Samsung Electronics (005930)
- Closing Price / Change: 277,500 KRW (-6.25%)
- Market Flow: Shift to net selling by foreigners; institutional range-bound trading.
- Fundamental Triggers:
- Outlook for prolonged memory shortages due to increased AI investment vs. concerns over slowing profit growth in H2.
- Concerns over limited memory price increases (limited average selling price growth in initial LTA stages).

- Risks:
- Global IT investment contraction scenario due to renewed Fed rate hike concerns.
- ASP decline risk due to deepening concerns over memory chip oversupply.
- Strategy:
- Positive: Monitor for a low-point buy opportunity above 270,000 KRW if memory price hikes are reaffirmed.
- Negative: If it drops below 240,000 KRW, consider it a signal for further adjustment; track support at 260,000 KRW.

Quick Strategy Note
A sharp reversal after a record rally is a sign of overheating. The "plunge-spike-plunge" pattern from foreigners is maximizing KOSPI volatility. Focus on ① Support levels for Samsung/SK Hynix, ② U.S. 10-year Treasury yields, and ③ the sustainability of KOSDAQ AI/Robot themes. In a short-term risk-off mode, look for bargain opportunities, but be ready to shift to a defensive position if there is an additional 5%+ drop. Prepare for risks down to the 6,000–6,200 KOSPI level while wisely taking profits on robotics and AI themes.
