Nasdaq Composite sector weights: Technology 55.2% leads the index

Technology is Nasdaq Composite's largest sector at 55.2% of the index; the top three sectors hold 80% between them (as of market close, Oct 2, 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.

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 market-cap weighted, a sector's share reflects investable size, not company count — Technology has 89 members but 55.2% of the weight. Sector pages: tech stocks, energy stocks; the full member list with weights is on the constituents page. Not investment advice.
