Dow Jones sector weights: Financials 29.7% leads the index

Financials is the Dow Jones Industrial Average's largest sector at 29.7% of the index; the top three sectors hold 62% between them (as of market close, Jul 22, 2026).

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 price-weighted, a sector's share reflects members' share prices, not company count — Financials has 5 members but 29.7% of the weight.
