I'm 19 and a student, so I don't have much income at the moment.
Last week I sold my $XDWD (+0.12%) 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 (+1.17%)
$EWI (-0.83%)
$EIN3 (-0.97%)
$FUR (+1.34%) (was already in the portfolio) and $SY1 (+0.09%)
