The KOSPI has reached a new high, with some reports indicating it has surpassed 8,000, while others suggest it has jumped past 4,300, 6,300, or gained around 4-5%. The surge is attributed to gains in stocks such as SK Hynix, with the company's stock rising 7% in one report and over 10% in another. The rally is also linked to other chip stocks, including Samsung Electronics, which has seen significant gains, although the exact levels of the KOSPI and individual stocks are unclear.
