Samsung Electronics and SK Hynix shares rose in early trading, buoyed by a strong performance in US semiconductor stocks fueled by growing AI demand.

What Happened

Semiconductor Rally: Despite a broader market decline in New York due to Middle East tensions, semiconductor stocks surged as AI demand optimism lifted the sector. Major players like Intel and AMD saw significant gains, driving the Philadelphia Semiconductor Index up by 1.30%.

Domestic Market Response: Reflecting the positive sentiment from the US, Samsung Electronics and SK Hynix opened higher on the 9th. SK Hynix, in particular, showed strong momentum following a sharp rise in its US-listed ADRs overnight.

Market Analysis: Analysts attributed the sector's strength to reaffirmed growth in AI demand during recent industry conferences. While the broader Korean market faces selling pressure from foreign and institutional investors, the semiconductor giants remain resilient.

Supply and Demand: Although foreign and institutional investors are net sellers in the domestic electronics sector, corporate entities have emerged as key buyers, providing support to the stock prices of major semiconductor firms.
