The KOSPI opened with a jump of over 2.8%, or more than 200 points, compared to the previous trading day.
A sidecar, a temporary trading halt, was triggered early in the session, and the upward momentum intensified after 11:30 a.m.
The index ultimately closed at 8,096 points, up 8.18% from the previous day, marking a record-high single-day gain of 612 points.
In just one day, the market recouped 90% of the losses seen the day before.
Samsung Electronics and SK Hynix led the rally, surging approximately 9% and 16%, respectively.
The recovery in investor sentiment was largely driven by the announcement that Iran and Israel would cease attacks, which led to a significant jump in the stock prices of U.S. semiconductor companies overnight.
However, experts predict that market volatility will persist until the second-quarter earnings reports of major U.S. tech companies, including semiconductor firms, are released next month.
They point out that skepticism regarding a "peak" in the semiconductor industry is spreading through the market, given the steepness and speed of the recent stock price gains.

A series of major events are scheduled, starting with the U.S. Consumer Price Index (CPI) release tonight, followed by interest rate decisions in Japan and Europe.

The KOSPI 200 Volatility Index, often referred to as the "Korean fear index," reached 91.23, an all-time high that surpasses the levels seen when the war first broke out.
Experts advise investors to exercise caution and specifically warn against investing in leveraged products, which can suffer from the "negative compounding effect"—where it becomes impossible to maintain the principal amount during periods of extreme volatility.
