Theoretically, it should be the same, but there is a relationship between supply and demand in the secondary market, so the secondary market is only the price, not just the net value, and of course it will not deviate too much. Moreover, the fees are different, and careful people will take advantage of this opportunity to arbitrage.

ETF is the abbreviation of exchange traded fund, which is translated into "transactional open index fund" in Chinese, also known as exchange traded fund. 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 of a specific index, such as SSE 50 Index (199 1.285, 45.79, 2.35%), 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 a basket of stocks it owns, that is, the portfolio of "unit" ETF usually completely copies the underlying index, and its net performance is highly consistent with the specific index it is pegged to. For example, the net performance of SSE 50ETF is highly consistent with the rise and fall of SSE 50 index.

The nature of ETF:

ETF is a special hybrid fund, which overcomes the shortcomings of closed-end funds and open-end funds and integrates their advantages. ETF can track specific indexes, such as SSE 50 Index; Unlike open-end funds, ETF uses a basket of index stocks to purchase and redeem fund shares; Etfs can be listed and traded on exchanges.

ETF is essentially an open-end fund, which is not essentially different from the existing open-end funds. But it also has its own distinct personality in three aspects: first, it can be listed and traded on the exchange, and investors can buy and sell ETF shares directly on the exchange like trading individual stocks and closed-end funds; Second, ETF is basically an index-type open-end fund, but compared with the existing index-type open-end fund, its biggest advantage is that it is listed on the exchange and the transaction is very convenient; Third, its purchase and redemption also has its own characteristics. Investors can only subscribe or redeem ETFs with a basket of stocks corresponding to the index, but not with existing open-end funds for cash subscription and redemption.
