Record-Breaking Sidecar Triggered as Both Markets Rebound Sharply... KOSPI Closes at 5,478

Record-Breaking Institutional Net Buying
Institutions Purchase 4.3 Trillion Won in KOSPI Alone

On April 1, both the KOSPI and KOSDAQ markets rebounded strongly, with a buy-side sidecar (temporary suspension of program buy orders) activated on both exchanges. This is interpreted as being influenced by the rebound in the U.S. stock market overnight, driven by expectations of an end to the war.

On this day, the KOSPI closed at 5,478.70, up 8.44% from the previous day. The index surged more than 5% at the opening and the buy-side sidecar was triggered at 9:00 a.m. The upward trend continued steadily, drawing an upward curve throughout the session.

Institutional buying drove the index higher. Institutional investors posted a net purchase of 4.3162 trillion won on this day alone, marking the highest single-day net buying volume this year. In contrast, foreign investors and individuals recorded net sales of 420.9 billion won and 4.37 trillion won, respectively.

All sectors rose except for the entertainment and culture sector, which fell by 1.02%. The construction (12.18%) and electrical and electronics (11.36%) sectors showed particularly sharp gains. Many sectors also rose more than 5%, including manufacturing (9.62%), metals (8.85%), machinery and equipment (8.36%), securities (7.61%), and transportation equipment and parts (6.86%).

All of the top 10 stocks by market capitalization gained. Both Samsung Electronics (12.5%) and SK Hynix (10.4%), the top two by market cap, posted double-digit increases. Other notable gainers rising more than 5% included Hyundai Motor (9.3%), Doosan Enerbility (8.0%), SK Square (7.1%), Kia (6.6%), and Hanwha Aerospace (5.8%).

The KOSDAQ also closed sharply higher, ending the session at 1,116.18, up 6.06% from the previous day. The index opened at 1,090.36, up 3.61%, and maintained its upward momentum.

In the KOSDAQ market, simultaneous net buying by foreign investors and institutions pushed the index higher. Their net purchases amounted to 522.2 billion won and 485.3 billion won, respectively. Individual investors recorded a net sale of 1.0212 trillion won.

All sectors recorded gains. The largest increases were in electrical and electronics (8.67%), machinery and equipment (8.48%), transportation equipment and parts (6.66%), financial (6.63%), distribution (6.55%), manufacturing (6.30%), general services (5.92%), chemicals (5.66%), and metals (5.37%).

Major gainers included LIG Nex1 (9.7%), ABL Bio (8.3%), Rainbow Robotics (7.2%), Ecopro (7.1%), Legochem Biosciences (6.7%), Alteogen (5.4%), and HLB (5.3%).
