The new fund is issued by the fund company, and the investor is the share holder of the fund after purchasing it. Buying a fund is equivalent to a fund manager helping investors buy stocks or bonds. Investors can make money by buying low and selling high.

New bonds are issued by listed companies, and convertible bonds have the dual nature of stocks and bonds. In addition to earning the difference, investors can also earn some interest when investing in convertible bonds, and they can also be converted into stocks during the conversion period.
