Securities etf (referring to trading open index fund) and securities B (referring to B shares) have their own advantages and characteristics, and they are not comparable. The relevant introduction is as follows:

1. Advantages and characteristics of securities etf (referring to transactional open index fund):

Combined with the operating characteristics of closed-end funds and open-end funds, investors can purchase or redeem fund shares from fund management companies, and at the same time, they can buy and sell ETF shares in the secondary market at market prices like closed-end funds. However, the purchase and redemption must be exchanged for a basket of shares or a basket of shares.

Because there are both secondary market transactions and subscription and redemption mechanisms, investors can carry out arbitrage transactions when there is a difference between the market price of ETF and the net value of fund units. The existence of arbitrage mechanism makes ETF avoid the common discount problem of closed-end funds.

2. Advantages and characteristics of Securities B (B shares):

B shares are not physical shares. They rely on paperless electronic bookkeeping and implement the "T+3" delivery system, with price limit (65,438+00%). The participating investors are Hong Kong, Macao and Taiwan residents and foreigners, and mainland residents with legal foreign exchange deposits can also invest.

Extended data:

Introduction to trading funds of stock exchange:

1. Compared with closed-end funds of securities ETFs, they are similar in that they are all listed on the exchange, just like stocks, and can be traded at any time in one day. The difference is that:

1, ETF is more transparent. Because investors can purchase/redeem continuously, the frequency response of asking fund managers to announce net value and portfolio is accelerated.

2. Due to the existence of the continuous subscription/redemption mechanism, theoretically there will not be too much discount/premium between the net value of ETF and the market price.

Second, compared with open-end funds, ETF funds have two advantages:

1.ETF is listed on the exchange and can be traded at any time within one day, which is convenient for trading. Open-end funds can only be opened once a day, and investors only have one trading opportunity every day (that is, subscription and redemption);

2.ETF redemption is to deliver a basket of stocks without keeping cash, which is convenient for managers to operate and can improve the management efficiency of fund investment.
