The so-called primary market buying means that when the fund company issues this product, you subscribe, or you can subscribe after the issuance period. Then selling is redemption from the fund company. Ordinary investors can purchase or redeem fund products through bank consignment channels. There are no special conditions. It seems that the primary market can subscribe for 1000 yuan. You can confirm this when you buy it My understanding is that if it is not traded in the secondary market, it can be operated as an ordinary index fund.

Of course, it is recommended to buy through online fund supermarkets (Tian Tian Fund Network, He Xun and the like), which is cheaper and has an intuitive comparison with similar products. A basket refers to all the stocks in the index fund, which are allocated according to the weight ratio when compiling the index. For example, each Shanghai and Shenzhen 300 is equal to 1 share of PetroChina +2 shares of China Merchants Bank+1.5 shares of CITIC Securities ... for example, it is not necessarily the stock and proportion I said.
