KOSPI / KOSDAQ Summary

The KOSPI reached a historic milestone on May 7, surpassing the 7,500 mark for the first time ever in early trading. On the previous trading day (May 6), the KOSPI closed at 7,384.56, up 6.4%, with an intraday high of 7,426.60. This surge was primarily fueled by a 15% jump in Samsung Electronics, driven by high expectations for semiconductor and AI infrastructure investment. However, as foreign investors turned to a net sell-off of ₩6 trillion during the May 7 session, the index showed high volatility near the breakeven point. This massive profit-taking comes just a day after foreigners net-bought ₩3.1 trillion, effectively capping the index's upward momentum.

Flow Trends (May 7 Intraday)

• Foreigners: ~₩6 trillion net sell-off (a sharp reversal from the previous day's ₩3.1 trillion net buy)
• Institutions: Expected to shift to net buying (final figures unconfirmed)
• Individuals: Estimated to be buying on the dip (final figures unconfirmed)

Today's Leading Sectors & Stocks

🇺🇸 U.S. Market

Three Major Indices (As of May 6)

U.S. markets hit new highs on Tuesday, May 6, as the S&P 500 broke through the 7,300 mark for the first time. The Nasdaq rose about 2%, and the Dow Jones surged over 600 points. The rally was driven by widespread reports that the U.S. and Iran are nearing a deal to end the conflict, significantly boosting investor sentiment. AI-related tech stocks led the rally, while falling international oil prices also acted as a tailwind.

Key Daily Moves (May 5–6)

• Tech Stocks (General): Strong — Benefiting from the double tailwinds of Iran ceasefire hopes and sustained AI infrastructure investment.
• Energy Stocks: Mixed — Faced profit-taking pressure due to falling oil prices, though still participated in the overall market rise.
• Russell 2000 (Small-cap Index): New high — Symbolizes the spread of risk-on sentiment.

Sector Trends

The tech and AI sectors showed overwhelming strength, while consumer goods, airlines, and transportation stocks also rebounded on expectations of reduced energy costs. Conversely, energy producers saw relative weakness, taking a direct hit from the drop in oil prices.

🌏 Asian & European Markets

Asia (Japan, China, Hong Kong)

Asian-Pacific markets rose broadly on May 7, digesting hopes for easing tensions in the Middle East. CNBC reported that Asian markets rebounded despite the resurgence of Middle Eastern tensions. The Hong Kong Hang Seng Index participated in the upward trend, while the KOSPI drew significant attention with its historic 7,500 milestone. Japan’s Nikkei 225 followed the upward trend led by the AI and semiconductor sectors.

Europe (UK, Germany, France)

European markets remained strong amid hopes for an Iran ceasefire and falling international oil prices. According to the Reuters Morning Brief, the surge in the Seoul market (Samsung Electronics surpassing Berkshire Hathaway) sent a positive signal to global investor sentiment, with major European indices following suit.

📊 Market Drivers Today

• Iran Ceasefire Negotiation Hopes: Global markets surged in unison as reports surfaced that the U.S. and Iran are close to a peace agreement. President Trump's declaration to suspend operations in the Strait of Hormuz has eased concerns over crude oil supply, and the resulting drop in oil prices has fueled expectations of lower corporate costs. This issue was a critical factor in the KOSPI crossing the 7,500 mark.

• Expansion of AI/Semiconductor Infrastructure Investment: Large-scale AI infrastructure investment announcements by U.S. Big Tech firms are driving explosive demand for semiconductors. Samsung Electronics (+15%), SK Hynix (market cap over ₩1,000 trillion), and U.S. tech stocks in general are leading the global market rally as key AI beneficiaries.

• Robust Corporate Earnings Season: Many large corporations reported earnings exceeding expectations, instilling confidence in the market. CNBC reported that a combination of solid earnings and falling oil prices helped push the S&P 500 above 7,300 for the first time.

• Foreigner Profit-Taking Risk: In the case of the KOSPI, foreign investors—who had net-bought ₩3.1 trillion the previous day—reversed to a ₩6 trillion net sell-off in a single day, significantly increasing index volatility. This profit-taking on short-term gains is acting as a hurdle for further growth.

🔭 Future Watchlist

Key Events This Week

💬 One-Line Insight

The KOSPI touched the historic 7,500 mark, but the foreign investors' ₩6 trillion reversal in just one day serves as a cold market warning that "the good news is already priced in."
