How to rebalance your portfolio without selling
Use new contributions to buy underweight holdings instead of triggering taxable events. Here's how to set it up.
Why avoid selling?
Every time you sell a position in a non-registered account, you potentially trigger a capital gain. Even if it's a small rebalancing trade, you're creating a taxable event that you'll need to report — and pay tax on — in the current year. Over time, this erodes your compounding returns.
The alternative is contribution-based rebalancing: instead of selling overweight positions, you simply direct new cash toward whatever is underweight. Your portfolio gradually realigns without a single sell order.
How contribution-based rebalancing works
The math is straightforward. At any given moment, some holdings are above their target weight and some are below. When you have cash to invest, you calculate which positions are furthest below target and buy those first.
For example, if your target is 40% VTI and you're currently sitting at 35%, and you have $1,000 to invest, you'd direct some or all of that toward VTI before buying anything else. Repeat this every contribution and your allocation slowly converges on your targets over time.
The catch: it works best with regular contributions
This strategy is most effective for investors who contribute on a regular cadence — monthly, bi-weekly, or quarterly. The more frequently you're adding money, the faster your portfolio rebalances passively.
If you invest infrequently or in lump sums, large drifts may require a hybrid approach: use contributions for smaller corrections, but accept that occasional selling may be needed after significant market moves.
Setting it up with Wealth Rebalancer
In Wealth Rebalancer, set a target weight for each holding in your portfolio. When you're ready to invest, open the Rebalancer, enter your contribution amount, and the tool calculates exactly how much to buy of each position to move your allocation closer to target.
You don't have to do the math manually. The rebalancer accounts for your current weights, your targets, and your contribution size — and gives you a clean list of buy amounts to act on.
A simple rule to follow
For most investors, a contribution-based approach handles 80% of rebalancing needs. Reserve selling for situations where a position has grown so overweight that contributions alone can't close the gap within a reasonable timeframe — typically when a single holding has drifted more than 10 percentage points above target.
