first, from the perspective of risk, because the interest rate and investment direction of bonds are basically fixed at the time of issuance, the risk is relatively small; Because of the high liquidity and the great influence of policies, markets and other factors, the stock has high solid risk; The fund depends on which type of fund it belongs to, where it invests. Monetary fund has the smallest risk, followed by capital preservation type, bond type and stock type with the greatest risk. Second, low income risk leads to low income, while high risk leads to high income. Third, liquid monetary fund has strong liquidity because it has no closed period. Other new funds generally have a closed period, and it will be fine when it is redeemed; The liquidity of stocks is strong, but there is a risk of being quilted if investment losses occur; Bond type is generally fixed term, which is poor in liquidity.
