When to Rebalance
Calendar-based: rebalance annually or quarterly.
Threshold-based: rebalance when allocations drift by 5-10% from targets.
Hybrid: check periodically but only rebalance when thresholds are exceeded.
Tax-Efficient Strategies
Direct new contributions to underweight assets.
Use tax-advantaged accounts for the selling portion when possible.
Harvest losses to offset gains from rebalancing.
Consider the timing relative to holding periods.
Asset Location Matters
Hold tax-inefficient assets (bonds, REITs) in tax-advantaged accounts.
Keep tax-efficient assets (index funds, long-term holdings) in taxable accounts.
This "asset location" strategy can significantly improve after-tax returns.
