Automatic rebalancing is a feature in some investment accounts that helps keep your portfolio aligned with your target mix of investments, like stocks and bonds. Over time, certain investments may grow faster than others, causing your portfolio to drift from your original plan. With automatic rebalancing, the account adjusts your holdings at regular intervals—usually by buying or selling portions of investments—to bring everything back to your chosen balance. This helps manage risk and keeps your investments in line with your goals, without needing you to make changes manually.
