True
The KOSPI index opened above the 7,100 mark on September 22, driven by a rally in semiconductor stocks. The benchmark index started the session at 7,153.99, keeping it above the 7,100 line in early trading. However, the index gave back its gains in the afternoon, slipping to the 7,049–7,053 range, leaving a close above 7,100 unconfirmed.
The session began with the KOSPI opening at 7,153.99, placing the market above the psychologically significant 7,100 threshold from the first minutes of trading. The opening strength was attributed to a semiconductor rally, with chip-related issues leading the market higher.
The morning momentum did not hold through the full session. By the afternoon, the index had surrendered its advance and traded in the 7,049–7,053 range, falling back below the 7,100 line. As a result, whether the market finished the day above 7,100 remains undetermined, and the intraday breakthrough stands only on the basis of the open and early trading.
The KOSPI did trade above 7,100 at the open and in the early part of the September 22 session, supported by a semiconductor rally, though the level was not sustained into the afternoon. The claim is True, with the caveat that the breakthrough applied to intraday and early-session figures rather than the closing price.
