Some analysts suggest that volatility in domestic semiconductor stocks is increasing as concerns about a slowdown in artificial intelligence (AI) development coincide with rising long-term U.S. interest rates. Noh Dong-gil, an analyst at Shinhan Investment Securities, stated, “It is not yet time to lower semiconductor profit forecasts based solely on discussions about slowing down AI development,” but added, “Nor is it the right time to rush into chase buying simply because demand is strong.” He continued, “Whether the U.S. 10-year Treasury yield stabilizes following this Federal Open Market Committee (FOMC) meeting will be the first condition to consider when deciding whether to increase exposure.”
