📝 US Market Wrap

■ Market Overview & Leaders

Wall Street closed lower Tuesday as fading hopes for a US-Iran deal and climbing oil prices rattled sentiment. The S&P 500 slipped 0.32% to 7,728.20, the Nasdaq fell 0.60% to 26,445.45, and the Dow eased 0.34% to 53,791.85. Notably, the Philadelphia Semiconductor Index bucked the trend, gaining 0.87% to 12,098.47 — a constructive signal for chip sentiment heading into Asian trade. VIX ticked down 1.16% to 15.28, suggesting hedging demand stayed modest despite the geopolitical noise. Home Depot, AMD, Chevron, AbbVie and Meta led gainers, while Alphabet (-3.8%), Oracle (-3.7%) and Adobe (-3.4%) dragged the megacap complex lower.

■ Flows & Breadth

Breadth was dead even among large caps — 20 advancers versus 20 decliners — despite the Nasdaq’s sharper 0.60% decline, hinting the drop was concentrated in a handful of heavyweight tech names rather than broad selling. USD/KRW rose 0.38% to 1,412.39, reflecting some dollar firmness amid the risk-off tone.

■ Takeaway

Headline indices sagged on oil-driven jitters, but flat breadth and a firmer SOX suggest underlying resilience beneath megacap tech weakness. 📊

💡 Korea Market 101
Alongside the majors, we track the PHLX Semiconductor Index (SOX) — the overnight driver of Korean chipmakers like Samsung Electronics and SK Hynix. A big SOX move often sets the tone for the next KOSPI session. VIX under 20 is calm; above 30 signals fear.

Today’s biggest US large-cap moves. US sector rotation frequently leads the Korean market by a day — watching where money flows here gives a preview of tomorrow’s Seoul session.

💡 Korea Market 101
A ranking of where money is flowing across industries. A higher score means stronger recent price action. ‘Growth’ sectors (chips, IT) lead in good times; ‘Defensive’ sectors (telecom, staples) hold up in downturns. When defensives cluster at the top, the market has turned cautious.

💡 Korea Market 101
What the index alone hides. ‘% above 200-DMA’ is the share of stocks in a long-term uptrend — below 50% means most stocks are in long-term decline even if the index isn’t. Comparing new 52-week highs vs lows reveals whether it’s truly a bull or bear tape underneath the headline number.

💡 Korea Market 101
English-language coverage of the Korean market. Two Korea-specific terms worth knowing: a ‘circuit breaker’ halts all trading when the index moves too fast, and a ‘sidecar’ briefly suspends program trading — both are exchange safety mechanisms you’ll see mentioned on volatile days.

💡 Korea Market 101
The bigger picture around equities. A rising US 10-year yield raises borrowing costs and pressures stocks. A stronger dollar (higher DXY) tends to pull foreign capital out of emerging markets like Korea. Gold is the fear gauge, oil proxies inflation, and Bitcoin reflects risk appetite.

🌡️ Regime & Risk Diagnosis

  • Regime call: INFLATION — Inflationary — growth with rising price pressure
  • Allocation guide: Tilt toward real assets and value
💡 Korea Market 101
Think of the ‘regime’ as market weather. RISK-OFF means investors are sheltering in cash rather than risk assets. ‘Realized volatility’ is a thermometer for how wildly prices swing — under 20 is calm, above 40 is panic territory. The ‘crash gate’ is our system’s traffic light: when the Korean market falls too fast, it turns red and the system stops buying on its own, then reopens automatically when conditions settle. (Note: the regime diagnosis text is produced in Korean by the engine.)

💡 Korea Market 101
A scanner screens hundreds of Korean and US stocks daily and scores them on technical and fundamental criteria (max 100). ‘Target’ is the expected gain if the setup works; ‘Stop’ is the pre-committed maximum loss if it doesn’t — the system always defines the exit before entering. ‘Swing’ rides multi-day trends; ‘Squeeze’ waits for dormant stocks to break out. ‘Watching’ means signal registered but not bought; ‘Held’ means the system actually owns it. ⚠️ This is an algorithm’s candidate list, not investment advice. Korean stock names are shown in Korean.

Open positions P&L chart

💡 Korea Market 101
‘Closed’ = sold; ‘open’ = still held. Unrealized P&L assumes selling right now — nothing is locked in until sold. ‘STOP’ means the pre-set safety line was hit and the system sold automatically; ‘ROTATION_EXIT’ means it swapped into a stronger candidate. The one rule this system lives by: cut losses early and automatically, let winners run.
