For the benchmark most readers mean by “US Tech 100,” check the Nasdaq-100 Index (NDX) on Nasdaq’s official index overview and use the page’s displayed as-of time with any quoted value. “US Tech 100” is not established by Nasdaq’s reviewed materials as a universal synonym for NDX, and a live level without a timestamp can be misleading.
What is the US Tech 100 index?
The Nasdaq-100, ticker NDX, is an index of 100 of the largest domestic and international non-financial companies listed on The Nasdaq Stock Market. Nasdaq describes its industry groups as including computer hardware and software, telecommunications, retail and wholesale trade, and biotechnology. Technology is prominent, but the index is not a pure technology index, and its constituents are not all US-headquartered companies.
“US Tech 100” may be a label used by a broker or other platform. Nasdaq’s official sources do not establish that every provider uses the phrase to mean exactly NDX, so check the product or index definition where you encounter it.
How to check the latest Nasdaq-100 performance
- Open Nasdaq’s NDX index overview.
- Read the value together with the page’s displayed as-of time. The index page is dynamic, and a quote copied without its timestamp may no longer describe the latest displayed level.
- For historical trends and performance tools, use Nasdaq’s Global Index Watch NDX page. Check the data and access details shown there; the available sources do not establish a particular feed speed, delay, or free-access entitlement.
No single live level is printed here because the official page’s retrieved values were inconsistent and did not establish a quote synchronized to a reliable timestamp. Use the live page itself rather than treating an undated number as current.

How the index is constructed
Nasdaq describes the Nasdaq-100 as modified market-cap weighted. In general, larger constituents can have more influence, subject to the index’s rules. The index is rebalanced quarterly and reconstituted annually in December.
Nasdaq announced methodology updates effective May 1, 2026. Its explanation says company size for eligibility now considers listed and unlisted shares, while index weighting remains based on listed shares; it also describes rank-based quarterly review processes for March, June, and September. Eligibility, caps, exceptions, and implementation are detailed and rule-dependent, so consult the current Nasdaq-100 methodology for exact requirements rather than relying on an older product guide.
How the Nasdaq-100 differs from other indexes
Before comparing performance, identify what each benchmark includes and how it is weighted. The Nasdaq-100 covers 100 large non-financial companies listed on Nasdaq; Nasdaq contrasts it with the Nasdaq Composite, which spans the Nasdaq-listed market, and the S&P 500, a broader US large-cap benchmark that includes financial companies.
| Benchmark | Eligible universe and scope | Financial companies |
|---|---|---|
| Nasdaq-100 (NDX) | 100 of the largest domestic and international non-financial companies listed on Nasdaq | Excluded by the index’s non-financial-company scope |
| Nasdaq Composite | Nasdaq-listed market; Nasdaq’s comparison describes it as spanning the Nasdaq-listed market | Included in its broader listed-market scope |
| S&P 500 | Broader US large-cap segment | Includes financial companies |
For a fair performance comparison, align the dates and return basis—for example, price return versus total return—rather than comparing figures from different periods or methodologies.

What investors can use for Nasdaq-100 exposure
An index is a calculation, not an asset an investor can buy directly. Nasdaq lists possible exposure routes including ETFs, mutual funds, annuities, futures, options, and structured products. These vehicles have different structures and risks; the list is informational, not a personal recommendation.
Nasdaq’s August 2026 explainer names Invesco QQQ Trust as an ETF that tracks the index. That is an example, not an endorsement. Fees, risks, tax treatment, product terms, and availability depend on the specific investment and jurisdiction and should be checked with current issuer materials.

Nasdaq-100 facts and scale
- The index’s inception date is January 31, 1985, according to Nasdaq.
- Nasdaq reported more than 200 tracking products and over $600 billion in global assets under management in its March 30, 2026 methodology announcement.
- Nasdaq reported $1.7 trillion of global exposure linked to the Nasdaq-100 as of June 30, 2026, in an explainer published August 19, 2026. This exposure figure is a different measure and date from the tracking-products assets figure.
Emily Spurling, Global Head of Index at Nasdaq Global Indexes, said in a May 8, 2026 interview: “The Nasdaq-100 is governed by a transparent, rules-based methodology, and any significant update follows a formal public consultation process aligned with the IOSCO Principles for Financial Benchmarks.”
