I accidentally put my savings plan with Trade Republic on the ADR instead of the original share a few months ago. Due to the fluctuations in the dollar, it seems to have performed even slightly better than the share itself when traded in euros.
Apart from the currency fluctuations, will I suffer any significant disadvantages from the ADR in the long term? For example, in terms of taxes or extra fees. I am a German investor in Germany, with no ties to Switzerland or the USA. The position is relatively small, so I would rather avoid transaction costs for an unbalancing.
