I would just stop the ETF and only sell it if you need the money/retirement... The large cash position surprised me a bit. Put a large part of it in the World ETF. You'll have to hold Biontech for a very long time until it goes up again, which is a great savings plan ratio.
@income_magician_28 Hey Magican, thanks for your feedback. I have to pay off the last big installment on my car soon (18k). That's where the large cash position comes from.
