The ETF Revolution Is Entering Its Next Phase

For years, the basic appeal of ETFs was very straightforward. Investors would get an effective, low-cost, often tax efficient way to track broad market indexes. Instead of buying dozens or hundreds of individual securities, an investor could purchase a single ETF and gain diversified exposure to an entire market.

Simple, straightforward.

While this basic value proposition remains intact, the ETF market today looks very different from the one that first popularized passive investing.

U.S.-listed ETFs are expected to attract more than $2 trillion in investor inflows in 2026, which would represent roughly a 40% increase from 2025. Total assets in U.S. ETFs have already climbed to approximately $16.1 trillion, while more than 1,100 new ETFs launched last year alone. At the current pace, the number of U.S.-listed ETFs is expected to surpass 6,000—more than the number of individual stocks listed on U.S. exchanges.¹

On the surface, this explosion of choice looks unequivocally positive for investors. And in many ways, it is—ETFs have made markets more accessible, lowered costs, and given investors tools that would have been difficult or expensive to access just a generation ago.

But more choice does not necessarily lead to better investment decisions, in our view.

In fact, the rapid expansion of the ETF universe—particularly among actively managed and increasingly specialized strategies—may be creating a new challenge for investors. When there are more than 6,000 ETFs to choose from, the difficult part is no longer gaining access to an investment idea. It’s determining which ideas actually deserve a place in your portfolio.

Consider the pace of new product creation. More than 1,100 ETFs launched in the U.S. last year alone, with investors now able to find funds targeting an extraordinary range of sectors, industries, themes, factors, asset classes, and investment strategies. But the existence of an ETF does not necessarily mean the strategy it tracks belongs in a diversified portfolio.

To put it another way, rapid growth in the ETF market is good for investor choice, but it also puts more responsibility on investors to look beneath the ETF wrapper.

Investors should know what an ETF actually holds, what its strategy is designed to accomplish, how much it costs, and what risks come with the exposure. With an actively managed ETF, there is another layer to consider: what decisions is the manager making, and what evidence is there that the investment process is disciplined and repeatable?

There is also a broader portfolio question that can easily get lost amid all this choice, which is that owning more ETFs does not necessarily mean being more diversified. An investor might own a broad-market ETF alongside several technology, artificial intelligence, semiconductor, growth, and thematic ETFs and assume that each fund adds another layer of diversification. Look under the hood, however, and those funds may own many of the same securities or respond to many of the same underlying economic forces. An investor may have more concentration risk in their portfolio than they appreciate.

The same issue can arise across asset classes. Adding another fund to a portfolio is only useful if investors understand what exposure it adds, how that exposure behaves relative to existing holdings, and what role it is supposed to play.

That shift gets closer to what we believe is the real opportunity created by the ETF boom. ETFs can provide efficient access to U.S. and international stocks, fixed income, real estate, commodities, individual sectors, and a wide range of other exposures. But access is only the starting point. Investors still need to decide how those pieces fit together, how much capital to allocate to each, and when changing market conditions warrant an adjustment.

Bottom Line for Investors

More than $2 trillion could flow into ETFs this year, and thousands of funds are now competing for investor dollars. That growth has created more investment tools and more flexibility than investors have ever had before. It has also made selectivity more important.

At Zacks Advantage, we believe the goal is not to own more ETFs or to chase whichever new strategy is attracting attention. ETFs are tools within an actively managed portfolio. Each exposure should have a defined purpose, complement the other investments in the portfolio, and support an allocation consistent with an investor’s risk tolerance and long-term objectives.

Passive investing has made the stock market more accessible than ever, virtually anyone can buy an ETF and own the S&P 500.

But there’s a tradeoff: a purely passive strategy can’t outperform the market, because it is the market. Zacks Advantage takes a different approach with an actively managed robo-advisor that:

• Invests exclusively in ETFs
• Uses technology to build the right mix of equity and bond ETFs for your goals and risk tolerance
• Keeps fees and expenses low
