Mirror funds are usually set up by insurance companies as investment choices for their offshore investments / savings plans. For a selected fund managed by other fund managers, the insurance company set up its own fund, the mirror fund, which invests exclusively in the underlying fund. A mirror fund may hold a proportionately small amount of cash. A mirror fund is usually priced independently of the underlying funds. However, the performance of a mirror fund will move mainly in line with the underlying fund.
The insurance company can offer a service to their clients by providing access to the underlying funds without entry or exit charges, and switching in and out of these funds is possible at any time and with no charge.
Investments can be spread world-wide via one investment company and vehicle, one can easily move out of funds that do not perform in the short term which dramatically can increase the growth of your investment.
