📝 Market Wrap

■ Market Overview & Leaders

Korean equities were routed as KOSPI collapsed 10.84% to 6,023.63 and KOSDAQ dropped 7.72% to 705.82, far outpacing regional peers — Nikkei fell 3.95%, TAIEX 4.65%, while the S&P 500 was flat (+0.02%). Chipmakers bore the brunt: Samsung Electronics (-13.4%), SK Hynix (-14.6%), Samsung Electro-Mechanics (-15.9%) and SK Telecom (-16.0%) led losses, reflecting the AI-stock unwind flagged in headlines. Only KT (+0.2%) held green among large caps.

■ Flows & Breadth

Breadth confirms the severity, not just concentration: among 40 large-caps, just 1 advanced against 39 decliners — a rare case where index-level and breadth-level pain aligned rather than diverged. Won weakness (USD/KRW +0.20% to 1,460.98) added pressure. The exchange’s system risk gate is currently blocking trades amid the high-volatility regime, underscoring how disorderly the selloff has become.

■ Takeaway

With chipmakers dragging both index and breadth lower in tandem, and Korea’s market now tightly coupled to U.S. tech sentiment per CNBC, foreign investors should stay alert — further AI-related volatility abroad could keep KOSPI prone to outsized swings relative to peers. 📉

📊 Market Snapshot

Index Close 1D 5D 1M vs Peak
KOSPI 6,023.63 -10.84% -10.7% -28.4% -33.9%
KOSDAQ 705.82 -7.72% -6.3% -17.1% -42.4%

Taiwan TAIEX 41,603 -4.65% -5.9% -6.7% -12.9%
💡 Korea Market 101
KOSPI is Korea’s benchmark of large-cap stocks (think S&P 500 of Korea); KOSDAQ lists smaller, growth-oriented companies (closer to Nasdaq). ‘vs Peak’ shows how far the index sits below its recent high — a large negative number means a deep drawdown. USD/KRW matters enormously for foreign investors: if you invest in dollars, a rising USD/KRW (weaker won) eats into your returns even when stock prices hold, and sustained won weakness often coincides with foreign outflows from Korean equities.

💡 Korea Market 101
Today’s biggest large-cap winners and losers. When stocks in the same industry move together, money is rotating into (or out of) that sector. Korea’s index is heavily concentrated in semiconductors — Samsung Electronics and SK Hynix alone can drive the whole market.

💡 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: RISK-OFF — Risk-off — investors are sheltering from risk assets (realized vol 80, USD/KRW 1,461)
  • Allocation guide: Defensive stance: reduced equity exposure, higher cash allocation
  • Crash gate: 🔴 Blocking new entries
  • 5-day index return -1.9% (threshold -8%) · 20-day realized vol 73.2 (threshold 40) — the system automatically resumes new entries once both metrics normalize.
💡 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.

  • Risk gate: 🔴 Blocking new entries
  •   [KR Crash Gate] 실현변동성 20일 73.2 ≥ 40 — 패닉 국면, 신규 진입 차단
  • Circuit breaker: 🟢 Normal
  • Entry attempts blocked by the gate today: 0
💡 Korea Market 101
The system audits itself daily. The ‘risk gate’ is the traffic light that stops buying during crashes; the ‘circuit breaker’ is an automatic brake that pauses trading after consecutive losses. A high blocked count is good news — it means the safety systems held back purchases on a dangerous day.

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.
