The ten biggest companies in QQQ hold 47.8% of it as of Jun 2026 — up from 56.8% in Sep 2019. The top five hold 30.6%, and NVIDIA Corp. alone holds 7.6%. Weights are from QQQ's quarterly SEC filings, so they reconcile with the holdings list.
Each band is a rank slot, not a fixed company — band 1 is whoever is biggest in that filing. Hover a band to see who holds that slot today; switch between the top 1, 3, 5 and 10.

Share of Nasdaq-100 by weight in its tracking fund, as the fund filed it each quarter.
The effective number of stocks — one over the sum of squared weights — is how many equally weighted stocks would be exactly as concentrated. The Nasdaq-100 has 99 members and behaves like 32 at the Jun 2026 filing, against 20 in Sep 2019.
Quarterly: each bar is one quarter, the index's total return from one of the fund's quarterly filings to the next, rebuilt from its members' own total returns and filed weights — split into what the ten largest at the start of the quarter added and what everyone else added. Bars are labelled by the month the quarter ends; point at one for its figures.
Top 10 at the start of each quarterEveryone else·white tick = the index
Since Sep 2019 the index returned +326.1% (total return, from its members): the ten largest at each filing added +182.7% of it and everyone else +143.4%.
Share of weight vs share of revenue, profit and cash#
The ten largest members' share of QQQ's weight, dashed, against their share of its members' combined trailing-twelve-month revenue, net income, operating cash flow and free cash flow — at every filing. At the Jun 2026 filing they hold 48% of the weight and produce 47% of the revenue and 73% of the net income. Weight above the other lines means the market values each dollar they earn above the rest of the fund's.
Each company's share of QQQ's weight and of its members' combined trailing-twelve-month revenue, net income, operating cash flow (OCF) and free cash flow (FCF), at the Jun 2026 filing. Hover a figure for the dollars behind it.
The twenty largest members at the Jun 2026 filing, market cap against trailing-twelve-month net income. The line's slope is the index's own price-to-earnings ratio (31.3×): a company above it is priced richer per dollar of earnings than the index, below it cheaper. It is the members' aggregate, not the S&P 500's published P/E.

Members, ranks and weights are the fund's own filings, so these are the same ten companies the weight chart ranks (share classes combined), and a total moves with membership as well as with business — a company joining the index adds its whole trailing year to the bar. Each company's figures are the trailing twelve months it had filed for the quarter the index counts at that date, as reported to the SEC. Operating and free cash flow (operating cash flow less capex) leave financials out of both the top ten and the total: a bank's operating cash flow swings with its trading book and it reports no capex. A company with no figure is left out of both sides; members with figures hold at least 99.6% of the weight at every filing for revenue and 98.7% (of non-financial weight) for free cash flow, and a filing below 95% would be left blank.
The ten largest against the rest: margins, growth and capex#
The ten largest members combined against everyone else combined, at every filing. Each ratio is summed over the members that carry both of its inputs.

Revenue growth · trailing twelve months vs a year earlier
What the market pays for the ten largest members combined against everyone else combined: total market value over total trailing-twelve-month revenue (P/S) or net income (P/E), at every filing — and the top ten's multiple divided by the rest's. These are aggregates of each group, not the S&P 500's own P/E.
Into the top ten since Sep 2019: NVIDIA Corp., Micron Technology, Inc., Advanced Micro Devices, Inc., Tesla, Inc., Broadcom Inc.. Out of it: Meta Platforms, Inc., Cisco Systems, Inc., Comcast Corp., PepsiCo, Inc., Adobe Inc.. The largest member has changed too — Microsoft Corp. then, NVIDIA Corp. now. Arrivals and departures are matched by ticker, so a company that renamed or re-listed in between (Facebook to Meta) can show up on both lists.
The ten largest companies hold 47.8% of QQQ as of Jun 2026, and the largest alone (NVIDIA Corp.) holds 7.6%. In Sep 2019 the top ten held 56.8%, so the index has become less top-heavy over that span.
When was Nasdaq-100 most concentrated?
On the filings we hold, the top ten peaked at 60.8% in Jun 2023, against 47.8% now. Our weights run from Sep 2019 onward.
How many stocks does the Nasdaq-100 really behave like?
By its weights, about 32 equally weighted stocks as of the Jun 2026 filing, against 20 in Sep 2019. That "effective number" is one over the sum of squared weights: the count of equal-weight stocks that would be exactly as concentrated as the index is, whatever its member count.
Do the largest Nasdaq-100 companies earn as much as their weight?
As of the Jun 2026 filing, the ten largest hold 48% of the fund's weight but produce 47% of its members' combined revenue, 73% of their net income and 55% of their free cash flow (financials excluded from the cash figures). Where the weight runs ahead of the earnings share, the market is paying more for each dollar those companies earn than for the rest of the fund's.
Does concentration make the index riskier?
It makes it less diversified than the member count suggests: when ten names are a third of the fund, its return is largely their return, and a sector shock that hits them hits everything. It is not a market-timing signal — concentration has risen for long stretches while the index compounded — but it does mean a cap-weighted position is a much more concentrated bet than "500 companies" sounds.
Weights are as filed by the tracking fund on Form N-PORT each quarter — the index's own weights, not a market-cap approximation — and a company's share classes are combined into one row, so “top ten” means ten companies. Our filings begin Sep 2019. See also the sector mix — the other way an index can be less diversified than its member count suggests. Not investment advice.
