An American depositary receipt (ADR) is a foreign stock that trades in the United States but represents a specified number of shares in a foreign corporation. ADRs are bought and sold on American markets just like regular stocks, and are issued/sponsored in the U.S. by a bank or brokerage.

Some of ADRs are also traded in their host countries/regions. Most of them are traded in parity between US and their host countries/regions. US investors/traders must know their parity prices of the stocks in their host countries/regions when investing/trading those stocks.

This website tracks the parity prices among stocks that are traded in both US and their host countries/regions, and lively calculates the ADR parity price and the price differences. Hopefully, the site can help users to take advantages of the price differences and profit from it.

If you have more stocks that traded in both US and a host country/region, and would like to add to our list, please fill up the request here.
