📝 Market Wrap

■ Market Overview & Leaders

KOSPI tumbled 1.55% to 6,869.80, slipping below the psychologically key 7,000 level, while KOSDAQ was hit harder, sliding 3.51% to 834.31. The selloff tracked broader regional weakness — Nikkei fell 1.82%, TAIEX dropped 1.10%, and even the S&P 500 eased 0.17% overnight. The won firmed slightly, with USD/KRW down 0.22% to 1,412.28. Large-cap leadership was notably narrow: HMM (+6.6%), S-Oil (+4.1%) and Samsung Life (+3.2%) bucked the trend, while tech-adjacent names bore the brunt — Samsung Electro-Mechanics (-7.6%), Samsung SDS (-6.2%) and LG (-6.1%) led decliners.

■ Flows & Breadth

Breadth confirmed the weak tape: only 11 of 40 large-caps advanced versus 27 decliners, reinforcing that the index-level damage was broad-based rather than isolated to a few heavyweights. Headlines note institutions and individuals both dumping shares as KOSPI broke below 7,000, consistent with today’s action. The system’s risk gate remains blocked amid a high-volatility regime — a signal that dispersion and swings are prone to intensify near-term.

■ Takeaway

With breadth deteriorating and volatility controls active, foreign investors should stay alert — this pullback looks broad, not just a single-sector wobble. 📉

💡 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: INFLATION — Inflationary — growth with rising price pressure
  • Allocation guide: Tilt toward real assets and value
  • Crash gate: 🔴 Blocking new entries
  • 5-day index return +8.0% (threshold -8%) · 20-day realized vol 92.3 (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.

💡 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.

🩺 System Health Check

  • Risk gate: 🔴 Blocking new entries
  •   [KR Crash Gate] 실현변동성 20일 92.3 ≥ 40 — 패닉 국면, 신규 진입 차단
  • Circuit breaker: 🟢 Normal
  • Entry attempts blocked by the gate today: 2
💡 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.

🤖 System Trading Status

No positions closed today.

💡 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.
