Shares of SK Hynix surged 11.3% to $1,185 on August 4, recovering most of the prior session's 8%-plus plunge on Seoul's KOSPI, as bargain hunters moved in following a wave of profit-taking tied to fears that AI-linked stocks had run too far, too fast. The whiplash raises a pointed question: is this a healthy reset or a warning that the chip giant's valuation has outpaced even its record earnings? SK Hynix Bounces 11% After Seoul's AI Panic Selling — Is the World's Hottest Chip Stock a Bargain or a Trap?
Shares shifted violently as SK Hynix's global depositary shares surged 11.3% to $1,185 on August 4, clawing back from a brutal 8%-plus sell-off on KOSPI the day prior. The whiplash comes despite record quarterly results and underscores a deepening tug-of-war between staggering profits and the fear that AI chip stocks have simply run too far ahead of themselves.
• Record Earnings Weren't Enough to Prevent the Rout. SK Hynix posted Q2 2026 revenue of ₩79.3 trillion — up 257% year-over-year — with operating profit soaring 557% to ₩60.5 trillion and an all-time operating margin of 76%. Yet the company fell short of revenue expectations, and its stock price slumped.
Despite strong fundamentals, the stock had already suffered a 30% correction amid valuation concerns and high ADR premiums. The August 3 plunge was the latest chapter in that sell-the-news pattern — investors are pocketing gains faster than the company can print them.
• The AI Money Machine Is Real, But So Is the Pricing Risk. SK Hynix began shipping its next-generation high-bandwidth memory (HBM4) in Q2, with full production ramp planned for the second half of 2026.
DRAM prices surged 30% in the quarter, and NAND prices rose in the mid-50% range. Those price spikes, driven by constrained supply, are the engine behind the 76% margin — but they invite the obvious question of sustainability. The rapid growth of Chinese memory manufacturers could lead to excessive capacity, significantly eroding prices.
• Dip-Buyers Are Betting on Locked-In Demand. SK Hynix raised full-year capital spending guidance to the high ₩40 trillion range and signed multi-year supply deals with roughly ten key customers. Management dismissed fears of an AI investment slowdown.
Net cash swelled to ₩69.4 trillion after a landmark Nasdaq ADR listing , giving the company a fortress balance sheet. That is the bull case fueling today's rebound — contractual revenue visibility rarely seen in the cyclical memory business.
• The Stock Is Still Deeply Below Its Peak Despite Monster Profits. SKHY fell roughly 35% in July alone, from approximately $194 to $124.80.
The average 12-month analyst target sits at ₩3.16 million — more than double recent levels — and all 38 covering analysts rate the stock a buy. The unanimous consensus suggests Wall Street sees the sell-off as a sentiment correction, not a fundamental one. For shareholders, the question is whether today's bounce marks the floor — or just a pause before AI's valuation reckoning resumes.
