Nikkei 225 Mar25 Rebal – A Big Buy With Buying Shadow, A Bigger Sell, And $2bn of Funding Flows
- The Nikkei 225 March 2025 rebalance is today. The ADD is big, with more to buy later. The SELL is a really big sell in terms of float.
- The Sell, Mitsubishi Logistics (9301 JP), means Max Real World Float doubles. It’s like a huge offering, with warning.
- There’s a big cap trade on Fast Retailing (9983 JP) where timing is not on its side, leaving US$2bn to buy in funding. 25 names at 0.4x ADV to buy.
