The FMP Mutual Funds endpoint provides a list of all the mutual funds that are registered with the Securities and Exchange Commission (SEC). This information can be used by investors to identify potential investment opportunities. For example, an investor who is interested in investing in the technology sector may want to browse the list of mutual funds that track the S&P 500 index. Investors can also use the mutual funds endpoint to compare different mutual funds. For example, an investor may want to compare the expense ratios of different mutual funds to find the one that is most cost-effective.
