The possibility that liquidity risk will lead to theoretical loss. Although we generally regard the money fund as a risk-free wealth management product, there have also been short-term losses of the money fund in history. On June 8, 2006, TEDA ABN Amro Monetary Fund showed negative income, and the income per 10,000 funds announced that day was -0.2566 yuan; But the next day, the fund's income returned to positive. On the same day, the E Fund's income per 10,000 shares also showed a negative value, and it also returned to a positive value on June 12. This happens because it coincides with the intensive issuance period of new shares. Because the yield of new shares is much higher than that of the cargo base, there was a huge redemption of the cargo base that day. In order to cope with large-scale redemption, fund managers have to sell their bonds. At this time, when the bond market was depressed, there was a loss.
