QQQ vs. QQQM: Which Is Better for Long-Term Investors in 2026?

These two funds hold the same stocks in the same weights, from the same issuer, tracking the same index. The comparison is therefore narrow, and most of it comes down to three basis points and a trading ecosystem. Here is the answer first, and the reasoning after.

The short answer, by situation

What separates them

What changed in December 2025

For most of its life QQQ was a unit investment trust, a 1999-era structure that could not reinvest the dividends it received and could not lend its securities. Shareholders voted on December 19, 2025 to convert it to an open-end fund, it began trading in the new form on December 22, and the expense ratio fell from 0.20% to 0.18% the same day. Invesco said the change created no tax consequences for holders.³

This matters for reading anything written about the pair before 2026. The old comparison was partly structural: QQQM was cheaper and could do things QQQ could not. Now both are open-end funds and the gap is three basis points plus a trading ecosystem. Older articles that lead with the trust structure are describing a fund that no longer exists in that form.

Are they the same fund?

No, they are two funds tracking one index. Both prospectuses describe the Nasdaq-100 as having 102 constituents as of October 31, 2025.⁴ The index is named for 100 companies and holds slightly more securities than that because a few companies, such as Alphabet, have more than one share class in it.

Because they replicate the same index, their portfolios and sector weights are the same to the decimal. Invesco classifies both at 66.36% technology as of August 31, 2026, using the ICB scheme, which counts Alphabet and Meta as technology companies.¹ That figure looks higher than the tech weights usually quoted for this fund, and the reason is the scheme rather than the portfolio: under GICS those two names sit in communication services instead, which moves roughly nine percentage points out of the technology line. Both numbers describe the same holdings.

Where a real difference shows up

Against the index itself, over the periods Invesco publishes as of August 31, 2026, QQQM landed slightly closer every time. On one-year returns the index made 26.61%, QQQ 26.31% and QQQM 26.39%. Over five years the index made 14.46% a year, QQQ 14.21% and QQQM 14.30%.¹²

The direction is consistent and it favors the cheaper fund. Be careful about the size of it, though: the gap between the two funds runs about eight to twelve basis points a year in these tables, wider than the three basis points of fee, and a standardized return table is not a clean measurement of tracking difference. The honest summary is that both funds track the index closely, and the cheaper one tracked it a little closer.

Three basis points, in dollars

The fee gap is 0.03% a year. On $10,000 that is $3 a year. On $100,000 it is $30. Compounded, it is still small: one modeled path of $100,000 held for thirty years at an 8% gross return ends about $8,000 ahead in QQQM, which is roughly 0.8% more money. At a 7% gross return the same path gives about $6,100. Those figures move with the return you assume, which is the point: the fee difference is real, and it is not the thing that will decide how this position turns out.

A lower share price is not a discount

QQQM traded at a $296.12 NAV against QQQ’s $719.18 on September 4, 2026.¹² Some comparisons present that as a reason to prefer QQQM, and it is not one. Share price is the fund’s assets divided by however many shares it has chosen to issue. $10,000 buys the same slice of the same portfolio either way. The only practical effect is on a broker that cannot buy fractional shares, where a lower price wastes less cash at the edges, and most brokers now handle fractions.

Should you switch from QQQ to QQQM?

In a retirement account, go ahead. Selling inside an IRA or 401(k) creates no taxable event, so the switch costs a few minutes and nothing else.

In a taxable account with a gain, the arithmetic is lopsided in a way that surprises people. Three basis points on $250,000 is $75 a year. Selling a $250,000 position that is 60% gain, at a 23.8% federal rate including the net investment income tax, costs about $35,700 in tax. At $75 a year of saving, the naive payback is several centuries. Even a modest case does not rescue it: $100,000 with a 30% gain at 15% costs $4,500 in tax against $30 a year, which is still 150 years.

Those are illustrations at stated rates, and your own numbers will differ, so run them. The calculator below prices the tax at your brackets and state, applies any harvested losses you have, and tells you how long the fee saving takes to repay it. For a QQQ to QQQM switch it will usually answer “never,” which is the correct answer and the reason this section exists.

None of this argues for holding QQQ forever. It argues that the fee is the wrong reason to sell it. If you want out of the Nasdaq-100 for reasons about the index, that is a larger benefit and a different calculation, and the same tool handles it: set the replacement fee to a total-market fund’s and the case changes.

Can you harvest a loss from QQQ into QQQM?

This is the one place I would be careful, and most comparisons skip it.

The wash-sale rule disallows a loss if you buy a substantially identical security within 30 days either side of the sale. Neither the statute nor the regulation defines “substantially identical,” and IRS Publication 550 makes it a facts-and-circumstances question without ever mentioning mutual funds or ETFs in its wash-sale discussion.⁵ There is no ruling on funds at all.

Against that silence, QQQ and QQQM are the least comfortable pair you could pick. They track one index, hold the same securities in the same weights, and come from the same issuer. They differ in fee and, until December 2025, in legal structure. If any fund pair is substantially identical, this one has the fewest arguments in its defense. Summitward takes the same position in code: the tax-loss harvesting tool will not suggest QQQM as a replacement for QQQ, and a test enforces it. The full ladder from settled to speculative is in the tax-loss harvesting guide.

Should you own either?

I do not, and the reason has nothing to do with which wrapper is cheaper. The Nasdaq-100 selects companies by the exchange they list on. That is a listing rule rather than an investment thesis, and it produces results that are hard to defend on their own terms: it excludes financials by construction, it excluded Oracle when the company moved to the NYSE, and it admitted Palantir weeks after that company moved the other way.

You also already own every one of these companies. A total-market fund holds all of them at market weight, so adding the Nasdaq-100 on top is a decision to hold more of what you have, not to hold something new. The full argument, including what I hold instead and how to unwind a large position without a tax bill, is in Why I Avoid QQQ. If you want the exposure anyway, size it deliberately and use QQQM.

Key takeaways

• QQQM for buying and holding. Same index, 0.15% against 0.18%, and it tracked the index slightly closer over every period Invesco publishes as of August 31, 2026.
• QQQ for trading. Twelve times the volume, and the spread advantage is one basis point, which is worth nothing to someone buying monthly.
• The December 2025 conversion made older comparisons stale. QQQ is an open-end fund now, and its fee fell to 0.18% the same day.
• Do not sell an appreciated taxable position over three basis points. On one modeled $250,000 position with a 60% gain, the tax outruns the saving by centuries.
• Do not use QQQM to harvest a QQQ loss. One index, one issuer, the same holdings. Our own tool refuses to suggest it.
• A lower share price is not a discount. $10,000 buys the same slice of the same portfolio in either fund.

Frequently asked questions

Is QQQM better than QQQ for long-term investors?

On the numbers, yes, slightly. It costs 0.15% against 0.18% and tracked the Nasdaq-100 a little more closely over one, three and five years as of August 31, 2026. The difference is small enough that it should never justify a tax bill to act on.

Why is QQQM cheaper than QQQ?

Invesco launched it in October 2020 as a lower-cost version aimed at buy-and-hold investors, leaving QQQ as the trading vehicle. QQQ’s fee has since come down to 0.18% with its December 2025 conversion, so the gap is narrower than it used to be.

Should I hold QQQ and QQQM at the same time?

There is no diversification reason to. They hold the same securities in the same weights, so owning both is owning one position in two tickers. People do end up holding both after buying QQQM with new money rather than selling appreciated QQQ, which is a sensible reason to have two lines on a statement.

QQQ or QQQM in a Roth IRA?

QQQM, and switching costs nothing in a Roth or any other tax-advantaged account because there is no taxable event on the sale.

Do QQQ and QQQM pay the same dividends?

Both distribute quarterly from the same underlying holdings. Yields differ by roughly the fee difference, since expenses come out of income before it reaches you.

Is QQQ more liquid than QQQM?

Considerably, in volume terms: about 30.7 million shares a day against 2.6 million, as of September 4, 2026. The part that reaches a retail buyer, the bid-ask spread, is 0.00% against 0.01%. One basis point on a monthly purchase is not a reason to pay three more basis points a year.
