I have a question for you. So far I have only saved one $IWDA (-0.04%) saved. However, I would now like to diversify this core more. In future, I would like to invest 65% in the $IWDA (-0.04%) 20% in a $XMME (+0.16%) 10% in $EXSA (+0.37%) and 5% in $EWG2 (+0.8%) into one. Should I now save the amount I have already saved with the new allocation from next month or should I divide the sums between the new ETFs until the allocation is correct?
