Fund principal-guaranteed type is a kind of fund products. Its main feature is that it will not lose money during the investment period, and even if the market falls, it can keep the investment principal unchanged. Such funds generally adopt relatively conservative investment strategies, such as preferring bonds, money markets and stocks in related fields to ensure the relative stability of assets.

Compared with traditional equity funds, capital preservation funds have relatively stable income and relatively little risk. However, this does not mean that there is no risk in fund capital preservation. Because its main goal is to protect capital, there is basically no opportunity for high returns. In addition, some funds may charge a capital preservation fee as high as 20%, which will also have a certain impact on investors' income.

The fund capital preservation type is suitable for investors with low risk tolerance or need to ensure that the principal does not fall. For some investors who want to make short-term investments or seek high returns, it is not suitable to choose the fund-guaranteed type. However, for investors or the elderly with low risk tolerance, the fund-guaranteed type can protect assets without causing excessive losses due to market fluctuations.
