Why smooth average returns hide ugly paths

Part of: Risk vs Return

risk and return: long-run average returns do not show the path. Fees, your start date, and when you withdraw cash all change the outcome.

Headline vs reality

For risk and return, early losses weigh heavily if you are withdrawing; annual fees shrink balance every year. Risk vs Return separates average return from those mechanics.

Mechanics

Historical index averages do not tell you which year you retire or which years you sell; sequence of returns and fee drag still apply to risk and return.

Concrete case

Same savings rate: starting five years earlier often beats chasing a slightly higher return starting five years later, because more contributions compound longer.
