SK Hynix’s Whiplash Week: Record Valuation, Sold-Out Fabs, and a Geopolitical Hangover
Published on 05/16/2026 at 06:21 | Redaktion boerse-global.de
The South Korean memory-chip giant capped a historic valuation milestone with one of its steepest single-session drops in months. SK Hynix saw its forward price-to-earnings ratio for 2026 climb to 6.79 on Thursday, nudging past archrival Samsung Electronics for the first time. By Friday, the stock had tumbled 7.66 percent to 1,819,000 Won, dragged down by a broad selloff that knocked 6.1 percent off the KOSPI. The retreat came after a blistering rally that left the shares up roughly 60 percent in 30 days and nearly 169 percent year-to-date.
The fundamental picture, however, remains extraordinary. SK Hynix reported an operating profit of 37.61 trillion Won for the first quarter, with an operating margin of 72 percent — a record for any semiconductor company. Management says DRAM, NAND and HBM inventories are completely sold out, and the company cannot fulfil all customer orders. Goldman Sachs analysts describe it as the worst supply shortage in 15 years. That scarcity is prompting some of the world’s largest tech firms to act as quasi-investors. Microsoft, Google and Amazon are reportedly planning billion-dollar commitments to pre-finance capacity expansions at SK Hynix, securing HBM chips years in advance.
The second-quarter outlook is even more aggressive. KB Securities expects operating profit to reach 70 trillion Won, a 660.4 percent jump year-on-year, with a margin of 78.1 percent — potentially the highest in the global chip industry. The brokerage has raised its price target eight times this year, most recently to 3 million Won. Macquarie followed with a 61 percent increase to 2.9 million Won, predicting that the global memory shortage will persist beyond 2027 and that HBM prices alone could climb more than 50 percent next year. KB also forecasts DRAM and NAND price gains of 194 percent and 244 percent respectively for the full year.
On the product front, SK Hynix has started mass production of SOCAMM2, a new memory module designed for Nvidia’s upcoming Vera Rubin platform, offering double the bandwidth and significantly improved energy efficiency. The second expansion phase of its Yongin Semiconductor Cluster fab is slated for August 2026, with investments running into the tens of billions of dollars. The company’s reliance on AI-driven demand is clear: in the first quarter, Nvidia accounted for 7.78 trillion Won in revenue, or 14.8 percent of the total, while an unnamed second customer — believed to be Microsoft or Google — contributed another 12.4 percent.
Should investors sell immediately? Or is it worth buying SK Hynix?
Yet the competitive landscape is shifting. Samsung has secured qualification for Nvidia’s new server platform and is targeting mass production of the next-generation HBM4 in the second half of 2026. If Samsung gains traction, SK Hynix could lose significant market share. Analysts warn that if its HBM share falls below 60 percent, the current premium valuation will come under pressure.
Friday’s rout was driven by a confluence of external factors. Tensions in the Strait of Hormuz weighed on risk appetite. A strike at Samsung Electronics, which began on May 21 and is expected to last 18 days, added to the unease — though it could theoretically help SK Hynix in the near term. Meanwhile, a US-China summit ended without a formal agreement on Nvidia chip exports, keeping the regulatory cloud over the sector. The KOSPI briefly touched 8,000 points before sliding 6.12 percent.
The technical picture shows no sign of a breakdown yet: the RSI sits at 68.9, elevated but not in extreme overbought territory. On Monday, the stock had actually jumped 13.4 percent to 1,912,000 Won before hitting a new year-to-date high of 1,976,000 Won on May 13.
SK Hynix at a turning point? This analysis reveals what investors need to know now.
Looking ahead, Macquarie notes that SK Hynix is exploring a US ADR listing, which could broaden its international investor base. A share buyback programme worth approximately 250 trillion Won over two years is reportedly under consideration. On May 27, South Korea’s financial regulator is set to list two-times leveraged products on SK Hynix, a move that could further amplify volatility. With that catalyst on the horizon, the $1 trillion market-cap zone becomes the next psychological battleground for a stock that refuses to settle down.
