The rate of return in capital preservation funds is generally around 3%, and it can reach about 5% in some long-term (more than two years) capital preservation funds.
The capital preservation fund mainly invests most of its principal in investment instruments with fixed expected returns, such as time deposits, bonds, bills, etc., so that the due principal plus interest is roughly equal to the principal invested at the beginning. Therefore, under normal circumstances, unless the issuer goes bankrupt and liquidates, it will affect the payment of the principal, which is basically in line with the safety of investors.
