An active fund is an investment that aims to do better than a set standard called a benchmark. People who manage the fund make choices to try and earn more money than this standard.
A passive fund tries to copy the standard, not beat it. This usually makes passive funds cheaper than active funds. However, passive funds are less likely to earn much more money than the standard.
Cushon offers both types of funds so you can combine your pensions in a way that suits your savings and investments.
