Nasdaq-100 sector weights: Technology 59.9% leads the index

Technology is the Nasdaq-100's largest sector at 59.9% of the index; the top three sectors hold 83% between them (as of market close, Sep 8, 2026). Weights are each member's index weight estimated for today (the tracking fund's last SEC filing, rolled forward on price — see the full constituents list company by company) summed by GICS sector — so this is the real mix you own in an index fund, not an equal-count tally.

Everything left of the dashed line is a filed weight on that date; the final segment is today's estimate — the 2026-06-30 filing rolled forward on each member's price — the same basis as the headline above.

Quarterly N-PORT snapshots; sector attribution uses today's classifications, so members that have since left the index (or our universe) appear as the gray "untracked" band — larger in older quarters (~10% in 2019) by construction.

FAQ#

How many sectors does the Nasdaq-100 span?: 10 of the 11 GICS sectors are currently represented among the members we track — the Nasdaq-100 excludes financial companies by its methodology, and its market-cap weighting concentrates most of the weight in Technology. Every member belongs to exactly one GICS sector.
Which sector is performing best in 2026?: Technology leads year to date at +77.6% (weighted by index weight within the sector); Financials trails at -8.1%.

Notes & related#

Sector classifications are GICS (each company in exactly one sector); weights are from the tracking fund's N-PORT holdings rolled forward daily by price, summed per sector. Because weights are modified float-adjusted market-cap weighted (capped), a sector's share reflects investable size, not company count — Technology has 42 members but 59.9% of the weight. Sector pages: tech stocks, energy stocks; the full member list with weights is on the constituents page. Not investment advice.
