South Korea’s benchmark Kospi index fell more than 5% on Monday, marking its lowest level in nearly two months as investors questioned the sustainability of the artificial intelligence rally.

The broad-based selloff was concentrated in the technology sector, with memory chipmakers leading the decline amid growing concerns over demand durability and valuation levels.

The sharp drop follows a volatile week for the market, which saw the Kospi plummet as much as 8% on Thursday in what was the steepest single-day decline in the region’s AI-driven rally to date.

SK Hynix and Samsung Electronics were among the hardest hit, dragging down the index and triggering trading curbs on the exchange.

The continued selling pressure suggests that market participants are reassessing the near-term outlook for semiconductor stocks after a prolonged period of strength.

The selloff in Seoul mirrors broader weakness in global technology shares, with US tech stocks also facing headwinds.
