It can be said that buying index funds is a convenient and quick investment method. Growth enterprise market, also known as the second board market, is dominated by high-tech enterprises. Although there is a temporary lack of performance, there is ample room for growth. Buying GEM funds is higher than most broad-based index funds in terms of growth. There are still many channels to buy GEM funds. We can buy through Alipay, mobile banking and securities software. Alipay: After opening Alipay, directly search for funds in the search bar above, enter the fund page and search for GEM, and you will see many index funds about GEM. Mobile banking: Find financial options in the mobile banking client, and search for GEM funds after entering the financial management page. Take China Merchants Bank as an example, the purchase steps are as follows: Enter GEM funds in the financial search bar and select the funds to buy. Securities software: The software of major securities companies has fund options. After clicking in, we can search for GEM funds, and then click Buy to complete the subscription. The difference between Alipay, banks and securities software to buy GEM funds: Generally speaking, the varieties of index funds purchased through Alipay and securities software should be more flexible, and investors can purchase or redeem them flexibly. The capital limit is low, with a minimum of 10 yuan, which is suitable for investors with strong autonomy; GEM funds subscribed by mobile banking clients generally have an investment period, and investors cannot redeem them at will.
