KOSPI surges early; SK Hynix and Samsung Electronics gain over 20%

Intraday reporting on July 31 described a sharp rebound in the KOSPI and major semiconductor stocks following declines through the previous day. Because percentage gains change throughout the session, opening figures, figures at the time an article was written, and closing prices should not be conflated.

The article cited net buying by foreign investors and a rebound in US technology stocks as background. The topic concerns considering trading time, volatility, and investor flows together, without treating one day's surge as proof of a long-term trend.
