Funds have broad and narrow definitions. A fund in a broad sense refers to a certain amount of funds set up for a certain purpose. It mainly includes trust and investment funds, provident funds, insurance funds, retirement funds and funds of various foundations. It should be noted here that what people usually refer to as funds mainly refers to securities investment funds, that is, stock funds, but there are actually many non-stock funds.
