Model portfolios have helped many advisors solve for scale. The next challenge is more nuanced: how do advisors keep that scale while delivering more personalization, tax awareness and differentiated value to clients?

That was the central theme that stood out to me during a recent webcast hosted by RIA Channel with WisdomTree and Quorus. The polling results from advisors were especially telling. They did not suggest that advisors are rejecting models. Quite the opposite. They suggested that the model portfolio conversation has entered its next phase.

When asked how they currently implement portfolios, roughly 37% of advisors said they primarily use model portfolios, while another 35% said they use a mix of models and SMA strategies or direct indexing.¹

To me, that means models are no longer a niche implementation tool. They are becoming core infrastructure for modern advisory practices.

But infrastructure alone is not enough.

When advisors were asked where model portfolios fall short, the top response was limited tax awareness and after-tax optimization at 38%. Other common responses included the inability to tailor portfolios to specific client needs and difficulty differentiating the advisor’s value proposition, both around 31%.²

That gets to the heart of the issue. Advisors like the efficiency, consistency and institutional oversight that models can provide. But they also know clients do not have standardized financial lives. Clients have legacy holdings, embedded gains, concentrated positions, tax sensitivities, income needs, personal preferences and different expectations around communication.

The hurdle question reinforced this. 42% of advisors cited lack of customization as a key obstacle to broader model adoption. Another 37% pointed to the challenge of communicating portfolio changes and decisions to clients. 22% cited concern about losing a differentiated value proposition.³

This is where I think the “Financial M.D.” concept becomes useful — and it is a framework I have written about before.

A good doctor does not personally invent every test, build every tool or manufacture every medicine. Patients do not expect that. What they expect is a trusted professional who understands their situation, leverages the right specialists and resources, makes a thoughtful diagnosis and communicates the plan clearly.

Financial advisors are increasingly playing a similar role.

In WisdomTree’s model portfolio research, 9 out of 10 investors welcome their advisor to use third-party model portfolios.⁴ The same research found that 7 out of 10 investors believed model portfolio use would be an upgrade, and 7 out of 10 believed it could improve portfolio performance.

That is powerful because many advisors still worry that using third-party models may weaken their value proposition. The data suggests clients often see it differently. They view model portfolios as a form of leveraged expertise: their advisor combining personal knowledge of the client with the investment research, resources and portfolio management capabilities of an institutional asset manager.

And that is the essence of becoming the client’s Financial M.D. The advisor remains the trusted relationship, the diagnostician and the communicator — while leveraging specialists, technology and institutional resources to help support a more personalized portfolio experience.

But the RIA Channel polling shows that leveraged expertise now needs an added layer: personalization at scale.

That is where SMAs, direct indexing and tax-aware implementation come into the conversation. These tools can help advisors extend the model portfolio value proposition beyond “outsourced asset allocation” toward more customized, tax-sensitive client outcomes.

The challenge is that personalization can create complexity.

A model portfolio may look scalable on paper. In practice, taxable accounts, cash flows, restrictions, transitions and rebalancing can create meaningful operational drag. Advisors do not just need a model; they need an implementation engine that helps make the model work across real client accounts.

That is why the Quorus discussion was so relevant to the webcast and can serve as the “missing link.”

Quorus is designed to support custom, tax-aware portfolio management across model portfolios, SMAs and unified managed accounts. Its capabilities include daily, lot-level management, tax-loss harvesting, tax-aware transitions, trading, reconciliation and after-tax reporting.

The investor demand is there as well. The Quorus materials cited Cerulli research showing that 78% of affluent investors believe it is important that their accounts are customized to their specific situation, while 69% believe it is important that their provider helps reduce their tax bill.⁵

That lines up almost perfectly with what advisors told us in the polling.

Advisors want the scale of models. Clients want personalization and tax awareness. The missing link is the operational infrastructure to deliver both without forcing advisors to become full-time traders, tax-lot analysts and portfolio operations specialists.

To me, this is the future of model adoption: models plus personalization, institutional portfolio management plus advisor differentiation, and technology that helps advisors spend more time acting as their clients’ Financial M.D.

The advisors who get this right may be the ones who combine the best of both worlds: scalable portfolio implementation and a client experience that still feels personal, tax-aware and deeply connected to each household’s goals.
