Can I rebalance the asset allocation in my VT529 account?

No, you cannot rebalance the asset allocation in your individual portfolio(s), but you can tweak your overall investment options up to twice a year. There are two ways to adjust how your money is invested: either by selling your portfolio and using those funds to purchase a new one, or by keeping your previous portfolio(s) and then putting future contributions into a new investment option.
