Key Market Issues
1. KOSPI stuck in a 8,400-point trading range Today (the 30th), the KOSPI opened at 8,416.7 and briefly climbed to the 8,500s during early trading before ultimately closing in the 8,400s. Last week (June 22–26), the index fell 641.21 points (7.08%) to close at 8,411.21, with the Volatility Index (VKOSPI) hitting a record high of 95.09 on June 25.
2. Foreign investors sell 4 trillion KRW vs. institutional buying While the KOSPI dipped toward the 8,300 level due to a massive sell-off of over 4 trillion KRW by foreign investors, the KOSDAQ jumped 6–7%, triggering a sidecar as secondary battery and biotech stocks surged.
3. Major semiconductor investment news impacts the market News of large-scale investments by major domestic semiconductor firms boosted sentiment for U.S. equipment stocks, and the Philadelphia Semiconductor Index rose by more than 3%.
Trending Themes and Notable Stocks
1. Honam semiconductor cluster expectations drive construction stocks Construction stocks, including Kumho E&C and Namwha Civil Engineering, surged following government policies to create a semiconductor cluster in the Honam region. A total of 6 stocks on the KOSPI and 15 on the KOSDAQ hit the daily limit.
2. Soaring demand for beauty appliances due to weather shifts On the shopping platform 'Zigzag,' operated by Kakao Style, sales of skincare appliances skyrocketed by 200% from May 26 to June 23 compared to the previous month. Hair appliances like straighteners and dryers also saw an upward trend, driven by seasonal demand as temperatures rise.
3. Secondary battery and biotech stocks remain strong The KOSDAQ showed partial strength thanks to buying from foreigners and institutions, with secondary batteries and biotech leading the charge. Individual stocks like Samsung Biologics and LG Chem rose 7.07% and 10.52%, respectively, signaling positive momentum.
4. Concerns over KOSDAQ disclosure reliability Investor trust in KOSDAQ disclosures is eroding due to repeated instances where companies change their stance after announcing supply contracts or fundraising plans.
Macro Context
1. Record-high volatility signals market anxiety The VKOSPI reached an all-time high of 95.09 on June 25. This was attributed to heavy selling by foreign and institutional investors, with foreign investors reportedly dumping about 19 trillion KRW in assets last week.
2. Anticipation and anxiety ahead of semiconductor earnings season Following Micron's strong earnings, expectations for Samsung Electronics and SK Hynix’s Q2 results are growing. With semiconductor exports expected to increase by 55.7% compared to the same month last year, the upcoming earnings season is set to determine the direction of the KOSPI.
3. Hopes for a turning point in the July earnings season After a month of extreme volatility in June, there is hope that the KOSPI will show more stability in July as the earnings season kicks off.
