What’s actually slowing this PC down?

Choose a Nasdaq-100 ETF by comparing its current expense ratio with the costs you actually incur to buy, hold, and sell it—not by picking the fund with the smallest advertised fee. A low fee can be outweighed by trading costs, while tracking and index implementation affect how closely your investment follows its benchmark.
What a Nasdaq-100 ETF gives you
The Nasdaq-100 is an index, not a fund you can buy directly. An ETF is one way to invest in securities intended to provide exposure to that index; Nasdaq lists QQQ and QQQM among the available ways to invest in it. The SEC-filed QQQ/QQQM supplement describes the index as designed to include securities of 100 of the largest domestic and international non-financial companies listed on U.S. exchanges. That is an index-design description, not a guarantee that a fund holds exactly 100 securities at every moment. Nasdaq: Nasdaq-100 · SEC-filed QQQ/QQQM supplement, April 30, 2026
These funds are not interchangeable with a broad-market ETF: they track a particular group of large non-financial companies listed on U.S. exchanges. Consider whether that concentration fits your portfolio before choosing among funds that follow the index.
Compare the costs that affect your result
Start with the expense ratio, but treat it as one part of ownership cost. Invesco reported a 0.15% total expense ratio for QQQM in its Q1 2026 product information. This is a dated figure, not a promise that the rate will remain unchanged; check the fund’s latest prospectus for the current expense ratio and any waiver. Invesco QQQM product information

Do not compare a fund’s gross expense ratio with another fund’s net rate without accounting for waivers. For example, the iShares Nasdaq 100 ETF summary prospectus dated July 8, 2026, reports a 0.02% fee waiver and/or expense reimbursement, but the available excerpt does not show the complete net fee or the waiver’s end date. That figure alone is not the fund’s expense ratio and is not enough to rank it against QQQM. Read the prospectus for the gross and net rates, waiver terms, and expiration date before drawing a comparison. iShares Nasdaq 100 ETF summary prospectus, July 8, 2026
Invesco also identifies other ownership costs: bid-ask spreads, trading commissions, and premiums or discounts to net asset value. A spread is the gap between the price buyers are bidding and sellers are asking; it is a trading cost, not part of the expense ratio. A premium or discount means the ETF’s market price is above or below its net asset value. Check these costs for the market and trading conditions in which you expect to transact, rather than assuming they are identical across funds or constant over time. Invesco QQQM product information
Check liquidity against how you trade
Liquidity matters most when you buy or sell: it can affect how readily an order is filled and the price you receive. A long-term investor making occasional purchases may weigh a small difference in trading costs differently from someone who trades frequently or places larger orders. Compare bid and ask prices near the time you plan to trade, and account for any commission or other charge imposed by your brokerage.
Available sources do not establish comparable current spreads, liquidity, or a complete peer set of Nasdaq-100 ETFs. Do not infer that one candidate is cheaper to trade simply from its name, share price, or expense ratio. Use current market data and your own account’s fee schedule.

An ETF’s objective is to follow its benchmark, but its return can diverge from the index’s return. Invesco identifies expenses, transaction costs, unavailable securities, and extraordinary circumstances as reasons for possible divergence. Compare fund returns with the correct index over the same periods, using the same dates and return basis; a single short period may not describe long-run tracking. Invesco QQQM product information
Also check the benchmark and how the fund implements it. Nasdaq says it implemented targeted Nasdaq-100 methodology updates on May 1, 2026, following public consultation. The QQQ/QQQM supplement states that the changes take effect on that date. If you compare historical returns across the change, remember that index methodology is part of what the fund tracks; the update alone does not establish what future performance will be.

Use share price only for purchase sizing
A fund’s share price can affect how much you can invest in a single share, particularly if your account does not offer fractional-share purchases. It does not show whether the fund is cheaper or better value: compare expense ratios, trading costs, and tracking instead. Check whether your brokerage supports fractional ETF shares and whether any limits or fees apply.

- Confirm the benchmark. Verify that each fund seeks to track the Nasdaq-100 and review any stated differences in objective or implementation.
- Read the current prospectus. Record each fund’s gross and net expense ratios, and note whether a waiver applies and when it expires.
- Estimate trading costs. Check the bid-ask spread under relevant trading conditions, brokerage commissions or fees, and whether the market price is at a premium or discount to net asset value.
- Match liquidity to your use. Consider your order size and trading frequency; use current market data rather than assuming liquidity from a fund’s expense ratio.
- Compare tracking over like periods. Review fund and index returns for matching dates and the same return basis, and account for benchmark methodology changes.
- Check purchase practicality. If a single share exceeds your intended contribution, find out whether fractional shares are available; do not treat share price as a measure of value.
No complete current peer fee table or comparable market-spread data is established here, so these facts do not identify a universally cheapest Nasdaq-100 ETF. Recheck filings and market data before investing. Your time horizon, tax circumstances, trading behavior, account costs, and existing portfolio concentration can all affect which costs matter most. Past performance does not guarantee future results; this guide is general information, not individualized financial advice.
