Rebalancing: The Unglamorous Habit That Controls Portfolio Risk

Why target allocations drift over time, and simple approaches to resetting them.

As different assets grow at different rates, a portfolio's actual allocation drifts away from its original target — a strong year for equities can leave a portfolio far more stock-heavy than originally intended.

Rebalancing resets the allocation back to target, which mechanically means trimming winners and adding to laggards — a discipline that runs against natural behavioral instincts.

Common approaches include calendar-based rebalancing (e.g., annually) or threshold-based rebalancing (when an allocation drifts beyond a set percentage), each with different tax and cost implications.
