KOSPI Hits New Yearly High at 3116.72 After Passage of Commercial Act Amendment

On July 3, the KOSPI rose more than 1% and set a new yearly high, buoyed by the passage of the Commercial Act amendment.

The KOSPI index closed at 3116.27, up 41.21 points (1.34%) from the previous trading day, marking a new yearly high. The previous high for the year was 3108.25, recorded on June 25.

The index opened at 3100.33, up 25.27 points (0.82%) from the previous session, and expanded its intraday gains due to net buying by both foreign investors and institutions. Foreign investors recorded net purchases of 629.5 billion won, while institutions net bought 561.1 billion won. In contrast, individual investors net sold 1.327 trillion won.

The rise in the KOSPI was led by Samsung Electronics and secondary battery-related stocks, which had previously taken a breather. Samsung Electronics rose 4.93% on the day, while LG Energy Solution climbed 5.29%, driven by a rebound in Tesla.

Most of the top market capitalization stocks also rose. Samsung Biologics gained 3.47%, KB Financial Group 3%, Hyundai Motor 0.47%, NAVER 0.40%, and Kia 0.10%.

Analysts noted that the passage of the Commercial Act amendment in the plenary session, as well as remarks by President Lee Jaemyung in a press conference once again emphasizing a "money move" into equities, drove strong institutional buying.

In a press conference marking his first month in office, President Lee stated, "We will prepare for the KOSPI 5000 era by advancing the capital market, which is the core platform for growth, so that technology-driven growth can gain strong momentum," and added, "We will spare no effort to ensure that funds in the market flow from unproductive to productive sectors, so that a virtuous cycle in the economy can be restored."

The KOSDAQ index closed at 793.33, up 11.16 points (1.43%) from the previous session.

Among the top KOSDAQ market cap stocks, most posted gains, with Pharmaresearch up 6.28%, Ligachem Bio 5.84%, Ecopro 5.37%, Peptron 4.85%, Lino Industrial 4.67%, and Kolon TissueGene 4.03% showing particularly strong increases.

In the Seoul foreign exchange market, the dollar-won exchange rate ended weekly trading at 1,359.40 won, up 0.70 won.

Lee Woongchan, a researcher at iM Securities, analyzed, "As the domestic stock market approaches the 3,100 level, the momentum for policy-related stocks and the strength of the index's rise have somewhat weakened," and added, "Institutional investors are now giving considerable thought to their future portfolio strategies."

He further stated, "Policy momentum is likely to slow following the passage of the Commercial Act amendment," and recommended a benchmark-neutral strategy for Samsung Electronics, IT hardware, and automobiles, which have not risen this year, ahead of earnings announcements and trade negotiations.
