Why “Customized” Portfolios Still Look the Same

Joseph S. RizzelloAdvisor Perspectives welcomes guest contributions. The views presented here do not necessarily represent those of Advisor Perspectives.

Ask a room full of advisors whether their client portfolios are personalized, and nearly all of them will say yes.

The contents of those portfolios might tell a different story. Assets in third-party model portfolios reached more than $645 billion by March 2025, according to Morningstar, a 62% increase in less than two years.

I want to be clear that broad-market indexing has genuine merit. It delivers efficient exposure to markets and has driven costs down for millions of investors. We use them as an allocation tool inside tactical models.

The Evolution From Tailored Solution to Off-the-Shelf Product

I’ve watched that packaging happen from the inside. Early in my career, I led a team at the Philadelphia Stock Exchange that did product engineering, creating things like currency options so multinational companies could actually manage exchange-rate exposure instead of treating it as an act of God.

One of those projects became the semiconductor index. Today it’s accessible through an ETF, the same as gold, silver, and half a dozen other market sectors. A tool built to solve a specific problem eventually getting wrapped into something anyone can buy off the shelf is not a bad thing on its own.

The issue is the growing trend of sorting clients into one of a handful of pre-built models and calling the result personalized, regardless of whether the products inside that model are active or passive. Wall Street is one of the most effective marketing machines ever built, and it has done its job well. Main Street has been sold on the idea that a standardized allocation and a personalized one are the same thing.

When portfolios become standardized, investor experience becomes standardized right along with them, even though almost nothing else about those investors is standard. Their goals, tax exposure, risk tolerances, and individual spending needs are too individualized to be captured by many models that purport to be customized.
