Samsung Electronics is trading at €3770.00, up 7.71% now, after reports that HBM4 production yield reached 80%.
- Yield rose from below 60% at mass-production launch and reportedly reached the industry’s “golden yield” threshold ahead of schedule.
- The improvement supports higher output, profitability and AI-memory competitiveness.
- The catalyst appears more influential than broadly flat markets, aligning with the strong August 11 advance; Seoul Economic Daily reporting was cited by multiple industry sources.
