SK Hynix’s move above $1 trillion and the market’s re-rating of high-bandwidth memory sharpen focus on AI data-centre bottlenecks, Korea index concentration and margin dynamics that investors monitor through the next supply cycle.
In the final trading sessions of May, Abishai Financial Asia Pte. Ltd. is tracking a renewed surge in high-bandwidth memory as SK Hynix trades above the $1 trillion market capitalisation line and stands about 248% higher over the opening five months of trading to the latest close.
Artificial intelligence data centres remain the driver, with memory pricing doubling over the opening quarter and forecasts continuing to point to further increases that reach as much as 63% over the quarter now under way.
High-bandwidth memory, the stacked DRAM that sits alongside advanced AI processors, now acts as the bottleneck that sets delivery schedules and pricing.
Daniel Coventry, who is director of private equity at Abishai Financial Asia Pte. Ltd., reduces the valuation move to four words: “a supply story first”, with capacity allocation setting the pace for pricing and sentiment.
In Wednesday’s session, SK Hynix rises as much as 14.9% intraday and finishes 9.3% higher, leaving the company valued at about $1.1 trillion at the close. In the latest quarterly statement, operating profit totals roughly $24.8 billion on revenue of about $34.7 billion, an operating margin of 72% for that reporting period, while net profit prints around $26.6 billion and a 77% net margin in the same quarter.
Industry indicators show why the market focuses on mix and scarcity. In the most recent quarter tracked by Counterpoint Research, SK Hynix captures 57% of global high-bandwidth memory revenue, while Samsung and Micron hold 22% and 21% across that same snapshot. On contract pricing disclosures from the opening quarter, select DRAM pricing rises 83% quarter-on-quarter and NAND pricing advances 160% over the same period, while company guidance continues to point to customer demand that exceeds planned high-bandwidth memory allocation for the next three years.
Index construction turns the theme into a benchmark issue. Samsung Electronics and SK Hynix together represent more than 40% of the Kospi on the latest weightings, and Nvidia’s latest fiscal quarter, with revenue of about $77.9 billion and data-centre revenue of roughly $71.8 billion in that period, keeps attention fixed on the AI hardware stack that depends on high-bandwidth memory supply.
Abishai Financial Asia also flags the risks that accompany concentration, with Coventry noting that “when two stocks dominate an index, the index becomes a single-factor position, so liquidity and position sizing discipline matter as much as conviction”. Retail margin balances in Korea rise to about $24.1 billion on the latest brokerage snapshot, and scenario analysis under prevailing rules shows a 10% decline in either stock pulling maintenance ratios from around 140% to below 120% within days. Foreign investors register net sales of roughly $3.5 billion in SK Hynix and about $3.5 billion in Samsung over the latest completed trading week.
Analyst targets continue to adjust. In bank updates released this month, UBS lifts its target to about $1,122 a share and raises earnings-per-share projections for the next two fiscal years by 22% and 29% respectively, while other houses place targets from around $2,046 to $2,112 over the coming year.
Supply agreements and market forecasts underline the structural constraint. Projections point to an addressable high-bandwidth memory market of around $110.7 billion within the next few years, up from roughly $38.7 billion over the latest full-year baseline, and roadmaps indicate global high-bandwidth memory bit requirements for AI server accelerators expanding by about 35 times over the four-year horizon now in focus. On the latest capacity estimates, Samsung, SK Hynix and Micron control about 95% of global DRAM output, and the high-bandwidth memory segment remains similarly concentrated, with SK Hynix near 62%, Micron at 21% and Samsung at 17% in the most recent reading. Disclosures also suggest SK Hynix secures more than two-thirds of Nvidia’s HBM4 requirements for its Vera Rubin platform due for deployment later in the year, with around 90% of Nvidia’s high-bandwidth memory sourcing tied to SK Hynix in the present supply mix.
For investors, scarcity can deliver exceptional margins and abrupt volatility in the same stretch of trading. In that environment, Abishai Financial Asia focuses on the mechanics that matter, where capacity allocation drives pricing, index structure amplifies moves and risk controls determine whether returns are kept or given back.
