I'm 19 and a student, so I don't have much income at the moment.
Last week I sold my $XDWD (-0,22%) last week to reduce my USA share, as I assume that the USA will lose its supremacy, which will benefit the EU. (Hence the Dax and Greece etf).
On the watchlist are (and will probably be bought in a crash)
$PNG (-1,89%)
$EWI (+0,21%)
$EIN3 (+3,05%)
$FUR (+4,07%) (was already in the portfolio) and $SY1 (-1,29%)
