ETF is the abbreviation of Exchange Tradefund, which is translated into "transactional open index fund" in Chinese, also known as ExchangeTradedFund. ETF is an open-end securities investment fund product listed and traded on the exchange, and the trading procedure is exactly the same as that of stocks. The assets managed by ETF are stock portfolios. The types of stocks in this portfolio are the same as those in a specific index, such as the SSE 50 Index, and the number of each stock is consistent with the proportion of the constituent stocks of this index. The transaction price of ETF depends on the value of its stock portfolio, that is, the "net asset value of unit fund".

The etf of Shanghai-Hong Kong Stock Connect refers to the exchange-traded fund of Shanghai-Hong Kong Stock Connect.
