When to Use
- Deciding when and how to rebalance a portfolio back to target weights

- Managing rebalancing across taxable and tax-deferred accounts
- Using cash flows (contributions/withdrawals) to rebalance opportunistically
- Evaluating the rebalancing premium and its contribution to portfolio returns
