An open-ended investment company (OEIC) is a professionally managed listed company which purchases shares in other financial assets or companies. When you purchase shares in an OEIC, the OEIC fund manager pools your money with that of other investors. This allows individual investors access to a greater variety of financial assets.
The value of an OEIC is directly linked to the performance of its underlying investments. As the value of the underlying investments increase, so do the value of the shares purchased.
