[Edaily Reporter kyoungeun kim ] On the morning of the 30th, both the KOSPI and KOSDAQ are rising in tandem, buoyed by the overnight rally in the New York stock market.

According to MP Doctor, as of 9:14 a.m., the KOSPI is trading at 8,429.99, up 35.34 points (0.42%) from the previous trading day.

Earlier on the 29th (local time), the New York stock market saw its upward momentum limited in early trading due to a simultaneous decline in semiconductor stocks such as Micron and SanDisk. However, semiconductor stocks subsequently staged a sharp intraday rebound, leading to a close higher as rotation trading spread to other big tech companies including Alphabet (+4.82%), Tesla (+8.46%), Meta (+2.24%), and NVIDIA (+1.27%) as investors rotated into other big tech stocks, leading the market to close higher. The Dow Jones Industrial Average rose 0.59%, the S&P 500 index rose 1.18%, and the Nasdaq Composite rose 2.07%. The Philadelphia Semiconductor Index jumped 3.83%. President Trump’s announcement that U.S.-Iran peace talks would resume that day in Doha, Qatar, also boosted investor sentiment.

Han Ji-young, an analyst at KIWOOM Securities, said, “As this is the last trading day of June, volatility in the supply and demand of semiconductor stocks could increase toward the end of the session due to the impact of quarter- and half-year-end rebalancing, which may limit the market’s upside.”
