The retirement risk zone represents a fragile period in the financial life cycle of people in defined-contributions superannuation. It primarily affects people of middle means. Sequencing risk has been described as an independent risk, but it has largely been a consequence of the dominant asset allocation strategy, described here as aggressive constant-mix. Lifetime glide paths should instead resemble a displaced V: the share of growth assets should fall by something like 20-50 percentage points over working life, then another 5 or 10 percentage points on the day of retirement, but should subsequently rise through retirement, by something like 20-30 percentage points.
