Global Background — Overnight U.S. Market

The U.S. stock market experienced a sharp drop overnight due to negative inflation indicators.

• Nasdaq & S&P 500: Both fell by about 2% as the September Consumer Price Index (CPI) was announced higher than expected, highlighting the possibility of a Fed rate hike (or prolonged high interest rates).
• Bond Yields: Short-term Treasury yields rose due to inflation data, acting as a valuation burden on growth and tech stocks.
• Memory Semiconductor Sector: U.S. memory-related stocks also showed simultaneous weakness due to the fallout from plunging semiconductor stock prices originating from South Korea and concerns over an AI bubble.

Leading Sectors & Themes

1. Semiconductors

• Movement: Large-cap semiconductor stocks like Samsung Electronics and SK Hynix plunged due to skepticism over the AI boom and concerns over intensified competition with China. This is the biggest cause of the KOSPI index decline.
• Leading Stocks: Weakness across the entire semiconductor value chain, including Samsung Electronics, SK Hynix, and Hanmi Semiconductor.
• Check Points: Foreign investors' net selling streak continues for 10 consecutive trading days, and the pace of exodus from semiconductor stocks in particular is determining the overall market trend.

2. Banks

• Movement: While earnings announcements from major U.S. banks showed mixed results, domestic bank stocks could show relative defense based on rate hike expectations (backed by strong U.S. CPI) and undervalued appeal.
• Leading Stocks: KB Financial Group, Shinhan Financial Group, Hana Financial Group, etc.
• Check Points: Attention must be paid to volatility according to U.S. bank earnings and the Fed's policy direction.

3. Secondary Batteries

• Movement: Amid the market-wide risk-off mood, these stocks are undergoing simultaneous adjustments as a high-valuation sector.
• Leading Stocks: LG Energy Solution, Samsung SDI, EcoPro BM, etc.
• Check Points: We need to check whether technical support lines are broken along with concerns over slowing global EV demand. (Specific daily fluctuation rate data is limited, but they showed high beta in the declining market.)

Watchlist Response Guide

This guide is reference information based on public news and market trends, and investment decisions are your own responsibility.

Samsung Electronics (005930)

• Today's Close / Fluctuation Rate: Closed weak based on the previous trading day (the 13th) (exact closing price data for the day requires real-time lookup). Excessive drop as a leading stock when KOSPI fell 5.46%.
• Supply and Demand: Massive foreign net selling continues, with institutions attempting some bargain hunting.
• Fundamental Triggers: Concerns over slowing AI semiconductor demand and memory price volatility. Despite announcing its largest quarterly operating profit in recent times, the stock showed a 'sell-on-news' pattern.
• Brokerage Target Price / Support & Resistance Lines: Although securities reports recently raised target prices (e.g., mentioning 170,000-won Samsung), the gap with the current stock price has widened. Need to observe whether it breaks the lower boundary of the recent 52-week trading range.
• Risk Factors: 1) Valuation pressure on growth stocks due to rate hike concerns triggered by U.S. CPI, 2) Intensified competition in Chinese semiconductors.
• Response Scenarios:
  • Favorable Flow: Potential rebound attempt if foreign net selling narrows and institutions switch to net buying.
  • Unfavorable Flow: High probability of further decline if technical support lines (e.g., 200-day moving average) are broken. Refrain from reckless averaging down.

SK Hynix (000660)

• Today's Close / Fluctuation Rate: Led the semiconductor sector decline alongside Samsung Electronics.
• Supply and Demand: Foreign selling pressure concentrated.
• Fundamental Triggers: While expectations for HBM (High Bandwidth Memory) demand remain valid, profit-taking is pouring in due to short-term overheating perceptions and AI bubble concerns. SK Securities and others suggested target prices up to 3 million won, but the current stock price is plunging.
• Brokerage Target Price / Support & Resistance Lines: Widening divergence between the current stock price and past target prices of 3 million won. Maintaining the psychological support level in the early 1-million-won range is crucial.
• Risk Factors: 1) Concerns over CAPEX (capital expenditure) cuts by U.S. Big Tech, 2) Outlook for falling memory prices.
• Response Scenarios:
  • Favorable Flow: Rapid rebound possible if positive news resurfaces after earnings announcements or if foreign buying turns around.
  • Unfavorable Flow: Need to aim for a technical rebound if it corrects 20-30% or more from its peak, but stay on the sidelines until a trend reversal is confirmed.

KB Financial Group (105560)

• Today's Close / Fluctuation Rate: Attention to whether it performs the role of a defensive stock amidst the declining market.
• Supply and Demand: Continued preference for dividend stocks by institutions and individuals.
• Fundamental Triggers: U.S. rate hike expectations (strong CPI) can be positive for improving bank net interest margin (NIM). However, domestic economic slowdown concerns act as a risk for loan defaults.
• Brokerage Target Price / Support & Resistance Lines: Downside rigidity exists due to dividend yield attractiveness. Need to check whether recent quarterly earnings meet consensus.
• Risk Factors: 1) Issue of additional provisioning related to real estate PF (project financing), 2) Strengthening of household debt regulations.
• Response Scenarios:
  • Favorable Flow: Relative strength as a safe-haven asset during market instability.
  • Unfavorable Flow: Potential simultaneous weakness if regulatory risks across financial stocks are highlighted.

Events to Watch Tomorrow

1. Follow-up Reaction to U.S. CPI Data: Additional market interpretations of the already announced September CPI and statements from Fed officials.
2. Bank of Korea Rate Decision Schedule: Formation of prior expectations for the Bank of Korea's base rate decision scheduled for next week.
3. Domestic Corporate Earnings Season: Updates on Q3 earnings guidance from major companies.
4. Foreign Supply and Demand Trends: Volatility in the KRW/USD exchange rate in the Seoul foreign exchange market and whether foreign stock net buying/selling switches.

One-Line Strategy Memo

"CPI shock and semiconductor adjustment: raise cash weighting and approach with defensive stocks." Tomorrow's market, reflecting interest rate hike concerns driven by tonight's strong U.S. CPI, will be dominated by a 'risk-off' mode. To prepare for the possibility of a further decline in the semiconductor sector, consider portfolio hedging and maintain a heavier weighting in defensive stocks such as dividend stocks or consumer staples rather than oversold blue chips.

Terms & References

• Risk-off: A phenomenon where funds flow out of risky assets like stocks and move to safe assets like bonds or cash due to increased uncertainty.
• Box-range Breakout: When a stock price that formed a specific price range (upper and lower bounds) breaks out of that range and moves sharply.
