<li>In December, I thought the March 2025 Nikkei 225 Rebalance was going to be 2 ADDs 2 DELETEs and a double-capping for Fast Retailing. </li>
<li>Fast Retailing has fallen sharply vs Nikkei 225, and another stock has announced a large-multiple share split, making it a strong candidate for Nikkei 225 ADDITION in March 2025.</li>
<li>There is short-term path risk on all three ADDs, but they are definitely worth watching. Keep an eye out for separate insights on two of these names.</li>

In December, I thought the March 2025 Nikkei 225 Rebalance was going to be 2 ADDs 2 DELETEs and a double-capping for Fast Retailing. 
Fast Retailing has fallen sharply vs Nikkei 225, and another stock has announced a large-multiple share split, making it a strong candidate for Nikkei 225 ADDITION in March 2025.
There is short-term path risk on all three ADDs, but they are definitely worth watching. Keep an eye out for separate insights on two of these names.


[Quiddity Index Jan25] Nikkei 225 Mar Rebal: 3 IN, 3 OUT, $3bn One Way

<ul>
<li>The Sep24 Nikkei 225 Rebal was odd. They could have done 3. They did 2. For now, I still see 2 IN and 2 OUT for the Mar25 Nikkei225 Rebal.</li>
<li>There is also a DOUBLE-capping event for Fast Retailing which on 8% outperformance could become a TRIPLE-capping event. For now, the trade is shaping up to be US$7bn a side.</li>
<li>There is still a tech bent to potential ADDs. Some Consumer Goods stocks need stock splits to get in. Longer-term, the TOPIX Methodology Rejig is an interesting problem set.</li>
