Why We Call It the Count of the Market
A Note on Col. Leonard P. Ayres, 1879–1946, and the Daily Tally He Began
Leonard Ayres served as chief statistician of the Army in the First World War. He later became vice president and economist of the Cleveland Trust Company, where he wrote its monthly Business Bulletin. With his assistant, James F. Hughes, he kept a daily tally of how many stocks rose and how many fell. He called it the count of the market.
“I think this will make an interesting stock market statistic.”AYRES TO HUGHES, AS HUGHES RECALLED IT IN 1951
The average tells you how far the market moved. The count tells you how many stocks went along. This publication keeps that count every week, in the manner Ayres began it.
