$BATS (+0.27%) I added this share to my portfolio a few months ago at a buy in of 29.3 for 10k.

Now the profit stands at 2.4k including a distribution of approx. 270€.

I am undecided as to whether I should continue with the buy & hold principle or sell part of the position so that it is back at 10k and switch to other shares such as $GOOGL (-5.23%)
$IMB (-0.07%) or ETFs.

What would you do?
