Investment funds are baskets of securities chosen because of their growth prospects by asset management companies that are experts in financial markets. These funds work on a co-ownership basis: when you invest in a fund, you acquire ownership that corresponds to a share of a basket of equities or bonds already selected and actively managed by experts. This means investing in funds can feel safer than buying individual securities, particularly for a novice. Moreover, investment funds tend to have variable capital, which allows you to trade in your securities on a secondary market at any given moment. The funds can take several legal forms, such as the Société d’Investissement à Capital Variable (SICAV) and the Fonds Commun de Placement (FCP). There are three broad categories of fund: passively managed investment funds, actively managed investment funds and hedge funds.
