SSE 5ETF cannot make fixed investment. However, it can be purchased and redeemed at banks and fund websites.

the reason why p>ETF takes SSE 5 as the target is that these 5 stocks include most blue-chip stocks in China stock market. Although the Shanghai Stock Exchange has a daily trading volume of tens of billions, it is very scattered, while foreign mature markets are different, and most of their trading volume is concentrated in blue chips. Since ETF is an arbitrage transaction, its trading volume will be concentrated in these 5 stocks.

the weight of SSE 5 index is not based on the number of circulating shares of constituent stocks, but a weighted proportion is determined according to different circulating proportions, and the weighted proportion is the maximum value of the range, and then the adjusted share capital is determined by multiplying the weighted proportion by the total share capital, which is the final weight.

Extended information:

When there is a big deviation between the market price of SSE 5ETF and the net value of fund units, investors can use the subscription and redemption mechanism for arbitrage trading.

for example, when the market price of SSE 5ETF is higher than the net value of the fund unit, the arbitrage operation method is: "purchase SSE 5ETF fund shares-sell the fund shares in the secondary market-buy the fund stock basket".

the arbitrage income is approximately equal to "(the secondary market price of the fund-the net value of the fund unit) × the number of fund shares-the transaction cost of purchasing the fund shares and selling the stock basket".
