Portfolio Rebalancing: A Frequently Overlooked, Yet Powerful Investing Strategy
In the world of investing, some strategies get all the attention, such as stock picking, tax savings, or chasing the next big trend. One powerful and often overlooked tool available to investors is portfolio rebalancing.
While it may not be flashy, portfolio rebalancing can play a critical role in managing risk, trying to improve long-term outcomes, and helping investors stay aligned with their financial goals. Let’s break down what portfolio rebalancing is, why it matters, and how to use it effectively to help you build financial confidence.
What Is Portfolio Rebalancing?
At its core, portfolio rebalancing is about maintaining your intended investment mix over time. Let’s say your portfolio is structured to hold:
- 60% stocks
- 40% bonds
Over time, markets move. Stocks might surge while bonds lag, or vice versa. Without intervention, your portfolio could drift to something like 70% stocks and 30% bonds. With portfolio rebalancing, you’re adjusting your investments back to your original target allocation.

Why Rebalancing Is Essential
1. Markets Are Unpredictable
Markets don’t move in straight lines; they fluctuate constantly. In just a short period, stocks can swing dramatically:
- Down nearly 20% in a month
- Up, down, and back up again within the same year
Without a plan, investors can become reactive and make emotional decisions. Rebalancing your investment mix creates discipline, helping you stay proactive instead of reactive.
2. It Keeps Risk in Check
Over time, higher-performing assets (like stocks) naturally take up a larger share of your portfolio. That can increase your exposure to risk, potentially without you realizing it. Rebalancing may help to:
- Prevent overexposure to volatile assets
- Keep your portfolio aligned with your risk tolerance
- Especially protect investors nearing or in retirement
In short, it’s less about boosting returns and more about controlling risk.
3. It Enforces “Buy Low, Sell High”
Rebalancing forces a simple but powerful behavior:
- Sell portions of assets that have grown (locking in gains)
- Buy assets that have lagged (potentially at lower prices)
This systematic approach removes emotion from investing decisions and reinforces long-term discipline.
Portfolio Rebalancing Strategies
1. Threshold (Parameter-Based) Rebalancing
Set a tolerance range, such as ±5% from your target allocation. For example, if stocks move from 60% to 65%, you would rebalance back to 60% stocks to keep your portfolio continuously aligned.
This approach is sometimes called the 5/25 rule: rebalance when an asset class drifts more than 5 percentage points, or 25% of its target weight, from its original allocation.
Both threshold rebalancing and time-based rebalancing (which we’ll cover next) can be done manually or automatically.
2. Time-Based Rebalancing: How Often Should You Rebalance Your Portfolio?
You can also review your portfolio at set intervals, such as annually or quarterly. Annual rebalancing often captures most of the benefits without excessive trading. Quarterly rebalancing involves more frequent oversight.
3. Ongoing Contributions (for Accumulators)
If you’re still investing regularly, adding funds strategically can help rebalance without selling assets.
The Hidden Advantage of Tax Loss and Tax Gain Harvesting
Rebalancing your investment mix isn’t just about allocation. It can also unlock meaningful tax benefits. Our CFAs and other investment specialists frequently work in tandem with our CPAs and other tax specialists, as well as our advisors and other planning specialists, to help build connected financial plans.
Tax Loss Harvesting
Tax loss involves selling investments at a loss. Use those losses to offset gains or reduce taxable income or reinvest in similar (not identical) assets to maintain exposure. It’s important to note that you must avoid repurchasing the same investment within 30 days to comply with IRS guidelines.
Tax Gain Harvesting
Tax gain harvesting involves the selling of appreciated assets in taxable accounts to take advantage of lower tax rates. When markets recover, gains can be realized strategically and previously harvested losses can offset those gains. This strategy may help improve after-tax investment outcomes by managing tax consequences more efficiently.*
Roth Conversion Opportunities
Market downturns can also create tax planning opportunities:
- Convert traditional IRA assets to a Roth IRA when values are lower
- Pay taxes on a reduced amount
- Allow future growth to occur tax-free
Roth conversions can potentially turn volatility into a long-term advantage. However, there are various pros and cons to doing Roth conversions. Consult with a tax professional prior to doing any Roth conversions so that you’re aware of the opportunities and unintended consequences that may apply.
The Bigger Picture: Portfolio Rebalancing Is About Discipline
Rebalancing works best when it’s part of a broader financial plan that includes:
- Risk management
- Tax strategy
- Long-term allocation goals
Without a plan, many investors tend to rely on emotions, primarily fear and greed, which often leads to poor timing and missed opportunities.
Three Mistakes to Avoid
1. Trying to Time the Market
Missing even a small number of the market’s best days can drastically reduce returns. Stay invested and disciplined instead.
2. Ignoring Tax Opportunities
Market downturns aren’t just losses, they’re opportunities for:
- Tax loss harvesting
- Strategic conversions
Failing to act may leave significant value on the table.
- Letting Portfolios Become Too Concentrated
Overexposure to a single sector or stock increases risk dramatically. Diversification and consistent rebalancing may help to prevent this.
