Han Ji-young, a researcher at Kiwoom Securities, stated, "Today, the domestic market is expected to open higher due to the anticipated ceasefire between the U.S. and Iran, which has led to a drop in oil prices, and the rally in U.S. semiconductor stocks. In the early trading session, we may see strong performance in semiconductor stocks, followed by a positive cycle in other sectors."
 
The researcher added, "We are currently witnessing profit momentum centered around AI and semiconductor stocks. It is advisable to increase stock allocations and focus on leading stocks in the existing AI value chain, such as semiconductors and MLCCs, at least until the second quarter earnings season."
