What is a unit?

A unit is what you buy when you invest in a fund – it’s your slice of the overall investment. Instead of owning individual shares or bonds, you own units in a fund that itself could hold a mixture of shares, bonds, or other assets and investments.

The value of a unit goes up or down depending on how the investments inside the fund are doing. If the fund performs well, each unit becomes more valuable.

It’s a bit like buying a slice of cake – your unit is one slice, and the whole cake is the fund. The more units you have, the bigger your share of the fund’s potential returns.
