Pour rappel le DAX30 devient le DAX40 le 20 septembre, voici le message de mon broker :
The Germany 30’s name will be changing, but your positions won’t
As of Monday 20 September 2021, the number of constituents in the Deutsche Börse DAX index will increase from 30 to 40. For this reason, the name of our Germany 30 index will change to the Germany 40 index on that date.
This change will have no material impact on your positions. All open positions will continue to be priced and settled using the final settlement level of the DAX future as reported by Eurex.
