The KOSPI rose more than 8% throughout trading on the 12th, regaining the 8,400 mark, but finished at 8,123 with reduced profits.
As reported by the Korea Exchange on the 12th, the KOSPI started at 8,263.85, increasing by 6.44% compared to the prior day. This marked the first occasion in three trading sessions where it surpassed 8,000. With gains during the session growing larger, a buy-side circuit breaker activated, causing a temporary pause in algorithmic purchases on the KOSPI. Nevertheless, the upward trend during the day weakened, resulting in a closing value of 8,123.62, which reflected an increase of 4.63%.
On the same day, Samsung Electronics and SK Hynix, considered the "top two" companies in the local stock market, finished trading at 322,500 South Korean won and 2,150,000 South Korean won respectively, rising by 7.86% and 2.33% compared to the prior day.
The robust showing of the stock market today stems from increasing hopes for a truce between the United States and Iran. On the 11th, U.S. President Donald Trump mentioned at the White House, "We've made a great deal to conclude the conflict with Iran, leaving just the last step of coordination," and noted, "The formal signing might happen in Europe as soon as this weekend." Following reports about the approaching conclusion of the Iranian conflict, which had been causing concern among investors, the U.S. S&P 500 and Nasdaq increased by 1.75% and 2.54%, respectively, finishing the day on a positive note.
