Sequence of returns

Same average return, different order, very different outcome when money is withdrawn

The idea

With no withdrawals, the order of returns doesn't change the ending value. Once money is being taken out each year, bad years early do more damage, because withdrawals lock in the losses before the recovery.

Example

Two 30-year runs with the same average return can end with very different balances if one starts with a crash and the other ends with one.
