BayCurrent Consulting's PAF will double, Fast Retailing's CPAF will stay the same, and Sony Financial Group will be deleted from the index following its spinoff from Sony Corp (6758 JP).

Nikkei 225 Index Rebalance Preview (Sep 2025): Potential Adds, Deletes, PAF, Capping & Other Changes

<ul>
<li>I published a Sep25 Nikkei 225 prediction list last Wednesday. By Friday, we had a new paradigm due to an ad hoc change. That new paradigm informs the September selection. </li>
<li>As it is, I expect one (1) ADD (<a href="https://www.smartkarma.com/entities/shift-inc" target="_blank" data-smartkarma-citation="entities:7266:1" rel="noopener">Shift Inc (3697 JP)</a>) and one (1) DELETE (<a href="https://www.smartkarma.com/entities/tokuyama-corp" target="_blank" data-smartkarma-citation="entities:14781:1" rel="noopener">Tokuyama Corp (4043 JP)</a>) - a prediction which change on a corporate announcement.</li>
<li>My confidence on the ADD is a little lower due to the implications of the choice of Rohm. And the interesting ECM trade for September remains Sony Financial. </li>

My confidence on the ADD is a little lower due to the implications of the choice of Rohm. And the interesting ECM trade for September remains Sony Financial. 


[Quiddity Index] Nikkei 225 Sep25 Rebal: One ADD/DEL, Less Certain Than Before

<ul>
<li>The March 2025 Nikkei 225 review came out with a sparse set of changes. That gives us hints for the September 2025 review.</li>
<li>For the moment, that leads me to believe we get ONE ADD and ONE DELETE though up to three of each is possible.</li>
<li>For now, <a href="https://www.smartkarma.com/entities/fast-retailing-co-ltd" target="_blank" data-smartkarma-citation="entities:751:1" rel="noopener">Fast Retailing (9983 JP)</a> capping is off, but there's an ad hoc coming in late Q3 or early Q4 and the Sony Financial spinoff to look forward to.</li>
