Top 5 Key News Items
KRW/USD hits 1,520; highest since the financial crisis
- What happened?: The won-dollar exchange rate exceeded an average of 1,520 in June, marking its highest level in 28 years since the 1997 Asian financial crisis. This is about 70 won higher than during the 2008 financial crisis, driven by a combination of the U.S. Federal Reserve's tightening, geopolitical risks in the Middle East, and capital outflows by foreign investors.
- Market Impact: While a weaker won is positive for the earnings of export-oriented companies, it increases the burden of living costs for citizens due to rising import prices. It acts as a boon for the tourism industry, as it makes Korea more affordable for overseas travelers.
"Only Samsung and Hynix are holding up": 8 out of 10 KOSPI stocks are down
- What happened?: Although the KOSPI broke through the 9,000-point mark for the first time in history, eight out of ten stocks have actually fallen this month. Excluding Samsung Electronics and SK Hynix, the KOSPI index is lower than it was at the beginning of the month.
- Market Impact: Deepening polarization is eroding the profitability of retail investors. With capital concentrated in large-cap semiconductor stocks, funds are not being distributed to small and medium-sized or growth stocks, narrowing investment opportunities.
17.5%p gap between KOSPI and KOSDAQ: "World-leading vs. laggard"
- What happened?: While the KOSPI posted the highest weekly return among major global stock markets last week, the KOSDAQ saw a sharp decline, pushing domestic market polarization to the extreme. The performance gap between the two markets has reached 17.5%p.
- Market Impact: The slump in the KOSDAQ is cooling investor sentiment toward venture, bio, and growth-stage companies, as institutions and foreign investors concentrate their funds on KOSPI large-caps.
Semiconductor supply chain stocks dominate KOSDAQ top 20; poised to overtake bio
- What happened?: Representative companies in semiconductor front-end and back-end processes have seen triple-digit growth this year, entering the top 20 list of KOSDAQ market caps in droves. Jusung Engineering took the top spot with a 597% increase, and the number of semiconductor-related stocks in the top 20 increased from four at the beginning of the year to ten. Conversely, the number of bio stocks has shrunk from 12 to 7.
- Market Impact: Strength in stocks benefiting from the semiconductor super-cycle, though the KOSDAQ is losing sector diversity due to the declining appeal of bio investments.
Domestic equity ETFs smile at KOSPI surge; net assets exceed 263 trillion won
- What happened?: Driven by the KOSPI's rise, the net assets of domestic equity ETFs have hit 263.5401 trillion won. This is a roughly 6.5-fold increase from the 40 trillion won level in December 2024, with domestic equity ETFs now accounting for more than 50% of the domestic ETF market.
- Market Impact: Improved supply and demand for large-cap stocks due to the inflow of small retail investors, though there are concerns regarding increased market volatility due to excessive concentration.
Leading Sectors & Themes
Semiconductors (Memory/Non-memory equipment, materials, parts)
- Trend: Rising. Benefiting from AI demand and the recovery of memory chip prices. Strength in Samsung Electronics and SK Hynix is leading the market, lifting semiconductor equipment and material companies.
- Key Stocks: Samsung Electronics (Leading the rise), SK Hynix (Driving recovery), Jusung Engineering (+597% YTD)
Bio/Pharma
- Trend: Falling. Relatively weak due to concentration in semiconductors and AI. Despite large-scale technology exports, share prices remain weak.
- Key Stocks: Many KOSDAQ bio companies are weak; bio share in the KOSDAQ top 20 is trending downward.
Export stocks benefiting from exchange rates
- Trend: Rising. Expectations for improved earnings for export companies due to the weak won. However, net profit gains are limited due to rising raw material import costs.
- Key Stocks: Large firms in automotive, chemical, and electronics.
Overseas Market Connection Points
Fed's tightening stance
The U.S. Federal Reserve's tightening signal is fueling the "strong dollar" trend, deepening the weakness of the won and putting pressure on foreign capital to pull out of the Korean stock market.
Persistent geopolitical risk in the Middle East
Despite the U.S.-Iran ceasefire agreement, the market is waiting to confirm specific terms. Uncertainty is causing continued volatility in oil prices and exchange rates.
Tomorrow's Checkpoints
- Foreign investor flow signals — Watch for continued sell-offs while the exchange rate remains stuck in the 1,520 range.
- FOMC results and comments from new Chair Powell — The new Fed chair's take on interest rate direction will lead to a re-evaluation of exchange rates and the dollar.
- Supply and demand for stocks beyond SK Hynix and Samsung — Assess whether mid-cap and supply chain companies can sustain their gains.
Investor Action Items
- Review risks of 1,520 KRW/USD fixation — Screen for companies burdened by rising technology import costs if the rate rises further.
- Check profit-taking timing for semiconductor supply chain leaders — Examine the overheating levels of stocks like Jusung Engineering, which has risen over 600%.
- Explore bargain hunting for KOSDAQ bio stocks — Look for potential valuation re-evaluations following the recent significant slump.
