The Math of Bounces: +9.6% Is Not Enough — KOSPI Still -3.6% Below Pre-Crash
KOSPI posted a historic +9.6% bounce. But math doesn't lie. After losing -12%, you need +13.65% to recover. +9.6% falls short. Emotions recovered. The account hasn't.

The Math of Bounces
The most important lesson of this week: percentage math is asymmetric. If you lose 12%, you need 13.65% to recover — not 12%.
Today's +9.6% feels like "almost recovered," but you're actually still -3.6% below where you started. This is why drawdown control matters more than returns. Losing less beats gaining more.
Who Bought at the Bottom?
Institutional buying returned aggressively. Some retail investors who panic-sold yesterday are now buying back at higher prices. The disposition effect in reverse: selling at the bottom, buying at the bounce.
Those who had a plan and cash — they're today's beneficiaries.
Bias of the Day: Anchoring
After watching -12%, our brain anchors to that extreme. So +9.6% feels like an enormous recovery. But the math says otherwise.
Anchoring bias makes us evaluate today's move relative to yesterday's crash, not relative to where we started. KOSPI was 6,307 just 7 trading days ago. Today it closed at 5,584. That's -11.5%. The "recovery" narrative is an anchoring illusion.
It's Not Over Yet
One bounce doesn't make a bottom. History shows that after circuit-breaker events, markets often retest lows within 2-4 weeks.
The real test: can KOSPI hold above 5,094 (yesterday's close)? If yes, the bottom is likely in. If no, yesterday's panic was just the first wave.
Key Levels
| Asset | Support | Resistance | Bias |
|---|---|---|---|
| KOSPI | 5,094 | 5,800 | Neutral — bottom needs confirmation |
| Samsung | 172,200 | 200,000 | Neutral |
| SK Hynix | 849,000 | 1,000,000 | Neutral — 1M won recovery is key |
| BTC | $70,000 | $76,000 | Bullish |
Scenarios
If: Bounce continues + geopolitical de-escalation
Then: KOSPI recovers 5,800, normalization begins
If: Bounce fades (dead cat bounce)
Then: 5,094 retested within 2-4 weeks
TTL Take
KOSPI +9.6%. A historic bounce. Samsung +11.3%, SK Hynix +10.8%. Looking at the numbers alone, it seems like yesterday's nightmare is over.
But math doesn't lie. After -12%, you need +13.65% to get back to even. +9.6% falls short. Seven trading days ago, KOSPI was at 6,307. Today: 5,584. Still -11.5% below. Anchoring bias makes +9.6% feel like "almost recovered," but your account balance tells a different story.
Emotions recovered. The account hasn't.
Lose less. Last longer.
