KOSPI rebounds 1.8 percent on institutional buying

KOSPI closed at 5,768 points on October 19, up 100 points or 1.8 percent. The benchmark reversed a 3.2 percent opening slide as institutions bought beaten-down large-cap shares, Yonhap reports.

Hyundai Motor was the strongest major stock named in the closing coverage, rising 4.5 percent to 326,000 won. Samsung Electronics also gained 1.2 percent, while bargain buying helped the market recover from its opening low.

Why did KOSPI reverse its early loss?

The index opened at 5,488 points, down 179.64 points or 3.2 percent from the previous close. It then recovered to finish at its intraday high of 5,768 points after institutions bought a net 574.66 billion won.

The reversal followed a technology-led sell-off on Wall Street and concerns about whether heavy artificial intelligence infrastructure spending will generate sufficient returns. The Economic Times linked the early weakness to those concerns.

Winners and losers in KOSPI

• Hyundai Motor up 4.5 percent.
• Samsung Electronics up 1.2 percent.

KOSPI recovers after a 5,488-point open

Friday's previous close was 5,668 points. Monday's opening level of 5,488 points marked the session low, while the 5,768-point close marked the high. The index therefore finished 100 points above the previous close after a sharp intraday reversal.

Samsung Electronics rose 1.2 percent to 218,000 won, and SK hynix gained 0.4 percent to 1.28 million won. Their recovery helped limit the impact of continuing semiconductor-sector concerns.
