KOSPI / KOSDAQ Overview

The KOSPI breached the 7,500 level intraday on May 7 before closing at 7,490.05, marking a new all-time high. Middle East ceasefire optimism and a semiconductor rally led by Samsung Electronics and SK Hynix powered the surge. It's a dramatic rebound — just two months after Middle East conflict fears pushed the KOSPI down to 5,000, the index has now smashed through 7,000 and touched 7,500. In contrast, KOSDAQ fell 0.91% to close at 1,199.18, showing that smaller-cap stocks were left out of this large-cap driven rally.

Supply & Demand Flow

• Foreigners: Despite record net selling of over 7 trillion won on May 7, KOSPI maintained its uptrend as domestic institutions and retail investors absorbed the selling pressure
• Institutions: Net buying to defend the market
• Retail: Net buying to absorb foreign selling

Today's Leading Sectors & Stocks (minimum 3)

• Samsung Electronics: Core leader of this rally — benefiting from renewed semiconductor supercycle expectations and global AI investment tailwinds; reports even emerged that it has overtaken Berkshire Hathaway in market cap
• SK Hynix: Rising in lockstep with semiconductor sector strength — bolstered by expanding AI demand and sustained HBM supply momentum
• KOSDAQ Biotech: Renewed controversy over Alteogen's proposed KOSPI listing dampened sentiment across KOSDAQ, contributing to weakness in the overall KOSDAQ index

🇺🇸 US Markets

Three Major Indices (May 6–7 Recent Sessions)

On May 6 (Wednesday), US stocks surged as AMD posted strong earnings and news of US-Iran peace talk progress converged. The S&P 500 crossed 7,300 for the first time in closing history, and the Nasdaq marked a second consecutive all-time closing high. Following AMD's earnings announcement, chipmakers and AI-related stocks surged across the board, with the technology sector leading broadly. The Dow Jones also climbed over 600 points in synchronized strength. On May 7 (Thursday), semiconductor consolidation following the previous days' sharp gains and Norway's central bank rate hike tempered gains, though geopolitical uncertainty resurfaced as Iran claimed ceasefire accord violations.

Key Movers Today (minimum 3)

• AMD (AMD): Strong quarterly earnings beat — robust AI chip demand drove a sharp stock rally, triggering broad-based gains across semiconductor and AI names
• Big Tech Overall: Core driver of consecutive S&P 500 and Nasdaq all-time highs — AI infrastructure investment momentum continues
• Energy Sector: Peace talks expectations sparked crude oil selloff → energy stocks weakened, but the market viewed this as a positive inflation-relief signal overall

Sector Trends Technology and semiconductor sectors maintained strength on AI investment tailwinds and AMD's solid earnings. Energy stocks weakened on crude's sharp decline (from Middle East peace optimism). On May 7, semiconductors entered consolidation after their recent spike, causing tech stocks to turn mixed.

🌏 Asian & European Markets

Asia (Japan, China, Hong Kong)

Asian markets held broadly firm on May 7. Hong Kong's Hang Seng rose 1.47%, and China's CSI 300 climbed 0.38%. South Korea's KOSPI continued its historic run, surpassing 7,500 shortly after breaking past 7,000 the previous day. KOSDAQ fell 0.91%, however, showing clear evidence that smaller-cap stocks lagged the large-cap rally. Middle East peace talk progress and global AI and semiconductor momentum supported a risk-on flow across Asia.

Europe (UK, Germany, France)

European markets saw gains capped on May 7 as Iran's ceasefire violation claims and Norway's central bank rate hike announcement weighed. With Middle East peace hopes persisting, geopolitical uncertainty resurfaced, keeping investment sentiment cautious.

📊 Today's Market Drivers

• US-Iran Ceasefire Optimism: Reports of the US and Iran approaching a peace accord sparked strong risk-on sentiment across global equities. Crude prices collapsed, which markets interpreted as inflation relief. However, on May 7, Iran's claims that the US and regional allies violated the ceasefire accord brought geopolitical uncertainty back into focus.

• AMD Earnings & AI Semiconductor Momentum: AMD's strong quarterly results triggered a broad rally in chipmakers and AI stocks. Expectations of expanded AI infrastructure investment drove Nasdaq and S&P 500 to new all-time highs, while Samsung Electronics and SK Hynix surged in lockstep in South Korea.

• KOSPI All-Time High & Foreign Investor Record Selling Coexist: The KOSPI hit a historic intraday 7,500 level while foreigners executed record net selling exceeding 7 trillion won. The fact that domestic institutions and retail absorbed this selling and supported the index offers a key gauge of domestic buying power's staying power.

• Semiconductor Consolidation & Profit-Taking: On May 7, profit-taking emerged after several days of sharp gains in semiconductors, temporarily cooling upside momentum. Sloup Report noted: "After a dazzling mid-session rally, stocks have flattened, and even amid peace talks hopes, oil and rates have retreated together."

🔭 What to Watch Next

Key Events This Week

• US-Iran Peace Talks Progress: Market moves in crude, defense stocks, and risk-on sentiment hinge on a deal. Watch for any word on talks resuming after Iran's violation claims
• Federal Reserve Policy Direction: Monitor Fed Chair succession news and shifting rate-cut expectations before Powell's term ends
• Big Tech Earnings Season Wind-Down: Additional earnings reports after AMD will signal whether AI investment momentum sustains
• KOSPI 7,500 Sustainability: Crucial to confirm whether domestic demand can support further gains amid massive foreign selling
• KOSDAQ Underperformance: Continued focus on KOSDAQ-specific issues like Alteogen's KOSPI listing dispute and their market impact

Investor Checklist

• Reconfirm Middle East peace deal odds and crude oil directional bias
• Determine if foreign capital's record selling is structural exit or short-term profit-taking
• Assess whether AI and semiconductor rally is overheating and whether earnings momentum will persist

💬 Key Insight

Middle East peace hopes and AI momentum created simultaneous historic milestones — KOSPI 7,500 and S&P 7,300 — yet record foreign selling and semiconductor profit-taking warn that fresh catalysts are needed to sustain the advance.
