Google Finance Wja
Google Finance’s WJA, or World Japanese ADR Index, provides a snapshot of how Japanese companies with American Depositary Receipts (ADRs) traded on U.S. exchanges are performing collectively. ADRs are essentially certificates representing ownership of shares in a foreign company, but traded in U.S. dollars on U.S. markets like the NYSE or NASDAQ. They allow American investors to easily invest in overseas companies without dealing directly with foreign exchanges and currencies.
