What to watch for the next session
- Both markets fell sharply (KOSPI -5.80%, KOSDAQ -1.17%), so check macro shock indicators. The strength of any rebound next session will be a key input for trend assessment.
- Bottom 3 themes average -5.61%, confirming concentrated selling in weak themes. Short-term bounce from oversold levels is plausible, but do not treat it as a confirmed trend reversal.
Avoid making trading decisions on a single trading-day signal. Combine a 5-day or longer trend with macro developments before concluding.
