SK Hynix Rides Nvidia’s Coattails Back From the Brink — But the Wild Swings Aren’t Over

After an 8% plunge on Fed rate hike fears, SK Hynix surged 16% following a multi-year Nvidia deal to co-develop memory for AI supercomputers and robots, highlighting extreme volatility.

The whiplash hitting SK Hynix shareholders is almost as extreme as the chipmaker’s latest technology partnership. After a brutal 8% plunge on Monday, the stock roared back some 16 percent on Tuesday, recouping virtually all of the prior session’s losses. The catalyst? A freshly disclosed, multi-year alliance with Nvidia that ties the Korean memory giant directly to the AI powerhouse’s hardware roadmap — from Vera Rubin supercomputers to Jetson Thor robotics platforms.

From Kospi Meltdown to Snap Rebound

Monday’s sell-off knocked the Kospi down 8.3 percent, fueled by red-hot US jobs data that reignited fears of further Federal Reserve rate hikes. Samsung Electronics slumped more than 10 percent, while SK Hynix shed nearly 8 percent of its value, closing at around 1.91 million won. By Tuesday, the Korean benchmark had bounced 8.2 percent to roughly 8,097 points, erasing almost the entire previous day’s rout. SK Hynix led the charge, climbing to 2,215,000 won — a level that now stands almost 48 percent above its 50-day moving average.

Deeper Than a Supply Deal

The partnership announced on June 7 goes well beyond a standard purchase order. SK Hynix will co-develop custom high-performance memory solutions tailored to Nvidia’s Vera Rubin AI supercomputers, Vera CPUs, RTX Spark PCs, and the Jetson Thor platform for autonomous robots. The agreement also integrates Nvidia’s CUDA-X libraries and PhysicsNeMo into chip design, while Omniverse tools will be used to build digital twins for SK Hynix’s own production lines. Nvidia CEO Jensen Huang underscored the strategic weight, describing the Korean firm as Nvidia’s largest memory partner going forward. For SK Hynix, the deal secures early access to Nvidia’s evolving specifications and locks in a structural role across the entire AI hardware cycle.

Volatility as a Feature, Not a Bug

Despite Tuesday’s sharp recovery, the one-week performance still shows a loss of roughly 6 percent on some measures, and the secondary source notes a steeper 19% weekly decline from earlier in the month. The annualised 30-day volatility stands at close to 99 percent — a level that puts the stock squarely in high-risk territory. Since the start of 2024, though, SK Hynix has soared more than 227 percent (or 182% per the secondary article, depending on the precise timeframe), with a 52-week high of 2,407,000 won touched on June 2 — a level still about 8 percent above the current price. That recent record of roughly 2.4 million won now sits behind a consolidation phase, but the underlying narrative remains unchanged: investors are treating the stock as a leveraged play on the global AI chip cycle, not a steady dividend payer.

The market’s message is clear. Macro shocks like Monday’s hit disproportionately hard — and the snapbacks are equally violent. Anyone holding SK Hynix shares is effectively riding one of the most volatile names in the global technology sector, now tethered to Nvidia’s ambitions from supercomputers to factory floors.
