Weekly Trends and Themes
1. US Market Performance
S&P 500: +0.50% | Nasdaq: +0.61% | Dow: -0.79%
The S&P 500 advanced +0.50% for the week, with Nasdaq outperforming at +0.61%. Gains were concentrated in growth/tech; defensive sectors lagged.
Magnificent 7: 4 of 7 Mag7 stocks advanced. Best: Meta (+11.48%), worst: Tesla (-2.86%).
Takeaway: Consolidation week — no tactical change needed.
2. Korean Market Performance
KOSPI: -7.15% | KOSDAQ: -1.14% (weekly)
KOSPI fell -7.15% — a significant weekly decline; avoid new entries until price stabilizes.
KOSDAQ modestly lower (-1.14%), outperforming KOSPI — risk appetite favoring small/mid caps.
Among Korean blue chips: SK Hynix led (-6.96%), Samsung lagged (-10.38%).
Takeaway: Weak week — wait for stabilization before new entries.
3. Currency Impact (KRW/USD)
Weekly KRW Move: -1.91% ₩1,529 → ₩1,500
The won strengthened notably (-1.91%, ₩1,529 → ₩1,500) — a tailwind for USD investors; currency appreciation boosts USD-basis returns from Korean equities.
Investor Implication: Positive for USD investors — total return (price + FX) exceeds the index gain.
Export sector note: KRW strength compresses USD-reported revenues for Korean exporters — margin headwind for next quarter.
4. Treasury Yields
10Y: 4.49% → 4.54% (+5 bps)
The 10Y Treasury yield held steady at ~4.54% (+5 bps for the week) — no yield-driven repricing of equities.
Market Implication: Stable rates support growth stock multiples.
5. Key Weekly Observation
- US outperformed Korea by 7.7pp this week — US macro strength or global risk rotation toward dollar assets is the likely driver.
- Wide Mag7 dispersion this week (14.3pp between best and worst) — stock-pickers’ market; index-level moves understate individual name volatility.
Best and Worst Performers
Best (Weekly Upside Movers):
- Meta: +11.48% ████████████████████
- NVIDIA: +7.88% ███████████████

Commentary:
Meta was the standout winner at +11.48% — a weekly gain of this size reflects either strong earnings catalysts, analyst upgrades, or a short-covering squeeze. Verify whether the move is fundamental or technical before chasing.
Samsung was the clear laggard at -10.38% — a decline of this magnitude warrants a fundamental review. Check whether this reflects a company-specific negative (guidance cut, regulatory headwind) or macro pressure.
4 of 10 stocks advanced. Negative breadth — more stocks declining than advancing.
