Your 401(k) is not something you should simply set up once and forget about forever. As markets change and investments grow at different rates, your portfolio allocation can slowly drift away from your original retirement strategy. That’s where rebalancing comes in.
At Top 401(k) Providers, we help individuals better understand retirement planning and how to make smarter long-term financial decisions. One important habit many investors overlook is regularly reviewing and rebalancing their retirement accounts.
What Does Rebalancing a 401(k) Mean?
Rebalancing means adjusting your investment allocations back to your intended target percentages.
For example, let’s say your original 401(k) allocation looked like this:
- 70% stocks
- 30% bonds
If the stock market performs well over several years, your portfolio might shift to:
- 82% stocks
- 18% bonds
While growth is exciting, your account may now carry more risk than you originally intended. Rebalancing would involve moving investments around to restore your desired allocation.
Why Rebalancing Matters
Over time, failing to rebalance can expose your retirement savings to unnecessary risk.
Rebalancing helps:
- Maintain your intended risk level
- Keep your investment strategy aligned with your goals
- Prevent overexposure to one asset class
- Encourage disciplined investing
- Reduce emotionally driven investment decisions
Many investors unknowingly become too aggressive during strong markets or too conservative after downturns.
How Often Should You Rebalance?
There is no universal rule, but many financial professionals suggest reviewing your 401(k):
- Once per year
- Every six months
- After major market swings
- When allocations drift significantly
A common strategy is to rebalance when an asset class shifts more than 5% from your original target allocation.
For example:
- Target stock allocation: 70%
- Current allocation: 76%
- Difference: 6%
That may signal it’s time to rebalance.
Can You Rebalance Too Often?
Yes. Constantly adjusting your portfolio based on short-term market movements can sometimes hurt long-term performance.
Frequent rebalancing may:
- Increase transaction costs in some accounts
- Trigger emotional investing behavior
- Lead to overreacting during market volatility
Retirement investing typically works best with a long-term strategy and consistent contributions over time.
Target-Date Funds Automatically Rebalance
Many 401(k) plans offer target-date funds, which automatically adjust and rebalance investments as you get closer to retirement age.
These funds are designed to:
- Become more conservative over time
- Reduce risk gradually
- Simplify retirement investing
- Provide hands-off portfolio management
For some investors, target-date funds can make retirement planning easier and less stressful.
Other Times to Review Your 401(k)
In addition to regular rebalancing, you may want to review your retirement account after:
- Changing jobs
- Receiving a salary increase
- Approaching retirement
- Major life changes
- Market downturns
- Rolling over an old 401(k)
Retirement planning should evolve alongside your life and financial goals.
Don’t Forget About Fees
While reviewing your 401(k), it’s also smart to evaluate:
- Expense ratios
- Administrative fees
- Investment performance
- Employer match opportunities
- Available fund options
Even small fees can significantly impact retirement savings over decades of investing.
Final Thoughts
Rebalancing your 401(k) is an important part of maintaining a healthy long-term retirement strategy. While markets naturally fluctuate, keeping your portfolio aligned with your goals can help manage risk and support more consistent retirement planning.
The key is staying proactive, reviewing your investments regularly, and focusing on long-term financial growth rather than short-term market noise. Schedule an appointment with one of our advisors, here!
