Automated Rebalancing Is Crushing It. We Have The Stats To Prove It.

Based on a presentation given at the T3 Conference, New Orleans, March 10, 2026

Automated rebalancing—truly automated rebalancing—is possible. And it delivers lower dispersion, superior tax outcomes, and faster growth.

Before we get into the details, here's the short version:

• • 99.365%—weighted average automation rate across our client base
  • 99.998%—automation rate for our largest clients (fewer than 2 in every 100,000 trades manually adjusted)
  • 2.72%—average taxes saved or deferred per client in 2025
  • 14.7%—average per-year increase in new AUM growth for most-automated vs. least-automated firms

The data is based on our system and clients, but we're not the only automated rebalancing solution. So whatever we find simply lays the foundation for what is possible.

We've compiled the full analysis, with all charts and figures, into a downloadable ebook.

First, what do we mean by "automated rebalancing"?

"Automated rebalancing" means what it says: trades are generated without human intervention.

How automated is automated rebalancing?

We can ask: for each firm, what percentage of accounts are traded without any manual adjustment?

Across our client base, the weighted average automation rate is 99.365%. For our largest clients—the ones who most need scale—it's over 99.998%. Fewer than 2 out of every 100,000 trades are manually adjusted.

We can also apply a stricter definition: accounts traded without any form of manual review, regardless of whether trades were modified. Under this more demanding standard, trades are 97% automated on average, and 99% automated for our larger clients.

Regardless of which standard we use, these are meaningful levels of automation.

How good is automated rebalancing?

Efficiency

The efficiency case is almost self-evident, but here are the concrete numbers. Firms that automate can:

• • Implement tactical asset allocation changes across their entire book in a single day
  • Harvest losses in every account in a single day
  • Add customization to any account at zero incremental cost
  • Offer direct indexing to any client at zero incremental cost
  • Free every advisor from portfolio operations at zero incremental cost

The incremental cost of doing more: more tax optimization, more customization, more direct indexing—is zero. And the number of hours their client-facing advisors spend on any of it is zero.

Consistency

Firms that automate more manage portfolios more consistently, as measured by average forward-looking tracking error. The relationship is clear and directional: more automation, lower dispersion. No surprises there.

Tax Efficiency

This is where it gets interesting. The common assumption is that automation produces cookie-cutter outcomes—that you trade personalization and tax management for scale. The opposite is true.

Firms that automate are more tax efficient, not less. The reason is straightforward: manual intervention limits the frequency with which you can tax-manage each account. When humans are in the loop, you can only tax-manage accounts as often as your team has bandwidth. With full automation, every account receives maximum active tax management, every day. Higher frequency can mean better outcomes with no compromises.

In absolute terms, the results are striking. Across all Smartleaf clients, the average taxes saved or deferred from active tax management is 2.72% of tax-managed portfolio value—substantially more than most firms' advisory fees. One client found that taxes saved or deferred exceeded their advisory fees for 68% of accounts, rising to 90% on a dollar-weighted basis and 99% for all-equity accounts on a dollar-weighted basis.

We hear from clients that this ability to document the value of tax management, more than anything else, “closes the deal” with prospects, not because it’s a proof of value (impressive as it may be), but because it’s a proof of competence.

Do automated firms grow faster?

Automation is strongly correlated with growth. Every 10% increase in automation is associated with a 1.4% increase in AUM from new accounts. (That is, growth excluding market growth.)

Correlation doesn’t necessarily mean causation. Does automation cause growth, or do growing firms tend to automate, or are all three the result of something deeper?

We think all three connections are in place.

From conversations with clients, we hear that automation does directly lead to growth, in two obvious ways: it frees advisors to spend more time with clients and prospects, and it enables more sophisticated portfolio management.

It’s also the case that growing firms will often have more need for automation. They reach a stage where “the wheels are falling off”, which requires them to either stop growing or scale up their operations through automation.

But we believe the deeper connection between growth and automation is that automation is a pretty good indicator that a firm is ambitious and well run, and ambitious, well-run firms grow. 

What does it take to automate?

Beyond the platform itself, we see three main elements:

Model infrastructure

Models have a reputation for producing cookie-cutter solutions devoid of personalization or tax sensitivity. However, in the context of automated rebalancing that supports personalization and tax optimization, the opposite is true. When the cost of customization drops to zero, models become the infrastructure for personalization at scale, not a constraint on it. Custom allocations, product preferences, ESG and value screens, tax budgets—configured once, implemented automatically across every account, every day.

Parameterized customization

Custom asset allocations, custom product choices, tobacco screens, religious-values screens, tax budgets, tax rates—these become choices on a pull-down menu, not manual on-the-fly adjustments. Advisors configure them once; the system implements them consistently and automatically.

Centralized or outsourced execution

Specialization drives efficiency. Centralizing or outsourcing rebalancing frees client-facing advisors to spend their time where it matters—with clients and prospects, not spreadsheets.

What does this mean?

We see the increasing adoption of automated rebalancing as part of a broader shift in wealth management—away from a value proposition centered on product selection, performance, and trading, and toward one centered on financial planning, lifelong client coaching, and coordinating the activities of financial specialists like CPAs, trust and estate attorneys, and insurance agents.

Is automated rebalancing right for your firm? Probably, but not necessarily. If your value proposition is built around trading and product selection, it may not be the right fit. For everyone else, it's probably more a question of when rather than if.
