FOF fund is a fund that invests in other funds. In China, FOF started late. At present, most FOFs circulating in the market are products issued by brokers or some private FOFs. However, from 2065438 to September 2006, the CSRC issued the document "Guidelines for the Operation of Public Offering of Securities Investment Funds No.2-Guidelines for Funds in Funds", which standardized the establishment of public offering FOF and officially kicked off the era of public offering FOF.

At present, the investment threshold of FOF in the market is relatively high, ranging from 1 10,000 to110,000,000, but the investment scope is all over the world, involving stocks, bonds, currencies and other funds, which can not only realize global asset allocation, but also form various types of FOF, which can meet investors with different risk preferences. With the development of public offering FOF, it is believed that in the near future, it will bring more investment opportunities to investors.
