Market analysts noted that initial selling pressure due to geopolitical risks was countered by robust semiconductor exports and positive industry outlooks, which helped restore investor sentiment.
Im Jeong-eun, a researcher at KB Securities, stated, "From June 1 to 10, semiconductor exports reached $11.07 billion, a 205.8% increase compared to the same period last year, marking the highest level ever for this timeframe and driving recovery in sector investment sentiment. Given recent interest rate outlooks and market volatility, a fundamental-based approach to investing is necessary."
