Rebalancing Keeps the Portfolio Aligned With the Goal

Some assets grow faster than others, and rebalancing pulls the plan back toward the risk level you originally chose.

Why this lesson matters

Some assets grow faster than others, and rebalancing pulls the plan back toward the risk level you originally chose.

The core idea

• Over time one asset can become too large a share of the portfolio and quietly change the overall risk level.
• Rebalancing means returning to the allocation that fits your goal, time horizon, and risk tolerance rather than punishing the asset that performed well.
• You can rebalance by directing new money toward the underweight part or by trimming the overweight part carefully.

Practical example

If equities rise far above their original target weight, new contributions or selective trimming can bring the portfolio back toward plan.

Common mistakes to avoid

• Letting winners keep expanding without review
• Treating rebalancing as constant trading
• Ignoring fees and tax impact before adjusting

What to do next

It keeps the plan disciplined when some holdings grow faster than others instead of letting risk drift higher unnoticed.

Important caution

Rebalancing is not a daily activity; overdoing it can raise costs and distract from the goal.
