Oh wise ones. Looking for recommendations on how to clean up my portfolio. Over reliant on the US I purchased during this down turn some

or the below but huge overlap..

Should I loose the SP500 and/or Nasdaq and which one to choose from the below :

$VWCE (-0,06%)

$GGRG (+0,23%)

$IWDA (+0%)

$TDIV (-0,11%) (the most diversified option)

im also thinking of adding $EWSA (-0,1%) small cap world, but it is a small fund, max 5% allocation. Good, bad ?

Thank you!
