Your portfolio changes constantly — even when you do nothing. Stocks rise, bonds fall, gold moves sideways. After a year, your 60/40 portfolio can suddenly be 75/25. Rebalancing brings it back into balance.

What Is Rebalancing?

Rebalancing is the regular adjustment of your portfolio weighting back to the target allocation. If your stocks have risen from 60% to 70%, you sell 10% of stocks and buy bonds — restoring the original weighting.

Why Is Rebalancing Important?

Risk control: Without rebalancing, your portfolio becomes increasingly stock-heavy. Your risk rises imperceptibly.
Contrarian action: Rebalancing forces you to sell high and buy low. Exactly the opposite of what most people do emotionally.
Return boost: Studies show rebalancing can improve risk-adjusted returns by 0.5-1% per year.

3 Rebalancing Strategies

1. Calendar-Based

Once per quarter or once per year — on a fixed date. Simplest approach.

2. Threshold-Based

Rebalancing triggered when an asset class deviates more than 5% from target. Example: Stock target 60%, rebalance when below 55% or above 65%.

3. Cash-Flow Rebalancing

Instead of selling, direct new deposits into underweight classes. Tax-free and cost-free — the most elegant solution for savers with regular deposits.

Practical Example

Target: 60% stocks, 30% bonds, 10% gold. After 6 months: 68% stocks, 24% bonds, 8% gold.

Rebalancing action on 50,000 euro portfolio: Sell 4,000 stocks, buy 3,000 bonds, buy 1,000 gold.

Tax Considerations

Rebalancing through selling triggers capital gains tax. Optimization: pair with loss harvesting, use tax-free allowances, prefer cash-flow method.

Automated Rebalancing

Robo-advisors rebalance automatically. At the Dieter Dashboard, you can set rebalancing alerts: notifications when a class deviates more than 5% from target.

Bottom Line: Rebalancing is the simplest method to systematically sell high and buy low. It costs 30 minutes per quarter — and improves your returns at reduced risk.
