7709.HK is trading at HK$42.94, with a -3.07% change; the September 22, 2026 decline most likely reflects profit-taking, daily reset effects, or trading-flow divergence rather than a fresh negative company-specific catalyst.
- The rally is supported by strong South Korean semiconductor exports, tight HBM capacity, and sustained AI-infrastructure demand.
- Exports rose sharply in September; SK Hynix remains a major HBM supplier benefiting from elevated demand.
- The leveraged ETF has recent sharp swings; price data is authoritative despite conflicting promotional headlines.
