The Invesco Golden Dragon China ETF (PGJ) is designed to mirror the performance of the NASDAQ Golden Dragon China Index. To achieve this objective, the fund typically allocates a minimum of 90% of its total assets to the shares of companies included in that index. The NASDAQ Golden Dragon China Index, in turn, comprises companies listed on US stock exchanges that are either headquartered or legally established in the People's Republic of China, or generate the vast majority of their income from that country. Both the ETF's portfolio and its underlying benchmark index undergo quarterly adjustments and updates.
