What is the best broker for ETF investing in 2026?

Fidelity is our #1 pick for ETF investing in 2026. It offers $0 commissions on 2,000+ ETFs, fractional ETF shares from $1, ZERO expense ratio index funds (FZROX at 0.00%), and the best ETF screener available to retail investors. For global ETF access, Interactive Brokers with 13,000+ ETFs is unmatched.

What expense ratio should I look for in an ETF?

For broad market index ETFs, target under 0.10%. Fidelity's FZROX is 0.00%. Vanguard's VTI, Schwab's SCHB, and iShares's IVV are all 0.03%. Sector ETFs typically charge 0.20%–0.75%, and thematic ETFs can reach 0.50%–1.00%. Every 0.10% of expense ratio costs approximately $100/year per $100,000 invested.

Can I invest in ETFs with no money?

Yes. Fidelity and SoFi Invest both support fractional ETF shares starting from $1. This means you can buy exactly $50 of VOO or $10 of VTI regardless of the current share price — making diversification accessible at any account size.

What is the three-fund portfolio?

The three-fund portfolio is a simple, proven passive investing strategy: (1) a total US stock market ETF like VTI, (2) a total international stock ETF like VXUS, and (3) a total bond market ETF like BND. Adjust the ratio based on your age and risk tolerance. At Fidelity, FZROX + FZILX + FXNAX achieves the same result at literally 0.00% combined expense ratio.

Should I hold ETFs in a taxable account or an IRA?

Ideally both, with tax-aware placement. Hold tax-inefficient ETFs (bond funds, REIT ETFs, high-dividend ETFs like SCHD) inside a Roth IRA to shield distributions from tax. Hold tax-efficient broad equity ETFs (VTI, VXUS) in taxable accounts where long-term capital gains rates are favorable. This "asset location" strategy can add 0.5%–1.0% to annual after-tax returns.

Is a robo-advisor the same as ETF investing?

Most robo-advisors invest in ETFs — they build a diversified portfolio of low-cost ETFs and rebalance automatically. Fidelity Go and Schwab Intelligent Portfolios both use ETF-based portfolios. The difference is control: self-directed ETF investing lets you choose specific funds and tilts; robo-advisors choose for you. For most investors, a robo-advisor is a fine starting point.

Why Your ETF Broker Actually Matters

Since nearly every broker went to $0 ETF commissions in 2019, most investors assume all ETF platforms are equal. They're not. The real differentiators are expense ratio access, ETF screener quality, fractional share support, and selection depth — and the differences add up to thousands of dollars over a 30-year horizon.

Expense Ratio Access

The broker you choose determines what funds you can access. Only Fidelity carries 0.00% ER funds. At every other broker, the cheapest US equity ETF is 0.03%. On $500K, that's $150/year difference — $4,500 over 30 years before compounding.

ETF Screener Quality

A quality screener lets you find low-cost ETFs by asset class, factor, yield, or region in seconds. Schwab and Fidelity lead here. At a broker with poor screening, you might miss cheaper alternatives.

Fractional Share Support

Fractional shares let you invest exact dollar amounts regardless of ETF share price. This matters for small accounts and dollar-cost averaging. Not all brokers support it — Webull, for example, does not.

ETF Selection Depth

For international, thematic, or factor ETFs, some brokers carry 500 while IBKR carries 13,000+. If you need niche exposure — Vietnam ETF, MSCI World Momentum, European dividend — selection depth matters enormously.
