Is it better to buy US stocks on US stock exchanges as a European?
No, there are neither advantages nor disadvantages. I'll take on this question from an accounting standpoint.   Financial statements, the tools at which the market determines (amongst other things) the value of a stock, are converted at year end to the home currency (see 1.1.3).If Company A has revenue of 100,000 USD and the conversion to EUR is .89, revenue in the European market will be reported as 89,000 EUR. These valuations, along with ratios, analysis, and "expert" opinions determine if a person should own shares in Company A.  Now, if we're talking about comparing markets this is a entirely different question.  Example:  Should I buy stock of Company A, who is in the American market (as an European)?  Should I buy stock of Company B, who is in the European market (as an American)? I would recommend this as additional level of diversification of your portfolio to inlcude possible large inflation of either the currency. The possible gains of this foreign exchange may be greater if one or the other currency becomes weak.
