Supply and Demand Trends (KOSPI Market)

Foreigners and institutions dominated today's session, pushing the index higher. While foreigners net-sold 693 billion won and retail investors net-sold 488.7 billion won yesterday (the 9th), the mood completely reversed today.

• Foreign Investors: Shifted to net buying (specific figures not mentioned in the article, but reported as 'net buyers') — inflows centered on large semiconductor stocks like Samsung Electronics and SK Hynix.
• Institutional Investors: Maintained net buying (continuing the momentum from yesterday's 720.4 billion won net purchase).
• Retail Investors: Continued selling dominance, prompting expressions like "only retail investors are selling."

Top 5 Key News Today

1. Kospi surges over 4% on soaring U.S. semiconductor stocks

• What happened?: Following a 6.86% surge in the U.S. semiconductor index overnight, the domestic stock market was impacted, closing the Kospi up 4.39% at 5,239.13. This broke a three-day losing streak, rebounding after four sessions.
• Market Impact: Flagship semiconductor stocks such as Samsung Electronics (+4.74%) and SK Hynix (+6.69%) drove the index gains.

2. KRW/USD exchange rate falls after four days

• What happened?: As of the 3:30 PM daytime closing price, the KRW/USD exchange rate dropped 9.6 won from the previous day to 1,337.5 won. This was analyzed as export companies cashing in dollars (selling dollars) due to perceptions of a peak.
• Market Impact: Exchange rate stability increased foreign investors' expectations of currency gains, positively impacting capital inflows into the domestic stock market.

3. Simultaneous buy sidecars triggered for Kospi and Kosdaq

• What happened?: Buy sidecars were triggered for the Kospi at 9:06 AM and the Kosdaq at 9:10 AM, right after the market opened. This mechanism is triggered when a 10%+ rise from the previous day is sustained for one minute, signaling a dramatic improvement in investment sentiment.
• Market Impact: Buying pressure spread across semiconductors, secondary batteries, and robot themes, causing total market trading value to surge.

4. Spread of perception that "semiconductor crash was excessive"

• What happened?: Brokerages such as SK Securities analyzed that "the Kospi was already in an extreme situation," making forecasts dominant that even a small catalyst could trigger a widespread recovery.
• Market Impact: As excessive concerns were washed away, valuation appeal stood out, causing semiconductor and data center (DC) related stocks to surge.

5. Partial relief over U.S. midterm election 'blue tsunami' concerns

• What happened?: Recent downward pressure caused by data center delay concerns stemming from U.S. midterm election results partially eased alongside the rebound in the U.S. stock market.
• Market Impact: AI infrastructure and data center-related stocks showed strong retracement of their previous steep drops.

• Auto Stocks: Weak yesterday (the 9th) — joined today's rebound, but relative strength remains uncertain.

Overseas Market Linkage Points

1. U.S. Semiconductor Sector Strength: Major U.S. semiconductor stocks like AMD (+11%), Intel (+7.7%), and TSMC ADR (+6.3%) surged, acting as a trigger for Korean semiconductor stocks.
2. Falling Global Oil Prices: Lower oil prices alleviated inflation concerns and stimulated global risk-on sentiment, contributing to the rise in the Korean stock market.

Tomorrow's Checkpoints

1. Sustainability of Foreign Supply and Demand: Need to check whether foreigners, who returned to net buyers in just a day, will continue additional purchases.
2. Impact of U.S. CPI/PPI Releases: Assess the impact of this week's scheduled U.S. Consumer Price Index (CPI) and Producer Price Index (PPI) releases on the rate path.
3. Whether Exchange Rate Settles in 1,340 Won Range: Monitor potential foreign capital outflows if the exchange rate turns upward again.

Investor Action Items

• Re-evaluate Semiconductor Earnings Consensus: Valuation burdens have increased following the sharp rise, so check for surprises relative to consensus during upcoming earnings announcements.
• Consider Short-Term Profit-Taking Strategies: A ~4% surge may carry the character of a technical rebound, so locking in profits in short-term gains or risk management is necessary.
• Hedge Exchange Rate Volatility: Since the exchange rate has dropped to the 1,330 won range, portfolios heavily weighted toward exporters should review hedging strategies against potential exchange rate hikes.
