Portfolio Rebalancing: Calendar and Threshold Approaches
Understand calendar-based and threshold-based rebalancing without a universal interval, drift trigger or trade instruction.
Quick answer
EstimateRebalancing means reviewing or changing holdings in relation to a portfolio policy. It can involve contributions, withdrawals or trades.
Rebalancing means reviewing or changing holdings in relation to a portfolio policy. It can involve contributions, withdrawals or trades.
Comparison factors
- The chosen portfolio policy and target ranges
- Taxes, exit loads, spreads and transaction costs
- Cash flows available for adjustment
- Liquidity and account restrictions
- Whether the change reflects drift or a changed goal
How to use the comparison
Rebalancing can be calendar-based or threshold-based. The trigger depends on the policy the investor has chosen; no interval or drift percentage is universal.
Illustrative scenario
Illustrative scenario: new contributions may reduce a policy drift without selling. A trade may create different costs, so the two paths are compared rather than ranked.
Common interpretation errors
- Treating annual rebalancing as mandatory
- Using one drift threshold for every portfolio
- Trading without checking costs and tax consequences
Next step
Document the policy, trigger and cost checks before acting on drift.
