Our take
Structural notes on how this fund behaves. Read our guide on the 6 warning signs.
Buffer ETF — downside protection at a cost
Defined-outcome funds cap upside (typically 8–20%) in exchange for partial downside protection (9–30%), priced via options. Fees are materially higher than the underlying index (often 0.70%+ vs 0.03–0.10%). For most pre-retirees, a simple stock/bond mix achieves similar downside behaviour at a fraction of the cost.
