KOSPI Drops -5.72% in a Day, 4 Weekend Checks After a Volatile Week
TL;DR
- This week KOSPI rose from 6,516.27 (Mon close) to 7,096.89 (Thu), up 8.9%, then closed Friday down -5.72% at 6,690.62.
- A +4.40% day and a -5.72% day occurred in the same week. Volatility has increased more than directional conviction.
- Weekend work is about checks, not forecasts. The four checklist items below are sufficient.
Experiencing both sharp gains and sharp losses in one week clouds judgment. In such times, start again with the numbers.
This week, by the numbers
| Date | KOSPI Close | Change | KOSDAQ Close | Change |
|---|---|---|---|---|
| 7/20 (Mon) | 6,516.27 | -4.46% | 749.64 | -5.33% |
| 7/21 (Tue) | 6,747.95 | +3.56% | 753.34 | +0.49% |
| 7/22 (Wed) | 6,797.70 | +0.74% | 751.09 | -0.30% |
| 7/23 (Thu) | 7,096.89 | +4.40% | 790.28 | +5.22% |
| 7/24 (Fri) | 6,690.62 | -5.72% | 748.22 | -5.32% |
Observed facts are as follows.
- KOSPI recovered Monday's drop over three days to reach 7,096.89 on Thursday, then returned -406.27 points on Friday. The swing from weekly low (Mon close) to high (Thu close) was 8.9%.
- After that volatility, Friday's KOSPI close is 2.7% above Monday's close. KOSDAQ at 748.22 effectively returned to Monday's level.
- Thursday's rise (+4.40%) and Friday's fall (-5.72%) are similar in magnitude. In such a week, you cannot determine direction from a single daily move.
Four weekend checks
1. Review your holdings performance for the week
Daily moves swung all week. Check where each holding started and ended the week, and whether its drop exceeded the index. Use My Stocks Radar to see end-of-day briefings for tracked names.
2. Separate themes that fell sharply from those that held up
Even in a -5% day, theme-level resilience differs. Themes that fell less on Friday often become candidates in the next phase, while themes that only spike on up days and surrender on down days deserve scrutiny. Compare weekly theme flows on Theme Explorer.
3. Check weightings and cash
Often what shakes you on a drop is position sizing, not the stock. If one position is half the portfolio, surviving a -5% day is hard. Write down position weights, cash ratio, and whether you have capacity to add if declines continue.
4. Predefine what to confirm on the next session
Make a checklist to confirm, not a prediction. Decide if the open gaps, whether turnover holds Friday levels, and whether Friday's top decliner themes bounce. Following a list reduces emotion when the market opens.
