Following Samsung Electronics strong results on the 7th, domestic semiconductor stocks surged on the 8th as the United States and Iran agreed to a two-week ceasefire. Samsung Electronics rose more than 8 percent, topping 210,000 won, and SK hynix jumped more than 15 percent, surpassing 1,000,000 won.

As of 1:50 p.m., the KOSPI was trading at 5,905.59, up 410.81 points (7.48 percent) from the previous session. Having opened at 5,804.70, up 309.92 points (5.64 percent), the KOSPI later cleared the 5,900 level as semiconductor stocks extended gains.

Samsung Electronics was trading at 213,000 won, up 16,500 won (8.4 percent) from the previous session. During regular trading it climbed as high as 214,500 won, the highest since February 27, when it set an intraday record of 223,000 won.

SK hynix was trading at 1,055,000 won, up 139,000 won from the previous session. In the pre-market it even touched the 1.1 million won mark. Both stocks are quickly expanding gains as foreign investors turn heavy net buyers.

On the KOSPI market that day, individuals were net sellers of about 5 trillion won, while foreigners and institutions were net buyers of roughly 2 trillion won and about 2.7 trillion won, respectively, supporting the index.

The sharp rise in semiconductor stocks largely reflects stronger risk appetite following the U.S.-Iran ceasefire. In Japan as well, AI and semiconductor names such as Advantest, Tokyo Electron, and SoftBank were particularly strong.

In particular, sentiment toward memory semiconductors was buoyed by Samsung Electronics results that beat market expectations the previous day. After the earnings release, domestic brokerages moved to raise target prices for chipmakers, with some projecting 360,000 won for Samsung Electronics and 1.8 million won for SK hynix.
