ETF: Traded open-end index fund, also commonly known as Exchange Traded Funds ("ETF" for short), is an open-end fund that is listed and traded on an exchange and has variable fund shares.

There are two advantages: First, ETFs are listed on exchanges and can be traded at any time during the day, which provides transaction convenience.

Second, when the ETF is redeemed, a basket of stocks is delivered, without the need to retain cash, which is convenient for managers to operate and can improve the management efficiency of fund investment.

Transaction costs are low, and index investments often feature low management fees and low transaction costs.

High transparency.

ETF adopts passive management and completely replicates the constituent stocks of the index as the fund investment portfolio and investment return rate. The fund holdings are quite transparent. It is easier for investors to understand the characteristics of the investment portfolio and fully grasp the status of the investment portfolio to make appropriate expectations.

Recommend a few: 50ETF, 180ETF, dividend ETF, governance ETF, Shenzhen 100ETF, small and medium-sized ETF and deep into ETF.
