These foreign acronyms might tip you off to the fact that a stock is an ADR, but this doesn't work in every case. For example, Honda Motor does not have a foreign suffix yet is also an ADR. That's why the best way to make absolutely certain a stock is an ADR is to look it up on one of the aforementioned ADR sites. Simply key in your ticker or company name in the search field and hit enter. If your company comes up, it's an ADR; if it doesn't, it's not. Pretty simple.
