Financial planners recommend you rebalance at least once a year and no more than four times a year. One easy way to do it is to pick the same day each year or each quarter, and make that your day to rebalance.

Is rebalancing your 401k good?

There is a good reason for the importance of rebalancing a portfolio is emphasized. Not only does rebalancing allow you to buy your stock mutual fund and bond fund shares at a lower price, but it also forces you to sell at a higher one. Rebalancing may also boost your investment returns by a quarter percent or more.

How often should you rebalance?

You can either rebalance your portfolio at a specific time interval (say, yearly), or you can rebalance only when your portfolio becomes clearly unbalanced. There's no right or wrong method, but unless your portfolio's value is extremely volatile, rebalancing once or twice a year should be more than sufficient.
