<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>

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. 
As it is, I expect one (1) ADD (Shift Inc (3697 JP)) and one (1) DELETE (Tokuyama Corp (4043 JP)) - a prediction which change on a corporate announcement.
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>
