I'm 19 and a student, so I don't have much income at the moment.
Last week I sold my $XDWD (+0.51%) 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 (+7.89%)
$EWI (+0.68%)
$EIN3 (-1.55%)
$FUR (+0.81%) (was already in the portfolio) and $SY1 (+0.24%)
