Samsung Electronics Stock Falls Over 4% on Foundry, Competition Concerns

Shares of Samsung Electronics Co Ltd (KS:005930) fell 4.1% to ₩258,000 on Friday, as investors reacted to a confluence of negative company-specific reports and broader market anxiety driven by rising bond yields and oil prices.

Key Pressures on the Stock

The sell-off was fueled by several distinct headwinds for the South Korean technology giant:

• Foundry Business Concerns: A report cited potential delays in Samsung's foundry unit securing a contract to manufacture Qualcomm's processors using its 2-nanometer technology. According to the report, this delay has raised questions about Samsung's ability to lock in Qualcomm as a major client for its advanced chipmaking processes.
• Increased Competition: Apple Inc. (NASDAQ:AAPL) unveiled its first foldable phone, the iPhone Duo, on September 9. Priced at $1,999, it directly competes with Samsung's recently launched Galaxy Z Fold 8, which sells for $1,899. The entry of a major rival into a market segment Samsung has dominated added to investor concerns.
• Market Share Erosion: Market research firm Counterpoint projects that Apple could capture 25% of the foldable phone market this year. While Samsung is expected to retain a leading 38% share, the forecast signals a significant erosion of its previous dominance in the premium category.

Broader Market Context

Beyond company-specific news, a warning from the Bank of Korea on September 10 may have contributed to the negative sentiment. The central bank highlighted the growing influence of foreign capital from hedge funds and leveraged products on Korean equities, with a specific focus on concentrated positions in Samsung and SK Hynix Inc (KS:000660).

The substantial losses in these two chipmakers were a primary driver behind the broader market decline on Friday, pulling South Korea's benchmark KOSPI index down by more than 2%.
