Clarifying the Universe for Key Korean Index Rebalancings in September
- KRX sector indices use TMI as their universe, while KOSPI cap-tier indices use all KOSPI-listed stocks, creating a key difference in universe selection.
- KRX sector indices rebalance annually after September expiry, using September TMI (reviewed end-July) as their universe—not the June version, despite common confusion.
- Pre-Positioning is uncertain; market likely waits for August’s September TMI results before building positions. KOSPI cap indices use August review date, with similar flow patterns starting six weeks prior.
