Fidelity Nasdaq Composite Index ETF (ONEQ)

The Fidelity Nasdaq Composite Index ETF (ONEQ) mirrors the Nasdaq Composite, the complete universe of stocks trading on the Nasdaq exchange. Unlike Nasdaq-100 funds that capture only the largest 100 companies, ONEQ holds roughly 3,000 names—a slice of the US equity market tilted toward technology and growth, but spanning small industrial firms, regional banks, and niche consumer companies.

ONEQ is the comprehensive choice for investors wanting Nasdaq exposure without concentration in mega-cap names.

The index. ONEQ tracks the Nasdaq Composite by holding nearly every stock that trades there. The composition skews technology—semiconductors, software, biotech cluster heavily—but includes mature industrial and consumer businesses. The megacaps dominate in dollar terms; a handful of giants account for a quarter or more of the index’s value. But thousands of smaller names, many with market capitalizations in the hundreds of millions to low billions, add genuine small-cap and mid-cap flavor. Fidelity, as sponsor, simply replicates the index mechanically, with no stock-picking or tactical tilts.

The alternative frame. Investors comparing ONEQ to the Nasdaq-100 (which holds only the largest 100 names) are choosing breadth over concentration. ONEQ captures the 101st-through-3,000th names on the Nasdaq, where growth may move faster and valuations sit wider apart than among the mega-cap elite. The trade-off is higher volatility and lower correlation with “big tech” moves.

Holdings skew. Technology and growth companies dominate by sector weight, a structural fact of what trades on the Nasdaq. In periods when big tech rallies, ONEQ tags along. In tech downturns, ONEQ falls harder than a market-cap-weighted US index would. The small and mid-cap slices add resilience when mega-cap growth stumbles, but they cannot fully hedge that sector concentration.

Costs and trading. The expense ratio is minimal, quoted in basis points. Trading happens on NYSE Arca with ample liquidity and tight spreads; retail and institutional investors alike enter and exit without material friction. ONEQ functions as a one-ticket way to own “the entire Nasdaq” without trading individual stocks or managing a portfolio.

Tracking fidelity. ONEQ’s returns should track the Nasdaq Composite precisely, minus only the stated expense ratio. Fidelity’s scale ensures that tracking error—slippage from the true index return—remains negligible. Any material deviation warrants investigation; persistent tracking error beyond a few basis points suggests operational or structural issues.

Index changes and turnover. The Nasdaq roster is not static. New companies list; others delist or merge. Fidelity rebalances quarterly to keep pace with index changes. Monitoring those changes—which sectors are entering, which exiting—offers a sense of where US innovation and capital are flowing.

The research path. Begin with Fidelity’s fact sheet: top holdings, sector breakdown, expense ratio confirmation. The prospectus details mechanical rebalancing rules and risks. Compare ONEQ’s historical returns to the S&P 500 or Russell 3000 to see how Nasdaq-concentrated exposure has behaved in different market conditions. Watch how ONEQ performs when interest rates shift (tech-heavy indexes tend to suffer when rates rise) and when sentiment toward growth stocks moves. That comparison clarifies whether the Nasdaq’s specific character fits your portfolio.
