- Improved confidence in AI infrastructure spending helped lift memory-chip sentiment across the sector.
- Further gains were limited after Samsung shares had advanced 3.57 percent on Wednesday.
Samsung Electronics stock gained in early trading on Thursday, November 12, 2026, as a rally in US semiconductor shares improved sentiment across South Korea's chip sector. Yonhap, in a report published by Pulse, said the shares traded at 209,500 won at 9:21 a.m. local time, 1.7 percent above the previous session.
US Chip Gains Lift Seoul Sentiment
The move followed an overnight advance in US technology markets. The Nasdaq Composite rose 1.6 percent, while the Philadelphia Semiconductor Index jumped 5.66 percent. Memory-chip producers led the US gains, with Micron Technology rising 11.89 percent and Sandisk climbing 13.69 percent.
Investor confidence also benefited from strong results at AI-focused cloud provider CoreWeave, which eased concerns about credit risks linked to AI infrastructure investment. Reports of strong demand for Anthropic's planned Nasdaq offering added to the positive tone around AI-related shares.
Previous Gains Tempered The Advance
Samsung shares had already risen 3.57 percent on Wednesday, limiting the scope for a further move at the start of Thursday's session. The stock opened at 208,500 won, briefly touched 206,000 won and then recovered, according to the Pulse report.
The broader market picture remained mixed. Foreign and institutional investors were net sellers across the Kospi in early trading, while retail investors bought shares. In the electrical and electronics sector, institutions also sold stock, although individuals and foreign investors were net buyers.
Investor Focus Stays On AI Demand
For investors, the session underlined how closely Samsung's trading performance remains linked to expectations for AI infrastructure spending and demand for memory chips. The immediate driver was a change in sector sentiment rather than a new company announcement, so the direction of US chip stocks remains an important near-term influence.
