Most investors lose not to bad assets but to themselves. The gap between a fund's reported return and what the average investor in that fund actually receives is well-documented and consistently wide — investors buy after gains and sell into losses, which means they hold the expensive shares and abandon the cheap ones. A lower return you can hold beats a higher one you abandon, because the return you abandon pays you nothing. The math of compounding is simple. What breaks it is the month the account is down and the news is loud and the cursor finds its way to "Sell."
A lower return you can hold beats a higher one you abandon, because the return you abandon pays you nothing.

Say the drop already happened. Félix Orban is sitting with a portfolio that is down eighteen percent, looking at what he sold two months ago when it was down nine. The question now is not whether selling was rational then. It is what the review reveals about the portfolio he should build going forward. Not the most aggressive allocation he can tolerate in a good month. The one he can hold in a bad quarter without touching it. That is the real number. The ceiling is not set by expected return. It is set by how much red on a screen he can watch without moving the cursor.
Most people discover their actual risk tolerance after a loss, not before. The account statement is honest about this in a way the intake questionnaire never was. What it shows you is worth keeping.
