Understanding Portfolio Rebalancing

Why Rebalance?

Over time, strong-performing assets grow to represent a larger portion of your portfolio, increasing risk. Rebalancing sells winners and buys underperformers to maintain your target risk level and enforce disciplined investing.

When to Rebalance

Common strategies include calendar rebalancing (quarterly or annually) and threshold rebalancing (when any asset drifts 5%+ from target). Threshold rebalancing reduces unnecessary trades while keeping portfolios aligned during volatile periods.

Rebalancing Methods

You can rebalance by selling overweight positions and buying underweight ones, or by directing new contributions to underweight assets. The latter approach minimizes transaction costs and tax implications in taxable accounts.

Tax Considerations

Rebalancing in taxable accounts triggers capital gains. Consider rebalancing in tax-advantaged accounts (401k, IRA) first, or use tax-loss harvesting to offset gains. New contributions can rebalance without selling appreciated assets.

Rebalancing Bands

Setting tolerance bands (e.g., 5%) prevents over-trading. If your 60% stock allocation drifts to 63%, you may not need to act. But if it hits 67%, rebalancing becomes important. Wider bands reduce costs; narrower bands maintain tighter control.

Costs vs. Benefits

Frequent rebalancing incurs transaction costs and potentially taxes. Research suggests annual or threshold-based rebalancing provides most benefits while minimizing costs. Use this rebalancing simulator calculator to model different scenarios before acting.
