Since the minimum subscription and redemption unit of ETFs in the primary market is generally 1 million fund shares, while the trading unit in the secondary market is only 100 fund shares, ordinary investors cannot buy them in the primary market.

In order to broaden the sales channels of ETFs, some fund companies have developed ETF-linked funds. The subscription and redemption methods and channels are exactly the same as ordinary open-end funds. Generally, retail investors can buy ETF-linked funds, and the starting point is also 1,000 yuan.
