Dow Jones Transportation Averager

Dow Jones Transportation Average

A stock market index founded in 1884 by Charles Dow tracking (usually) 20 companies in the transportation industry. It is a price-weighted index, meaning that stocks with higher prices per share affect the average more. It also scales its averages to account for stock splits and other changes in the companies tracked. It includes stocks in shipping, airlines, trucking, railroads, and similar industries. It is the oldest actively used stock index in the world.
