QQQ remains one of the most heavily traded ETFs in the world, with extremely tight bid-ask spreads and massive daily volume. This makes it the better choice for active traders and institutions. But for buy-and-hold investors contributing monthly to a retirement account, QQQM saves 5 basis points per year with no practical downside.

Nasdaq-100 Concentration Risk
The Nasdaq-100 is not the total market. It holds 100 stocks, heavily weighted toward mega-cap technology and growth companies. The top 10 holdings typically represent around 50% of the entire index weight.
This concentration has driven strong returns over the past decade as tech stocks have outperformed. But it also means higher volatility and sector-specific risk. If you want broad diversification, pair Nasdaq-100 exposure with a total market fund like VTI/VTSAX.
