Investment performance
We measure the Fund's investment performance in two ways:
- relative to the NZ 90 day Treasury Bill return — the reward for taking market risk
- relative to a passive reference portfolio benchmark — the value added by the Guardians' active management.
Given our long-term mandate, we expect to return at least the Treasury Bill return + 2.8% over any 20-year moving average period. This is our long-term performance expectation.
The below graph shows how the first dollar invested in the Fund has grown over time, versus our Reference Portfolio and Treasury Bill benchmarks.
