I'm 19 and a student, so I don't have much income at the moment.
Last week I sold my $XDWD (+0.85%) 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 (+0.81%)
$EWI (+0.35%)
$EIN3 (-0.6%)
$FUR (+0.3%) (was already in the portfolio) and $SY1 (+0.18%)
