Yonhap KOSPI continued its upward trajectory Tuesday, following news of a ceasefire agreement between the United States and Iran, though the pace of gains slowed compared with the previous session.

The country’s benchmark index opened at 8,696.55, up 150.57 points, or 1.76 percent, extending its winning streak to a fourth consecutive session.

The rally, however, lost momentum as trading progressed, with the index briefly falling to 8,540.41 around 10 a.m.

It later rebounded to close at 8,726.60, up 180.62 points, or 2.11 percent.
