Among them, the fund has the best liquidity. Except for closed-end funds that cannot be redeemed at any time, most of them can be purchased or redeemed at any time (that is, they can be realized at any time). Generally, trusts lend money to companies in need. Only trust companies operate, set up trust plans, and repay funds and benefits when due. Funds are the most flexible. Leasing should refer to financial leasing, but it is also a loan relationship. Factoring mostly accepts those bills (bank acceptance bills, commercial bills) that are not due, and the income is relatively low.
