Domestic optical communication and optical semiconductor-related stocks fell across the board during trading on the 2nd. Weakness in U.S. semiconductor stocks combined with declines in domestic semiconductor large-caps such as Samsung Electronics and SK Hynix, causing selling pressure to spread throughout the sector.

That afternoon in the KOSPI and KOSDAQ markets, large-cap semiconductor stocks led the downward trend, dampening investor sentiment. In particular, a wave of profit-taking hit growth stocks tied to AI and semiconductors, dragging optical communication and optical semiconductor stocks lower as well.

■ Major Stock Movements

• Daehan Optical Communication: Traded at 12,160 won, down 1,690 won (12.20%) from the previous trading day
• Kwangje Optech: Fell 10.40% to 6,120 won
• Bitgwajeonja: Fell 11.33% to 2,035 won
• Seoul Semiconductor: Traded at 10,220 won, down 9.88%
• RF Materials: Fell 13.19%
• RFHIC: Fell 9.61%

The optical communication and optical semiconductor sectors had been in the spotlight driven by expectations of benefits from the expansion of AI data centers, the buildout of ultra-fast networks, and increased investment in optical communication infrastructure. However, on this day, most related stocks underwent a correction due to weakness in global technology stocks and deteriorating investor sentiment.

In the market, the outlook that demand for optical communication modules, optical semiconductors, and optical cables will increase over the medium to long term amid the expansion of the AI industry remains valid. However, some analysts note that in the short term, the trend of U.S. semiconductor stocks and changes in supply and demand in the domestic stock market could increase price volatility for related stocks.
