Top ETFs for American Long-Term Investors in 2026

Top ETFs for long-term investors in 2026 tend to share the same handful of traits: low fees, broad diversification, and a track record that doesn't depend on chasing whatever sector happens to be hot. That's easy to say and harder to act on, especially when there are thousands of exchange-traded funds competing for your attention, from plain S&P 500 trackers to niche thematic funds built around a single idea that may or may not still matter in five years.

This guide breaks down the categories that actually matter for a buy-and-hold investor: core U.S. index funds, international exposure, bonds, dividend growth, and real estate. Instead of chasing last quarter's winner, we're focused on funds that have historically justified a spot in a portfolio meant to be held for a decade or more.

A quick note before we dive in: this article is for informational purposes only and isn't personalized financial advice. Expense ratios, holdings, and performance figures change over time, so always check a fund's current prospectus before investing, and consider talking to a licensed financial advisor about what fits your specific situation.

With that out of the way, let's look at the best ETFs to buy and hold in 2026, organized by category so you can build a portfolio that matches your actual goals instead of just picking whatever's trending.

What Makes an ETF Good for Long-Term Investing

Before naming specific funds, it helps to know what separates a solid long-term holding from a fund that looks exciting but doesn't belong in a buy-and-hold portfolio. The best long-term ETFs generally share these traits:

• Low expense ratio. Even a difference of 0.20% a year compounds significantly over 20 or 30 years. Broad index ETFs routinely charge under 0.10%.
• Broad diversification. Funds tracking hundreds of companies reduce the risk that a single stock's collapse tanks your portfolio.
• Sufficient trading volume and assets under management. Larger funds tend to have tighter bid-ask spreads and lower odds of being shut down.
• A track record through multiple market cycles. A fund that only exists because of a recent trend hasn't been tested by a real downturn yet.
• Tax efficiency. ETFs are generally more tax-efficient than mutual funds because of how shares are created and redeemed, which matters if you're investing in a taxable brokerage account.

Keep these criteria in mind as a filter any time you're evaluating a fund that isn't on this list.

Core U.S. Index ETFs

For most long-term investors, core index ETFs tracking the S&P 500 or the total U.S. stock market should form the foundation of a portfolio. These funds own hundreds of the largest American companies, and history shows that very few actively managed funds beat them over long stretches of time.

S&P 500 Index ETFs

The S&P 500 ETF category includes some of the largest and most heavily traded funds in the world:

• Vanguard S&P 500 ETF (VOO): One of the cheapest ways to own the S&P 500, with an expense ratio around 0.03%.
• iShares Core S&P 500 ETF (IVV): Nearly identical to VOO in cost and holdings, from a different fund provider.
• SPDR S&P 500 ETF Trust (SPY): The oldest and most heavily traded S&P 500 ETF, though it carries a slightly higher expense ratio than VOO or IVV.

All three funds hold essentially the same 500 companies and have delivered comparable returns over time. The main difference comes down to cost and which brokerage ecosystem you're already using.

Total Market ETFs

If you want exposure beyond just the 500 largest companies, a total stock market ETF like the Vanguard Total Stock Market ETF (VTI) adds mid-cap and small-cap companies to the mix. This gives you a slightly more complete slice of the U.S. economy without meaningfully increasing your fees, since VTI's expense ratio is also close to 0.03%.

Growth and Tech-Heavy ETFs

For investors comfortable with more volatility in exchange for historically higher growth, Nasdaq-100 ETFs like the Invesco QQQ Trust (QQQ) or its lower-cost sibling QQQM offer heavy exposure to large technology companies. These funds have posted strong returns over the past decade, but they're also more concentrated in a handful of mega-cap tech names, so they work best as a complement to a broader index fund rather than a full replacement for one.

International ETFs

Relying entirely on U.S. stocks means missing out on growth happening everywhere else, and it concentrates your risk in a single economy. International ETFs solve this by giving you exposure to developed and emerging markets without the hassle of buying individual foreign stocks directly.

Common approaches include:

1. Developed markets funds, which focus on established economies like Japan, the U.K., and Germany.
2. Emerging markets funds, which include countries like India, Brazil, and China, and tend to carry more volatility along with higher long-term growth potential.
3. Total international funds, which blend both developed and emerging markets into a single fund for simplicity.

A reasonable long-term allocation for many investors is somewhere between 10% and 30% international, though the right number depends on your personal risk tolerance and time horizon.

Dividend and Income ETFs

For investors who want steady cash flow alongside growth, dividend ETFs focus on companies with a history of paying, and often increasing, their dividends year after year. These funds tend to hold more established, financially stable companies, which can make them somewhat less volatile than growth-focused funds during market downturns.

Two common styles worth understanding:

• Dividend growth funds prioritize companies with a long streak of increasing their payouts, even if the current yield is modest. These tend to hold higher-quality, more stable businesses.
• High-yield dividend funds prioritize current income over growth, which can mean a higher yield today but sometimes less capital appreciation over time.

Dividend ETFs work well inside a diversified portfolio, but they shouldn't be your only equity holding, since they tend to underweight fast-growing companies that don't pay dividends at all.

Bond ETFs for Stability

No long-term portfolio is complete without some allocation to bond ETFs, which help cushion the impact of stock market downturns and provide more predictable income. The right mix depends heavily on your time horizon and how much volatility you can tolerate.

• Short-term bond ETFs are less sensitive to interest rate changes and work well for money you might need in the next few years.
• Intermediate-term bond ETFs balance yield and interest rate risk, making them a common core holding for a 10-plus year time horizon.
• Total bond market ETFs blend government and corporate bonds across maturities into one fund, simplifying the process of getting broad fixed-income exposure.

As you get closer to needing the money, whether for retirement or another major goal, gradually shifting more of your portfolio toward bonds is a standard way to reduce risk without abandoning the market entirely.

Real Estate ETFs (REITs)

Real estate ETFs, often built around Real Estate Investment Trusts (REITs), let you invest in commercial real estate, like apartment buildings, warehouses, and offices, without buying physical property yourself. REITs are legally required to distribute most of their taxable income as dividends, which makes these funds attractive for income-focused investors.

A fund like the Vanguard Real Estate ETF (VNQ) holds well over 100 individual REITs, spreading risk across many property types and regions rather than betting on a single building or market. Real estate ETFs can add diversification to a portfolio since real estate doesn't always move in the same direction as the broader stock market, though they come with their own risks tied to interest rates and local property markets.

How to Build a Long-Term ETF Portfolio

Putting these categories together into an actual portfolio doesn't need to be complicated. A simple, well-diversified approach for a long-term investor might look like:

1. 60-70% in core U.S. index funds (S&P 500 or total market ETFs) as the foundation.
2. 10-20% in international ETFs for global diversification.
3. 10-20% in bond ETFs, with the percentage increasing as you get closer to your goal.
4. Optional 5-10% allocation to dividend or real estate ETFs if income or additional diversification is a priority.

This is a general framework, not a prescription. Your actual allocation should reflect your age, risk tolerance, and specific financial goals. The U.S. Securities and Exchange Commission publishes plain-language investor guidance at Investor.gov that's worth reading if you're building a portfolio for the first time.

Common Mistakes Long-Term ETF Investors Make

• Chasing performance. Buying whatever ETF had the best return last year often means buying in near a peak.
• Overlapping funds without realizing it. Owning both an S&P 500 fund and a total market fund means you're paying two expense ratios for largely the same exposure.
• Ignoring expense ratios. A 0.5% fee might look small, but it can cost tens of thousands of dollars over several decades compared to a fund charging 0.03%.
• Panic selling during downturns. Long-term ETF investing works because you stay invested through the dips, not despite them.
• Not rebalancing. Over time, winning asset classes grow to make up a larger share of your portfolio than intended, quietly increasing your risk.

Frequently Asked Questions

Are ETFs better than mutual funds for long-term investing? ETFs are generally more tax-efficient and often cheaper than comparable mutual funds, which makes them a popular choice for taxable brokerage accounts. Some investors still prefer mutual funds for automatic investing features inside retirement accounts.

How many ETFs do I actually need? A well-diversified portfolio can realistically be built with three to five ETFs covering U.S. stocks, international stocks, and bonds. More funds don't necessarily mean more diversification if their holdings overlap.

Should I invest in ETFs inside a retirement account or a taxable account? Both work, but tax-advantaged accounts like a 401(k) or IRA are generally the better home for less tax-efficient holdings like bond funds or high-dividend ETFs, while broad index ETFs can work well in either type of account.

What's a reasonable expense ratio to look for? Broad index ETFs commonly charge 0.03% to 0.10%. Anything meaningfully above that should have a clear reason, like active management or a specialized strategy, to justify the extra cost.

Conclusion

Building a strong ETF portfolio for the long haul doesn't require predicting which sector will outperform next year. It comes down to combining low-cost, broadly diversified funds across U.S. stocks, international markets, bonds, and, if it fits your goals, dividend or real estate exposure, then leaving the portfolio alone long enough for compounding to do its work. The specific funds you choose matter less than sticking to the core principles covered here: keep costs low, diversify broadly, and resist the urge to chase whatever's performed best recently. Do that consistently, and the rest of the strategy tends to take care of itself.
