KRX activates buy-side sidecar for KOSPI on sharp rise

The Korea Exchange (KRX) has activated a buy-side sidecar for the KOSPI index following a sharp rise in the benchmark stock price index. The KOSPI, which had risen 2.05 percent to 5,800.55 in the morning, gained 247.81 points, or 4.46 percent, as of 11:02 a.m. The index rebounded after falling nearly 4 percent the previous session, with investors concerned about profitability from heavy investments in artificial intelligence (AI) infrastructure.

A buy-side sidecar is activated when the KOSPI 200 Futures Index rises 5 percent or more for at least one minute, triggering program trading for the KOSPI-listed shares.
