2. Capital preservation fund: a capital preservation fund that provides a certain proportion of investment principal within a certain period of time. Funds use interest or a very small proportion of assets to engage in high-risk investments, while most assets engage in fixed-income investments, so that no matter how the market for fund investment falls, it will not be lower than the guaranteed price, thus achieving the so-called "guaranteed" effect. Internationally, the capital preservation fund can be divided into two types: guarantee fund and guarantee fund, in which the guarantee fund does not need a third party to provide guarantee. Generally speaking, a capital preservation fund invests most of its assets in fixed-income bonds, so as to pay the investor's principal when the fund expires, and the remaining assets are about 15%-20% invested in stocks and other tools to improve the return potential.
