ADRs and Cross-Listings

A US investor who wants to own shares of a company listed only in, say, Tokyo or São Paulo normally has to open a foreign brokerage account, convert currency, and deal with foreign settlement rules. An American Depositary Receipt (ADR) avoids all of that: a US bank (the depositary) buys and holds a block of the foreign shares in the home market, then issues receipts against them that trade on a US exchange in dollars, through a normal US brokerage account, just like a domestic stock.

Each ADR represents a fixed ratio of underlying shares — one ADR might equal two ordinary shares, or one-tenth of a share, chosen so the ADR's dollar price lands in a familiar range. The depositary bank passes through dividends (converted to dollars, minus a small fee) and corporate-action adjustments, but the ADR holder doesn't get voting rights or other privileges identical to a direct shareholder in every jurisdiction.

A cross-listing, by contrast, is the same class of shares listed for trading directly on more than one exchange — a company might list ordinary shares on both the London and Hong Kong exchanges, with no depositary bank or receipt structure involved, and no fixed conversion ratio because it's literally the same security in both venues. ADRs and cross-listed shares should trade at levels consistent with each other after adjusting for currency and the ADR ratio, and persistent gaps are what ADR arbitrage strategies try to exploit.
