Weekly Trends and Themes
1. US Market Performance
S&P 500: +0.79% | Nasdaq: +1.77% | Dow: -0.43%
The S&P 500 advanced +0.79% for the week, with Nasdaq outperforming at +1.77%. Gains were concentrated in growth/tech; defensive sectors lagged.
Magnificent 7: 5 of 7 Mag7 stocks advanced. Best: Amazon (+6.33%), worst: Tesla (-4.13%).
Takeaway: Consolidation week — no tactical change needed.
2. Korean Market Performance
KOSPI: +4.13% | KOSDAQ: +2.47% (weekly)
KOSPI surged +4.13% — a strong weekly gain suggesting genuine institutional re-entry, not just short-covering.
KOSDAQ moderately higher (+2.47%), underperforming KOSPI — investors preferring large-cap stability.
Among Korean blue chips: SK Hynix led (+4.80%), Hyundai lagged (-2.66%).
Takeaway: Strong week for Korean markets — partial position add appropriate.
3. Currency Impact (KRW/USD)
Weekly KRW Move: +0.38% ₩1,471 → ₩1,476
The won weakened modestly (+0.38%, ₩1,471 → ₩1,476) — a mild headwind for USD investors in Korean stocks.
Investor Implication: Minor FX impact; no immediate hedging action needed.
Export sector note: Stable KRW — no meaningful FX-driven earnings revision expected.
4. Treasury Yields
10Y: 4.32% → 4.34% (+2 bps)
The 10Y Treasury yield held steady at ~4.34% (+2 bps for the week) — no yield-driven repricing of equities.
Market Implication: Stable rates support growth stock multiples.
5. Key Weekly Observation
- Korea outperformed the US by 3.3pp this week — unusual divergence; watch for foreign net buying data to confirm institutional re-entry.
- Wide Mag7 dispersion this week (10.5pp between best and worst) — stock-pickers’ market; index-level moves understate individual name volatility.

Commentary:
Amazon was the standout winner at +6.33% — 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.
Tesla underperformed at -4.13% — watch whether the weakness continues into next week or reverses.
7 of 10 stocks advanced. Breadth is healthy — more gainers than losers.
