What is portfolio rebalancing?
Updated over a week ago

A major part of setting up your 401(k) or IRA account is selecting a portfolio that meets your goals, age, risk tolerance, and time horizon. Each portfolio – whether professionally managed or custom – has a designated mix of assets based on those preferences. However, as the investments rise and fall with the market, the balance of those assets might shift over time.

For instance, if you selected Guideline’s Moderate portfolio, you would start off with a mix of 65% stocks and 35% bonds. During the year, if stocks showed strong performance, you might end up with your portfolio shifting to 75% stocks and 25% bonds.

Portfolio rebalancing helps prevent this shift and keep your assets aligned with your target allocation and goals.

How rebalancing works

Portfolio rebalancing is the process of selling shares of a particular holding that has done well, and using those funds to buy shares of a holding that has had less success to help maintain the weighting of the assets in an effort to keep them in line with your chosen target investment allocation.

How Guideline handles portfolio rebalancing

Guideline will rebalance your portfolio allocation regardless of whether you’ve selected one of our managed portfolios or have selected a custom portfolio allocation. If you are actively contributing, new contributions may be used to purchase a larger amount of holdings that are under-allocated in your portfolio due to differing returns from the various investments in your portfolio and shares will be exchanged to help maintain your desired portfolio.

Additional information regarding how Guideline handles portfolio rebalancing can be found in our Terms of Service, made available to you in your Guideline dashboard.
