How Often Should I Rebalance My 401k?

Updated: 11/22/2018 by Financial Samurai 77 Comments

How often should I rebalance my 401kThe 401k investment vehicle is woefully inadequate for retirement. With the government capping our pre-tax contributions at $19,000 for 2010, maxing out our 401K is the very minimum we can do.

Fidelity reported the median account balance in the U.S. was only around $110,000 after reviewing their 12+ million accounts. This is after a seven year recovery in the markets!

For workers 55 years of age or older, the average balance is $143,300. These are terrible numbers. Let’s say you retire at 60 with $200,000 in you 401k and nothing else. You could only spend $20,000 a year for 10 years until you run out of money! Oh, how nice it would be to have a pension for life instead!

NOBODY KNOWS THE FUTURE, BUT EVERYBODY CAN REBALANCE

It’s important to realize that nothing goes up or down forever. The general trajectory is up and to the right thanks to inflation, but there’s always a lot of volatility in between. It’s currently a bull market in equities. Corporations are cash up and buying back stock.

That said, interest rates are going back up, oil prices are rebounding thanks to an OPEC cut, taxes may go up to 33% from 28% for millions of Americans who individually make over $112,500, and the world is uncertain about whether the new administration will be effective.

What you need to do is put your 401k’s performance in context. Always compare your year to date performance with the current 10-year bond yield. This is your risk free rate of return.

Historically, stocks have outperformed the risk free rate by around 4%. With the risk free rate currently at about 2.4%, you get an expected return of about 6.5%. With the S&P 500 doing well since 2009, investors have been rewarded. However, instead of rejoicing, we should think more carefully about mean reversion. The more we outperform historical averages, the higher the chance we run the risk of underperforming and vice versa.

Rebalancing your 401k is important because position sizes can change over time. I’m pretty sure that if you haven’t rebalanced your 401k in 6-12 months, your equities position is much higher than you probably would like. Your bond position is probably lower as well. It’s important to check in at least twice a year to make sure your investments correspond to your risk tolerance.

Once you’ve accumulated a reasonable size nut, the number one commandment to remember is to NOT LOSE MONEY! So long as you can grow at a reasonable rate above inflation, while continuing to earn active income from your job or passive income from your investments, you should be fine.

Check out this chart with the returns by asset class by decade. No asset class has had a green positive performance every single decade. This is why diversification and rebalancing is key!

401K REBALANCING THOUGHT PROCESS

1) Ask yourself if you are bullish or bearish about the future. Then explain to someone why you think the way you do. If you can explain to someone your stance in a coherent manner, you might be onto something. Just know that the general trend is up.

2) Check the latest 10 year bond yield and add on a reasonable risk premium of 4% to get an expected return. Note the risk premium is the premium return required for you to hold a risky asset. Are there any recent events such as Quantitative Easing in Japan, another Euro debt crisis, a Presidential election, or rising military conflict which would change your risk premium?

3) Compare your year to date return to your expected return (step 2). If your year to date return is above your expected return, you should begin to think about rebalancing into bonds or cash. Remember your overall outlook on the future from step 1 and make a judgement call.

4) Always ask yourself what is your risk tolerance. Will you be comfortable losing 10%, 20%, 30%? Will you be able to buy on the dip? Does losing more than 20% really freak you out? Only you will know what you are comfortable with.

5) You can check out the latest stock market earnings estimates and calculate earnings multiples if you wish. Just know that these earnings estimates are always wrong and are just catching up to whatever trend at the moment. With the S&P 500 above 2,180, its estimated P/E ratio is at 25.2X. Not cheap in a historical context.

REBALANCE YOUR 401K AT LEAST TWICE A YEAR

Proper Asset Allocation Of Stocks And Bonds By Age

It’s fine and dandy to just dollar cost average like a machine every time you get paid. Really, there is nothing wrong with that. The reason why I encourage everyone to rebalance twice a year is because it forces you to critically think about your portfolio and assess risk. If you can, inspect your portfolio every quarter.

You don’t have to make massive shifts like I did with my 401k portfolio from 80% equities down to 21% equities. You can just tweak your portfolio by a couple percentage points here and there. Maybe you might not make a big difference to your overall portfolio performance. However, what you will become is infinitely more aware about your assets, performance, and what is going on in the world if you rebalance. Enrich yourself with knowledge and opinions!

You can never lose if you lock in a gain. But, you can never win if you are never in the game either! Continue maxing out your 401K and investing in your retirement. Stay on track by following my 401K savings guide by age chart. Don’t forget that you can’t solely rely on your 401K in retirement. You’ve got to combine your 401K with your after tax savings, alternative income streams, and hopefully Social Security to have a chance at living a decent life after work. You deserve it!

Recommendation For Building More Wealth 

The best way to build wealth is to get a handle on your finances by signing up with Personal Capital. They are a free online software which aggregates all your financial accounts in one place so you can see where you can optimize. Before Personal Capital, I had to log into eight different systems to track 28 different accounts (brokerage, multiple banks, 401K, etc) to manage my finances.

Now I can just log into Personal Capital to see how my stock accounts are doing, how my net worth is progressing, and whether or not I’m paying too much in 401K fees. Their 401K Fee Analyzer is saving me over $1,700 a year due to its analysis! Finally, they recently launched their amazing Retirement Planning Calculator that pulls in your real data and runs a Monte Carlo simulation to give you deep insights into your financial future. Personal Capital is free, and less than one minute to sign up. It’s one of the most valuable tools I’ve found to help achieve financial freedom.

    Hey there FS,

    Looking for some sage advice on my 401K. I started with my current employer over a year ago and have been diligently contributing since the first paycheck. I am not in a position yet to max it out due my current financial health but have healthily been putting in 15% (including the % match from employer). My question is at what point would you suggest I look at trimming the winners. I am currently in mutual funds in the following allocation: 40% Large Cap, 20% Mid Cap, 15% Small Cap, 15% International, and 10% Bonds/Income. Also, I am 28 years old and so will not be touching this money for 30+ years, hopefully earlier though :)
    Any advice you have would be appreciated, thank you in advance.

    Hi FS,

    I read your blogs quite often since I live in the bay area as well! I will be 40 next year and my 401K is around 300K – less than your target amount. Part of the problem is my 401K asset allocation. It is 60% stocks, 40% bonds + cash. Now I want to rebalance to 80% stocks + 20% bonds. Stocks are at an all time high; bonds are getting hammered on a daily basis. Is it a good time to rebalance? Also, should I rebalance my 401K all in one shot or spread this across one or two years. My goal is long term – I don’t care how the market performs in the next year or two. What I care about it how big my 401K would be 25 years from now! I have been struggling to decide on this for the past two weeks. Any advice would be helpful! I need to “StockUp” my 401K ;-)

    When you say allocations to balance for stock and bonds. Are you talking about the actual number of shares or the dollar amount generated for stocks vs. bonds? When I look at my 401k via Fidelity they show asset allocation (stock dollars generated vs. bond dollars generated) and I was using that as my guide. Now thinking maybe you mean the actual shares of stock to shares of bonds?
    Your help here would be appreciated.
    Thank you.

    […] Rebalance your portfolio at least twice a year because your positions can change quite drastically as a percentage of your portfolio over time. If you really care about your finances, rebalancing once a quarter is probably even better. Whether you actually make some adjustments to your investment portfolio is a different matter.
