It’s true that redemptions in Portugal Liquid Opportunities can take up to six months officially, although the manager claims to generally process them in less than a month. This fund also maximizes the non-Portuguese exposure you can get, meaning you only have around €300K exposed to the Portuguese market.
Regarding the potential issue I see for the fund tracking the PSI-20 index (BPI, IMGA, not sure about Sixty Degrees), that may just mostly be theoretical, but I think it’s a risk worth highlighting nonetheless.
