ONEQ vs QQQM: Which Is the Better Pick in 2026?

Overview

ONEQ and QQQM are both Nasdaq-tracking equity ETFs, but they differ fundamentally in scope and construction. ONEQ tracks the entire Nasdaq Composite Index—roughly 3,000 stocks spanning large, mid, and small cap—while QQQM tracks the more concentrated Nasdaq-100 Index, which holds just the 100 largest non-financial Nasdaq stocks. The choice between them hinges on whether you want broad market exposure or focused mega-cap and tech-heavy concentration.

How they differ

The biggest difference is breadth: ONEQ captures the full Nasdaq universe; QQQM holds the 100 largest names only. This makes QQQM far more concentrated in megacap technology and growth stocks, while ONEQ includes meaningful exposure to smaller companies and diversified sectors. Second, QQQM is vastly larger by assets under management—$68.8 billion versus ONEQ's $8.6 billion—which translates to tighter bid-ask spreads and better liquidity for QQQM. Third, QQQM's expense ratio is 0.15% versus ONEQ's 0.21%, a modest but real advantage over decades of holding. Both funds distribute yields under 0.55% and carry similar betas (QQQM at 1.11, ONEQ at 1.18), meaning both track their indexes closely but with meaningful equity market leverage.

Who each is best for

ONEQ: Investors seeking broad exposure to all Nasdaq-listed stocks and willing to tolerate higher small-cap and mid-cap volatility; best suited for long-term buy-and-hold accounts where the slightly higher expense ratio matters less than diversification.

QQQM: Core-equity portfolio builders who want concentrated mega-cap and technology exposure with lower costs; ideal for accounts already holding broad-market exposure (like VOO or VTI) and seeking high-growth tilt without paying QQQ's higher 0.20% fee.

Key risks to know

• Concentration risk in QQQM: The Nasdaq-100's largest 10 holdings represent roughly 45% of the index. A downturn in megacap tech translates directly into significant portfolio losses.

• Beta above 1.0 in both: Both funds amplify broad market moves. In a 10% market decline, expect 11–12% losses. Neither is defensive.

• Small-cap drag in ONEQ: Smaller Nasdaq stocks in ONEQ carry higher bankruptcy and liquidity risk than the mega-cap anchor in QQQM. In credit-stress environments, ONEQ's smaller holdings may underperform.

• Valuation sensitivity: Both funds are heavily weighted to unprofitable and high-growth names. Rising rates or deteriorating earnings growth pose material headwinds.

Bottom line

If you want broad, diversified Nasdaq exposure and already hold a U.S. total-market fund, ONEQ adds meaningful small and mid-cap exposure. If you're building a core portfolio and want pure mega-cap growth with the lowest cost and tightest spreads, QQQM is the cleaner choice. Past performance in the Nasdaq's 2020–2021 run doesn't predict how these funds will behave in a higher-rate or slower-growth environment.
