If you needed proof that ETFs have gone from investing novelty to absolute necessity, Charles Schwab just delivered it. The firm's latest "ETFs & Beyond" study surveyed 2,000 experienced investors split evenly between ETF users and non-users, and the results suggest we're watching a fundamental shift in how people build portfolios.

Here's the headline number: 93% of ETF investors now say this investment vehicle is a necessary part of their portfolio. Not useful. Not convenient. Necessary. And 75% are extremely likely to buy more over the next two years. That's not adoption anymore—that's devotion.

The Newer Crowd Is Going Harder

What makes this particularly interesting is the intensity among recent converts. Two-thirds of current ETF investors only started buying after 2020, yet they've embraced the format with the same fervor as veterans who've been holding for years. There's no gradual warming period here.

The confidence level keeps climbing. In 2025, 62% of all ETF investors say they'd consider putting their entire portfolio in ETFs, a sharp jump from 2020 levels. That conviction runs strongest among newer investors, which tells you where the industry is headed.

The allocation numbers back this up. Investors expect ETFs to comprise 34% of their portfolios within five years, up from 27% today. That upward trajectory holds remarkably consistent across all generations, suggesting this isn't just a generational quirk but a broader market evolution.

Portfolio construction is evolving too. More than half of investors now blend core ETF holdings with tactical or niche exposures. Dividend ETFs remain the dominant specialty choice, but single-stock ETFs, thematic funds, long/short strategies, and spot crypto ETFs are all gaining traction. ETFs are also becoming the gateway to asset classes once considered difficult to access—commodities, private equity, even private credit. The line between simple indexing and sophisticated strategy deployment keeps getting blurrier.

Bonds Are Back in Fashion

One fresh development in 2025 is the comeback of fixed-income ETFs. After spending the rate-hiking cycle repositioning their portfolios, 40% of ETF investors now expect to increase their bond ETF allocations. That puts funds like Vanguard Intermediate-Term Bond ETF (BIV) and Fidelity Total Bond ETF (FBND) squarely in the spotlight. Investors cite both diversification needs and the belief that higher-for-longer rates will continue reshaping return opportunities.

Cost remains king across all investor groups, though Millennials are more likely than Gen X or Boomers to rank it as their single most important consideration. That said, investors are willing to pay up for active ETFs when they deliver downside protection, access to alternative strategies, or exposure to managers they trust. Low fees matter, but they're not the only thing that matters.

Millennials Lead, Boomers Hold Steady

The demographic breakdown is where things get really interesting. Millennials are the ETF power users of 2025. They're allocating the highest portfolio share—30% today, projected to hit 36% within five years—and overwhelmingly plan to increase allocations this year. They're also the most interested in cryptocurrencies, tangible assets, alternatives, and specialty products.

Millennials tend to self-identify as tactical investors who believe they have the skills to outperform the market. That's a sharp contrast with Boomers, who still favor buy-and-hold strategies and stick to more traditional asset-class exposures. Gen X lands in the middle, mixing tactical moves with the conservatism that comes with later-career financial planning.

Across the board, investors want more control, customization, and tax optimization. But Millennials and Gen X are significantly more eager than Boomers to explore direct indexing. Nearly one-third of ETF investors say they're very likely to adopt direct indexing within the next 12 months. Portfolio personalization is emerging as the next major frontier, and it's not a distant future thing—it's happening now.
