(1) Diversified investment-Through the fund, investors can indirectly participate in global financial and stock market transactions through small investments, thus expanding investment channels and making investment more flexible. (2) Get professional assistance-With the human resources of the fund and the investment experience of the fund manager, investors don't have to worry about their inexperience and avoid diversification. (3) Reducing risk-By diversifying investment and expanding investment channels, the risk of holding positions can be greatly reduced, because the fund's portfolio is rarely "dried up". (4) Reduce the handling fee and time-due to the huge investment portfolio of the fund, investors indirectly reduce the handling fee payable for diversified investment. At the same time, fund managers can also go through complicated procedures such as name change and interest transfer. (5) Strong cash-out ability-through the fund manager to maintain the activity of the secondary market, investors can sell all or part of the unit investment at any time according to personal needs and withdraw cash.
