How the QQQ ETF works (Nasdaq-100)

By AP Dult · AI-assisted · October 29, 2026 · Issuer facts checked Oct 29, 2026

General information and education only. Nothing here is a recommendation to buy, sell, or hold QQQ or any other security.

QQQ is the ticker for the Invesco QQQ Trust, a well-known U.S. exchange-traded fund (ETF). Beginners meet it constantly in pre-market chatter because it is a liquid way to trade a basket of large Nasdaq-listed companies in one line. Here is what it is — and what it is not — using the issuer and U.S. investor-education sources.

What an ETF is (30 seconds)

The SEC’s Investor.gov glossary: an ETF is an exchange-traded investment product that must register with the SEC (typically as an open-end investment company, sometimes as a unit investment trust). Like a mutual fund, it pools investor money into a portfolio. Unlike a typical mutual fund, investors buy and sell ETF shares on national securities exchanges at market prices during the trading day.

What QQQ specifically tracks

Invesco’s About QQQ page states that Invesco QQQ ETF tracks the Nasdaq-100 Index, giving access to the performance of the 100 largest non-financial companies listed on the Nasdaq. The fund and the index are rebalanced quarterly and reconstituted annually.

Invesco also notes QQQ’s inception date of March 10, 1999, and states that Invesco QQQ’s total expense ratio is 0.18% (as published on the issuer marketing page we checked Oct 29, 2026 — verify the live figure before you use it).

Holdings change. Never treat a screenshot of top names as permanent. Use Invesco’s holdings page for the current list.

How trading QQQ differs from owning “the Nasdaq”

• Index ≠ fund. You cannot invest directly in the Nasdaq-100 index. QQQ is a fund that seeks to track that index before fees.
• Market price vs NAV. ETF shares trade all day; the net asset value is a separate calculation. Prices can trade at a premium or discount, especially in fast markets.
• Concentration. A 100-name, non-financial Nasdaq basket is not a total-market portfolio. Sector weights can be heavy in technology and related growth industries — check current allocations on the issuer site.
• Costs. Beyond the expense ratio, spreads and commissions (if any) are part of total cost of ownership, as Invesco itself notes in its ETF education copy.

Where QQQ shows up in a morning brief

Futures and pre-market quotes on Nasdaq-100 products are a common “risk-on / risk-off” tell before the cash open. When AP's Morning Brief cites QQQ or Nasdaq-100 levels, the edition links the quote source and timestamp. This evergreen page keeps no live price so the explanation does not rot.

Regular U.S. equity session hours are 9:30 a.m. to 4:00 p.m. Eastern Time; Nasdaq also describes extended sessions around that window. Extended-hours trading has extra risks (liquidity, volatility, wider spreads) — see the SEC’s Investor.gov bulletin linked below.
