Use Rebalancing Rules

Describe how to rebalance a portfolio back to target allocations after market movements — without chasing recent winners — and explain why this discipline reduces risk and enforces the original investment plan.

In this lesson

Use Rebalancing Rules is part of Building Wealth Across Life Stages. This preview shows how wealth-building connects to everyday family decisions such as earning, saving, spending choices, goals, approvals, or parent-guided money conversations inside Progress Penguin.

Think about this money choice

Sade's portfolio drifted from her target asset mix after a strong stock market year. She wants to rebalance but is tempted to put even more into what has been performing well.

How it works

After a strong market year, a portfolio's equity allocation grows relative to bonds and other assets — drifting above the target. Rebalancing restores the target mix by selling equities and buying underweighted assets. The temptation at this point is to leave equities overweighted because they have been performing well — but this increases the portfolio's risk and concentrates it in the recent winner. Rebalancing imposes the discipline of selling strength and buying weakness.

Apply it to a real decision

Real-life money moment: Sade's target is 65% equities and 35% bonds. After a strong stock market year, equities have grown to 80% of her portfolio and bonds to 20%. To rebalance: sell equities worth 15% of the portfolio and buy bonds. The temptation: leave equities at 80% because they have been doing well. The risk: an 80% equity portfolio experiences a 25% market fall. Loss on the drift portfolio: 20% of total value. Loss on the rebalanced 65/35 portfolio: approximately 16% of total value. The rebalance reduced the loss by 4 percentage points.

Quiz preview

Using rebalancing rules means:

Checking daily and rebalancing whenever any asset moves by more than 1% from target

Never rebalancing since frequent trading costs more than any allocation benefit provides

Setting a trigger — like a 5% drift from target — that initiates a portfolio adjustment

Rebalancing only when the market has fallen by 10% since that represents a buying opportunity

Your target is 60% shares and 40% bonds. Shares rise to 68%. Your rebalancing rule triggers at 5% drift:

Yes — 8% drift exceeds the 5% trigger so you sell some shares and buy bonds

No — 8% drift is within normal market movement and does not require action

No — rebalancing rules only apply to falling assets not to rising ones

Yes — but sell all shares and move everything to bonds since equities are clearly overvalued
