📝 Market Wrap

■ Market Overview & Leaders

KOSPI cratered 4.46% to 6,516.27, with KOSDAQ down even harder at 5.29% to 749.97 — Korea’s selloff dwarfed regional peers, as Nikkei fell 4.03%, S&P 500 slipped 1.01%, and Taiwan TAIEX eased just 0.52%. Headlines frame Korea’s AI- and debt-heavy market as now setting the tone for global tech volatility, with memory chip names extending losses ahead of US Big Tech earnings. Samsung group stocks bore the brunt — Samsung Fire & Marine (-14.1%), Samsung Life (-8.9%), Samsung C&T (-8.2%) — while defensive/energy names like KT (+2.1%) and S-Oil (+1.2%) bucked the trend as oil kept climbing.

■ Flows & Breadth

Breadth confirmed the carnage: just 3 large-cap advancers against 37 decliners, aligning with the index’s steep drop — no divergence here, but the concentration of pain in Samsung affiliates versus a handful of energy/telecom gainers underscores how narrow leadership can amplify swings. The won stayed steady near 1,479.29, barely budging despite equity stress. Notably, the system risk gate has been triggered, blocking trades amid this high-volatility regime.

■ Takeaway

With volatility gates active and breadth this lopsided, Korea’s market looks prone to further whipsaws as global tech sentiment shifts. Caution is warranted given concentration risk. 📉

📊 Market Snapshot

Index Close 1D 5D 1M vs Peak
KOSPI 6,516.27 -4.46% -12.8% -28.1% -28.5%
KOSDAQ 749.97 -5.29% -10.4% -25.1% -38.8%

💡 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 79, USD/KRW 1,479)
  • Allocation guide: Defensive stance: reduced equity exposure, higher cash allocation
  • Crash gate: 🔴 Blocking new entries
  • 5-day index return -6.5% (threshold -8%) · 20-day realized vol 78.2 (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.

🩺 System Health Check

  • Risk gate: 🔴 Blocking new entries
  •   [KR Crash Gate] 실현변동성 20일 78.2 ≥ 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.

🤖 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.
