@Seebi Actually, he did. He first saved in the FTSE, i.e. with emerging markets. Due to the performance and his own requirements, he is no longer satisfied with this and is saving in the MSCI (i.e. without emerging markets).
Simply leave the old ETF where it is, otherwise #Steuern = less capital = destruction of interest.
In addition, he can avoid the FIFO principle (i.e. sell the most recent shares first => lowest profit => lowest tax burden) when deconsolidating later.
I have it the same way.
First saved in the FTSE, but have now switched to the MSCI. Let's see later, maybe everything, so ACWII. 😉
