Your money is invested into the funds that you choose when you select an investment from our comparison tables. The manager of each fund then invests directly in the shares and bonds of individual companies.
Fund managers can do this much more cheaply than you could yourself because they are dealing with millions of pounds within the fund. They can also spread the fund's money over lots of different investments which helps reduce the risk.
Our comparison tables help you compare the funds (and portfolios of funds) available from all different managers and choose the ones with the lowest charges and highest projected returns.
