@Mark777 hope that it is not a big position 🙈 depending on that you would have better opportunities elsewhere, it just must not be a thorn in my side, for example if novo was in the red with me I would buy more no matter what as long as the balances fit. For positions that I strongly support and am convinced of.
You should also be able to sleep peacefully in the red, Bayer was such a case for me, I didn't care that I was in the red.
