Rebalancing Plan
Portfolio rebalancing brings your actual asset allocation back in line with your target allocation.
Core formula for each asset:
Target Value = Total Portfolio × (Target % / 100)
Difference = Target Value − Current Value
- Positive = Buy more
- Negative = Sell some
Why rebalance?
- Keeps your risk level consistent with your goals
- Forces you to “buy low, sell high” systematically
- Prevents any single asset from dominating your portfolio
Example: If your target is 60% stocks / 40% bonds and your portfolio has grown to 70% stocks / 30% bonds:
- Sell some stocks and buy bonds to return to 60/40
Common rebalancing schedules:
- Calendar-based: Quarterly or annually
- Threshold-based: When any asset drifts more than 5% from target
- Combination: Check quarterly, rebalance if threshold exceeded
