(Other definitions for dow that I've seen before include "The ...-Jones Index concerns the New York Stock Exchange" , "The . . . Jones Index gives prices on New York Stock Exchange" , "The . . .-Jones Index records share prices on New York Stock Exchange" , "The . . . Jones Index shows the New York Stock Exchange prices" .)

I've seen this clue in The Washington Post.
