📊Anatomy of the Crash
March 4th's -12.06% was not a simple decline. Circuit breakers triggered twice, halting trading for 20 minutes each time. At its worst intraday point, KOSPI was down over 14%. Key numbers: - KOSPI: 6,307 → 5,094 (-19.2% in 7 trading days) - Samsung: 218,000 → 172,200 won (-21%) - SK Hynix: 1,099,000 → 849,000 won (-23%) - USD/KRW: 1,427 → 1,483 (won -3.8%)
- ▸KOSPI down -19.2% in 7 trading days
- ▸Samsung -21%, SK Hynix -23%
- ▸Won crashed to 1,483 per dollar
📈Quality of the Bounce
Three criteria to evaluate the +9.6% bounce quality: 1. Volume: Bounce-day volume should be 80%+ of crash-day volume for a strong bounce. This bounce was approximately 75%. 2. Sector breadth: Did all sectors bounce evenly? This bounce was semiconductor-led and concentrated. 3. Foreign flows: Did foreigners switch to net buying? Still net selling.
- ▸Volume at 75% — moderate level
- ▸Semiconductor-concentrated bounce — lacking breadth
- ▸Foreigners still net selling — warning signal
📜Historical Precedents
Post-circuit-breaker patterns in the Korean market: - March 2020 (COVID): -8% circuit breaker → next day +8.6% bounce → retest 2 weeks later → real bottom - October 2008 (GFC): Circuit breaker → bounce → new low 3 weeks later Common pattern: Strong bounce immediately after circuit breaker → retest of lows within 2-4 weeks → real bottom confirmed after retest. Historically, the first bounce is the actual bottom only about 40% of the time.
🎯Key Technical Levels
Critical price levels to monitor over the next 2-4 weeks: Support: - 5,094 (March 4 close) — if held, bottom confirmed - 4,800 — next major support Resistance: - 5,800 — first resistance - 6,100 — trend recovery confirmation If KOSPI holds 5,094, the bottom is confirmed. If it breaks below, a decline to 4,800 is possible.
- ▸5,094 holds = bottom confirmed
- ▸5,094 breaks = 4,800 test
- ▸5,800 recovery = normalization begins

Bottom Confirmed
Dead Cat Bounce
📍오늘의 핵심 체크리스트
- ■Monitor KOSPI daily close relative to 5,094
- ■Track daily foreign net buy/sell data
- ■Watch USD/KRW for breach above 1,500
- ■Follow Hormuz Strait geopolitical developments
- ■Check if VIX stays above 25
- ■Monitor Samsung/SK Hynix individual support levels
🎯결론
Historically, only 40% of first bounces after circuit breakers mark the real bottom. 60% see a retest within 2-4 weeks. Given persistent foreign selling, semiconductor-concentrated bounce, and won weakness, the probability of a retest is elevated. Scale-in buying with cash reserves is the prudent strategy. Lose less. Last longer.
