On the 29th, the KOSPI broke through the 4,200 level intraday. As buying concentrated in semiconductor stocks led by Samsung Electronics and SK hynix, the index topped 4,200 for the first time in 38 trading days.
The KOSDAQ is also rising intraday as funds flow into growth stocks such as Robotics and biotech.
As of 2:07 p.m., the KOSPI was trading at 4,204.58, up 74.9 points (1.81%) from the previous trading day. Starting the day at 4,146.48 won, the KOSPI has been widening its intraday gains as retail investors and foreigners net bought 161.1 billion won and 131.5 billion won, respectively.
SK hynix, which had its investment warning lifted on the day, led the index higher with gains in the 5% range. In the securities industry, brokerages are raising target prices for semiconductor stocks one after another, citing a sharp rise in legacy chip prices such as DRAM and NAND, HBM4, which is expected to go into full mass production in 2026, and HBM3E, whose price is rising faster than expected.
Hanwha Aerospace also jumped more than 8%. Lee Jae-won of Shinhan Investment & Securities said, "With the multiple rocket launcher 'Cheonmu' signing a 5.8 trillion won export contract with Poland on the day, buying has spread across industrials such as defense, shipbuilding, machinery, and nuclear power, which had been sidelined in the recent seesaw between semiconductors and biotech."
At the same time, the KOSDAQ was trading at 931.07, up 11.4 points (1.24%) from the previous trading day. Starting the day at 923.22, the KOSDAQ has been widening its intraday gains.
