■ AI Data Centers and North American Grid Investment as Key Catalysts

Recently, wire and cable stocks have been driven by key catalysts including rising power demand from the expansion of AI data centers and investment in North American power grids. In fact, on the 18th, news of Gaon Cable expanding its cable production capacity in the United States came to the fore, sending related stocks including Gaon Cable, LS Eco Energy, Taihan Cable, and Iljin Electric higher in tandem during the session. In particular, stock-specific business momentum has continued.

■ Key Points to Watch After the Holiday

Market attention is turning to the first trading day after the Chuseok holiday. As wire and cable stocks showed differentiated movements by stock rather than moving in one direction together, the key point to watch after the holiday is how related issues such as power infrastructure, AI data centers, and North American businesses will affect share prices. In particular, attention is focused on whether LS Eco Energy and Iljin Electric, which closed higher on the day, will continue their upward trend, and whether Taihan Cable, Gaon Cable, and LS, which showed weakness, will turn the tide.
