Recently I received notice that an ADR from a stable company (i.e. NZT) is going to be delisted from the NYSE to save on the administrative costs. The company itself is solid and regularly distributes dividends to share holders. Furthermore, they will continue to be listed on their home stock exchange so I'm not too concerned with the fundamentals of the company.
However, I am concerned with being able to sell the shares at a point in the future. Given that, would it be better to sell off the shares now and take some nominal gains, or retain them until such time the stock should be sold for other reasons?
