I don't know where in MVIS website that I can download the spreadsheet showing the number of AZZ shares within the MVIS Global Rare Earth as @BP2137 has shown us. But based on the info available, before last Friday 17/12/2021 and when the market opens today, my rough calculation is as follows
AVZ constitutes 0.22% = 5m shares (before last Friday)
Now, (5m x 5.11%) / 0.22% = 116m shares. That is an additional 111m shares. This is only a rough calculation only (as multiply 5.11% then divided by 0.22% is not quite correct - but pretty close).
