Overview
QNDX and QQQ are both ETFs tracking the identical Nasdaq-100 Index, which includes 100 of the largest non-financial companies listed on the Nasdaq exchange. The key distinction is scale: QQQ is one of the oldest and largest equity ETFs in the world with $479B in AUM, while QNDX is a much smaller State Street alternative with $24.9M in AUM launched in 2026. Both charge minimal fees but QQQ carries a slightly higher expense ratio despite vastly larger assets.
How they differ
Both funds track the same benchmark, so their holdings and performance are essentially identical before fees. QQQ's expense ratio of 0.18% is 8 basis points higher than QNDX's 0.10%, a gap that compounds to a meaningful return drag over years but widens or narrows depending on which fund benefits from share-creation economics as assets move. QQQ's $479B asset base gives it far deeper liquidity and tighter bid-ask spreads, while QNDX's $24.9M in AUM is small enough that trading costs could meaningfully exceed its fee advantage in practice. QQQ has a 27-year track record and distributes 0.44% annually; QNDX's distribution rate is not specified, though both pay quarterly.
Who each is best for
QNDX: Fits investors evaluating index trackers on expense ratio alone and comfortable with potentially wider trading spreads or longer wait times for fills given the fund's modest asset base.
QQQ: Designed for core Nasdaq-100 exposure seekers who value deep liquidity, tight spreads, and 27 years of operating history, willing to accept 8 basis points annually in exchange for institutional-grade trading mechanics.
Key risks to know
- Concentration in mega-cap tech. The Nasdaq-100 is heavily weighted toward a handful of semiconductor, AI, and software companies. A downturn in that cluster poses outsized downside risk to both funds.
- Expense ratio tradeoff with liquidity. QNDX's lower fee advantage evaporates if trading friction—bid-ask spread, market-impact costs, or execution delays—exceeds 8 basis points per trade; QQQ's larger asset base subsidizes tighter spreads that can offset its higher stated fee for active traders.
- Growth-factor cyclicality. Both funds carry a beta of 1.24 (QQQ; QNDX's beta is not reported), meaning they amplify broad market downturns and outperform in growth rallies. Valuations in large-cap growth are sensitive to interest-rate expectations, creating sustained drawdown risk in rising-rate environments.
- Asset base divergence. QNDX's small AUM means it could face closures, forced mergers, or slow adoption if State Street deprioritizes the fund, leaving holders to migrate to another vehicle.
Bottom line
QQQ's liquidity advantage and operating history come at a modest cost; QNDX's fee savings are real but only meaningful if you trade rarely or in tiny size. If you prioritize the lowest stated fee and have sufficient patience with tighter spreads, QNDX appeals; if you need institutional-grade execution and institutional-grade comfort with scale, QQQ's additional 8 basis points is unlikely to be the limiting factor.
