🇰🇷 South Korean Market
KOSPI / KOSDAQ Overview
On May 12, the KOSPI closed at 7,643.15 under heavy foreign selling pressure, dropping over 2% from the previous day’s record high of 7,822.24. Despite a morning start supported by institutional and retail buying, the market turned sharply lower in the afternoon due to the inflation shock from New York and geopolitical risks involving Iran. Behind the KOSPI's rally, more than 30% of listed stocks have seen declines this year, highlighting a polarization where gains are concentrated in AI semiconductor leaders like Samsung Electronics and SK Hynix. Meanwhile, according to the Seoul Economic Daily on May 13, despite foreigners net-selling over 20 trillion won in the KOSPI over the past four trading days, the trend of overseas capital inflow into Korean stocks continues due to easier access via new integrated accounts.

- Foreigners: Net-sold approx. -5 trillion won (KOSPI)
- Institutions: Net-bought in the morning → Turned to selling in the afternoon
- Individuals: Supported net-buying early in the session
Leading Sectors & Stocks Today

- Samsung Electronics: Strong, with buying interest focused on AI semiconductors alongside SK Hynix, leading index gains.
- KOSDAQ vs. KOSPI Gap: The KOSDAQ continues to underperform the KOSPI as AI mega-caps dominate market sentiment, leaving small and mid-cap KOSDAQ stocks behind.
🇺🇸 U.S. Market
Major Indices (May 12)
U.S. markets closed mixed on May 12 following the release of April CPI data that exceeded expectations. The S&P 500 and Nasdaq fell as tech stocks weakened under inflation pressure, while the Dow Jones rose slightly. After the S&P 500 crossed the 7,400 mark for the first time on May 11, the market took a breather. Concerns over the collapse of Iran peace talks and rising oil prices also weighed on investor sentiment. Nasdaq and the Russell 2000 showed some recovery from the initial inflation and oil price shocks.
Key Movements Today
- Tech Stocks (including semiconductors): A pause in the chip rally following yesterday's surge as profit-taking emerged.
- Dow Jones Components: Led slight gains, with relative strength in defensive and value stocks.
- Oil-related Stocks: Oil prices rose due to Iran risks, providing relative strength to the energy sector.
Sector Trends
As hot CPI data pushed back expectations for additional Federal Reserve rate cuts, rate-sensitive growth stocks (tech, semiconductors) weakened. The energy sector maintained relative strength due to rising oil prices driven by geopolitical risks in Iran, while defensive sectors (healthcare, utilities) showed mixed results.
🌏 Asia & Europe Markets
Asia (Japan, China, Hong Kong)
On May 12, the Hong Kong Hang Seng fluctuated around -0.16% in late afternoon trading, while the China CSI 300 fell slightly to 4,948.05 (-0.08%). On May 13, Asian markets turned higher as AI optimism outweighed concerns over Iran and inflation. On May 11, the KOSPI had surged 4.32% to a record high of 7,822.24 on the back of AI semiconductor momentum, with SK Hynix jumping over 11%.
Europe (U.K., Germany, France)
In pre-market futures on May 13, European indices tracked Asia's rebound, with the pan-European index up +0.9%, German DAX +0.8%, and U.K. FTSE +0.6%. Despite the mixed U.S. close and CPI shock, European markets saw buying interest driven by AI momentum and expectations for strong corporate earnings.
📊 Market Drivers
-
U.S. April CPI Shock: The actual figure came in higher than the +3.7% year-over-year estimate from economists polled by Dow Jones, cooling Fed rate cut expectations. This hit growth and tech stocks directly, putting the brakes on the S&P 500 and Nasdaq’s record-breaking rally.
-
Iran Geopolitical Risk: President Trump rejected Iran's latest peace proposal as "unacceptable," fueling concerns that the U.S.-Iran truce is hanging by a thread. While energy stocks benefited from rising oil prices, it triggered overall risk-off sentiment.
-
AI Semiconductor Momentum vs. Foreign Profit-Taking: The KOSPI broke 7,800 led by the AI rally, but the 20 trillion won in foreign net-selling over the past four days triggered the May 12 slide. Tension persists between the "KOSPI 10,000" outlook and foreign exit pressure.
-
May 13 AI Rebound: On May 13, Asian markets successfully rebounded, shaking off inflation and Iran concerns thanks to strong AI-related sentiment. European futures followed, reflecting market confidence in the enduring global AI theme.
🔭 Watchlist
Key Events This Week
- Additional U.S. Inflation Indicators: PPI (Producer Price Index) and retail sales data — further verification needed following the CPI shock.
- U.S.-Iran Negotiations: Whether talks resume after Trump's "unacceptable" remark — direct impact on oil and energy sectors.
- Fed Commentary: Monitoring statements from Fed officials regarding rate outlooks after the hot CPI — potential for recalibrating the timing of rate cuts.
- KOSPI Foreign Flows: Watching whether the foreign sell-off continues after 20 trillion won in net-selling over four days, or if inflows through integrated accounts provide support.
- SK Hynix & Samsung Electronics News: Earnings and order updates remain the key variables for AI momentum.
Investor Checklist
- Inflation-driven delay in rate cut expectations → Review exposure to interest-rate-sensitive growth stocks (tech, biotech).
- Deepening concentration in KOSPI AI mega-caps → Manage risks related to the gap between these leaders and KOSDAQ/small-cap stocks.
- Increased oil price volatility due to Iran risks → Consider energy sector hedging and portfolio defense strategies.
💬 One-Line Insight
While the "all-time high fatigue" has arrived due to hot inflation and Iran risks, AI momentum remains the global market's only savior—but the 20 trillion won in foreign selling on the KOSPI is a warning siren signaling "cracks in the rally."
