SK Hynix Stages Historic Rebound as Chairman's First-Ever Share Purchase Bolsters AI Rally
Published on 07/31/2026 at 08:21 | Redaktion boerse-global.de
The whiplash hitting SK Hynix shareholders this week has been extraordinary even by the standards of Korea's notoriously volatile semiconductor sector. After watching nearly a third of the company's market value evaporate in just three sessions, investors witnessed the sharpest single-day advance in the memory chip maker's history — a surge that erased much of the damage and sent the stock to 1,704,000 won by Friday's close.
The 28.9 percent explosion in Seoul capped a remarkable reversal of fortune. Just 24 hours earlier, the shares had settled at 1,322,000 won, having been dragged down alongside rival Samsung Electronics on fears that the artificial intelligence spending boom was running out of steam. Those concerns now appear, at least for the moment, to have been pushed aside.

Wall Street's Cloud Numbers Ignite the Turnaround
The catalyst originated thousands of miles from Seoul. Microsoft's disclosure that its Azure cloud division grew 43 percent sent a powerful signal to global markets: the enormous capital outlays pouring into AI infrastructure are generating real returns. Amazon reinforced the message, reporting the fastest expansion in its AWS cloud business in more than four years.
For SK Hynix, the dominant supplier of high-bandwidth memory chips that power AI accelerators, the US earnings season provided direct evidence that demand from hyperscale data centers remains robust. The Philadelphia Semiconductor Index jumped 8.19 percent on Thursday, and SK Hynix's US-listed depositary receipts surged 17.52 percent overnight — setting the stage for Friday's historic move in the Korean market.
A Chairman's Personal Bet
Adding fuel to the rebound was an unusual development from within the company's own ranks. SK Group Chairman Chey Tae-won made his first-ever personal purchase of SK Hynix shares on the open market Thursday, acquiring 3,620 common shares for roughly 4.8 billion won. Market participants read the move as a deliberate vote of confidence following the recent correction — a gesture that carries weight no analyst commentary can match.
Record Quarter, Missed Expectations
The fundamental backdrop for the rally was laid on Wednesday, when SK Hynix reported second-quarter 2026 results that were spectacular in absolute terms yet somehow still disappointed the market. Operating profit surged 557 percent to 60.54 trillion won on revenue of 79.32 trillion won, a 257 percent increase. The operating margin hit 76 percent — a historic high for the company — while net profit reached 93.92 trillion won, boosted by non-operating investment gains.
The initial reaction was brutal: the stock fell nearly 9 percent following the release. Analysts had penciled in revenue closer to 84 trillion won, and long-term supply agreements had prevented SK Hynix from fully capitalizing on rising DRAM spot prices. Concerns about escalating capital expenditure added to the gloom. But Friday's rally demonstrated that investors have shifted their focus back to the structural strength of the AI memory market rather than the missed consensus targets.
The Nvidia Factor
Underpinning the medium-term narrative is a sweeping strategic partnership with Nvidia, finalized July 24 at the AI Summit in San Francisco. The multi-year alliance, valued at up to $500 billion, positions SK Hynix as the principal supplier of next-generation HBM4 memory modules — components central to Nvidia's forthcoming Vera Rubin AI platform. The agreement also encompasses joint development of next-generation AI memory chips and construction of a massive 2-gigawatt AI factory slated to come online in 2027.
Management confirmed during the earnings call that mass shipments of HBM4, the sixth-generation high-bandwidth memory, have commenced. To make revenue streams more predictable, SK Hynix has signed long-term supply contracts with roughly ten major global customers, securing sales for the next five years.
Margin Machine in DDR5
In parallel, the company is reallocating production capacity toward DDR5 memory, where severe supply shortages have driven margins as high as 90 percent. SK Hynix is deliberately expanding manufacturing in this segment, capitalizing on a market where demand continues to outstrip supply.
Perspective Check
The historic jump looks rather different when viewed against the longer price chart. Even after Friday's surge, the stock remains 42.95 percent below its 52-week high of 2,987,000 won, reached in June. Yet the year-to-date gain of 162.28 percent underscores how central SK Hynix has become to the global AI infrastructure buildout.

Whether Friday marks the beginning of a sustained recovery or merely a technical bounce fueled by short covering remains an open question. Industry signals are mixed: Samsung recently warned that memory shortages could persist into 2028, while some analysts caution about rising component costs in the second half of the year. What is clear is that SK Hynix has delivered a week that will be remembered for years — a record quarter, a landmark Nvidia deal, a chairman's personal stake, and a single-day surge that rewrote the company's history books.
