When you say it’s done well vs the index, what do you mean?
Because the fact sheet you linked says it failed to beat the index in 2017, 2018, 2019, 2020, 2021, 2023 and 2024.
It’s underperformed vs the index by over 3% per annum in the last 5 years and since inception.
It dropped by twice the index drop in 2018 and gave negative returns in 2020.
It has the same volatility as the index, and a bigger drawdown in its worst month in the last 5 years (-18.6% vs -15.8%)
None of that is to say it’s a fund that doesn’t suit specific purposes as it may well do, but curious on how you’re measuring doing well!
