I'm 19 and a student, so I don't have much income at the moment.
Last week I sold my $XDWD (-0.39%) 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 (-1.94%)
$EWI (-0.01%)
$EIN3 (-0.51%)
$FUR (-0.4%) (was already in the portfolio) and $SY1 (-0.42%)
