea Investment & Securities’ Q2 operating profit forecast missed consensus by about 8%; persistent concerns about AI compute surplus weighed on the semiconductor sector; and ADR listing-driven arbitrage and profit-taking added further pressure.
Q2: Is there a fundamental problem with SK Hynix’s performance?
Not in absolute terms. The forecast for SK Hynix’s Q2 operating profit is 60.4 trillion KRW, up 556% year-over-year, with a record operating margin of 74.6%. The issue is that this figure is below the previous consensus of 65 trillion KRW, prompting a correction based on the "expectation gap."
Q3: What is the structural issue with SK Hynix’s HBM business?
SK Hynix has a higher revenue share from HBM, but HBM prices are mostly set through long-term supply agreements, so the company can’t fully benefit from rapid spot market DRAM price increases. This results in average selling price growth lagging behind the market.
Q4: How can I trade SK Hynix stock on Gate?
On Gate, SK Hynix’s trading code is SKHYNIX; the direct equity code is 000660. Users can trade via the Gate stocks section, choose the SKHYNIX/USDT CFD contract (with 4x leverage), SKHYG tokenized securities (24/7 trading), or SKHY perpetual contracts (1-10x leverage).
Q5: What is SK Hynix’s current valuation level?
SK Hynix’s 12-month forward P/E is between 4.8x and 6.8x, significantly below the industry median of 29.84x and lower than US competitor Micron Technology. Valuation is at historic lows, but short-term price action remains dominated by market sentiment and multiple negative factors.
