📝 US Market Wrap

■ Market Overview & Leaders

US equities roared to fresh records as easing Iran tensions and strong earnings lifted sentiment across the board. The Nasdaq led with a 2.59% surge to 26,584.99, the S&P 500 climbed 1.79% to 7,736.52, and the Dow added 1.71% to close at 54,085.88. Stealing the show was the PHLX Semiconductor Index, which rocketed 6.55% to 12,179.26 — a move set to reverberate through Asian chip names overnight. Intel (+10.8%), Qualcomm (+7.3%), AMD (+7.0%), and Broadcom (+6.6%) paced the rally, while Caterpillar (+5.6%) added industrial muscle.

■ Flows & Breadth

Breadth was solidly positive, with 30 advancers against 10 decliners among large caps — confirming the broad-based nature of today’s rally rather than a narrow chip-driven pop. Defensive and energy names lagged: Amazon (-2.3%), UnitedHealth (-1.9%), Chevron (-1.4%), ExxonMobil (-0.7%), and Costco (-0.7%) all slipped. Notably, the VIX rose 4.04% to 16.50 even as indices hit highs — a mild divergence worth watching. USD/KRW eased 0.44% to 1,429.43, reflecting reduced risk aversion.

■ Takeaway

Today’s action was a textbook risk-on session — semis roared, breadth confirmed the move, and geopolitical relief provided the spark. 🚀

💡 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.

💡 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.
