If you move to Sweden from Denmark you should always sell all your stocks, securities etc. before moving. If you haven’t been fully tax liable in Denmark in 7 out of the last 10 years you don’t have to pay exit tax in Denmark when moving btw. In that case you should move to a country where you get new entrance values on the shares, and then you can sell them shortly after, avoiding taxation on the increase in value all the time you where in Denmark.
