KOSPI, 메타(Meta) 쇼크 딛고 8000선 탈환
After a near 8% plunge due to Meta’s AI overinvestment fears on the 2nd, the Korean stock market staged a dramatic V-shaped recovery on the 3rd, driven by massive institutional buying. A strong rebound in major chip stocks and a sharp 30-won drop in the KRW/USD exchange rate helped flip market sentiment, though the 11-day foreign selling streak remains a concern.

- Financial Stocks (Bank/Insurance) — +3~5% — Institutional defensive buying support
Top 3 Losers

Global Market Linkage Points
1. US Non-Farm Payrolls Below Expectations → Dollar Weakness
US employment weakness accelerated dollar depreciation, leading to the 30-won drop in the KRW/USD rate. Global rate cut expectations suggest a continued rebound in emerging market currencies.
2. Meta’s AI Cloud Entry → Sparks Global Chip Overcapacity Fears
Expanding data center operations by US Big Tech is interpreted as a signal of slowing demand for semiconductor chips, leading to a de-rating of the global chip sector. Guidance from companies like NVIDIA and AMD will be critical.
Tomorrow’s Checkpoints
- Monitor Early Morning Foreign Capital Flows: Check for signs of the 11-day net selling streak breaking.
- Reconfirm Semiconductor Technical Resistance (8,000 Support): A key factor for potential further KOSPI gains.
- Directionality Leading to Samsung Electronics Q2 Earnings (July 7): Check expectations against consensus.
Investor Action Items
- Prepare a Dip-Buying List: High volatility persists until supply/demand imbalances normalize. Review price targets and construct dollar-cost averaging strategies.
- Pre-check Semiconductor Earnings Consensus: Compare analyst EPS forecasts for Samsung Electronics to evaluate the potential for a positive earnings surprise.
- Utilize 24-Hour FX Market: Look for opportunities to react to nighttime dollar weakness or global events (especially stocks benefiting from export currency gains).
