ADRs or American Depository Receipts are one way that U.S. investors can invest in non-U.S. companies. ADRs are not shares of stock. They are held by a custodian for an investor. Even though they are listed as being traded on exchanges, they are not traded as stock on these exchanges. If you use their ticker symbols on web sites that give stock quotes, you will not get a price for them. There are several sites devoted to ADRs. The companies listed at these sites will vary depending on whether the bank holds these ADRs.
