Korea’s Mandatory Treasury Share Cancellation Situation Creates New Passive Flow Dynamics
- KRX may preemptively adjust KOSPI 200 screening, switching from full market cap to market cap excluding treasury shares for index inclusion.
- With treasury-share cancellation likely this quarter, KRX may act before June ’26. For December KOSPI 200, we should run both full-cap and ex-treasury screens; flows could behave unusually.
- Focusing on Hanssem (009240 KS) and Taekwang (003240 KS); borderline, high treasury shares, potential KOSPI 200 exclusion, making them key flow-sensitive setups for December reshuffle.
