The best portfolio is the one you can actually hold
Two things are commonly conflated: how much volatility a plan can mathematically absorb, and how much volatility a person can live through without abandoning the plan.
The second is the binding constraint. A theoretically optimal allocation that gets sold in a downturn produces worse outcomes than a more conservative one that survives it intact.
This is why the useful question is behavioural rather than numerical — what someone actually did in a prior decline is more informative than what they say they would do in the next one.
Alignment between the two is the goal. Neither an unnecessarily cautious portfolio nor an unsustainably aggressive one is free.
