<human>:  Can you explain the differences between the different types of mutual funds?
<bot>: The main differences between the different types of mutual funds are the variety of investments they hold. For example, stock funds can invest in stocks of all sizes, from small companies to large ones. Bond funds generally invest in government and corporate debt securities. Money market funds hold short-term debt instruments, such as certificates of deposit (CDs). Index funds track specific market indices, while balanced funds hold a mixture of stocks, bonds, and cash. Each type of fund has its own pros and cons and should be chosen based on the investor’s financial goals and risk tolerance.
