Well, if you have enough, then you could indeed simply consider ring fencing it in a bucket of asset protectors.
At the same time though, all fresh money over the next 10-15 years could then be invested into another bucket with a higher risk threshold. That could then be derisked for retirement part 2.
Retirement income 'assured', but with FOMO scratched with bucket2.
It may also help the discipline of leaving Bucket1 alone and not being tempted to disturb it with tomorrow's Peloton. If you need help with the discipline, that is. (I did).
By separating into buckets, perhaps half the final retirement pot will have a new 15 year period in which to try for growth.
Who knows? At retirement, you could have lots of options. Live off the whole lot, live off bucket1 for 15 years, derisk the next wodge and use that for years 15-30. Or see how it's working out after a period, then blow bucket2 on whatever.
At worst, maybe it just bolsters the common wealth and makes the whole retirement easier.
It all depends on a lot of things, but personal psychology matters a lot. Some say that too few equities is as much a long term risk as too few, and we all have to find a way to live with that.
Hindsight is not terribly helpful, but a lot of the 10 years I spent approaching retirement, when I started to take an interest, was for the most part a time of daily 'wall of worry' type headlines, with doomsayers on CNBC sucking teeth and shaking heads. It would have been far too easy to miss out. Having said that....who knows?
The best advice I remember was 'time in the market, not timing the market'. The time parameter is set by when you need the wealth, so a graduated sequence of target dates may help?
No advice!. Just the sort of thing I was mulling over then.
