The Trend of the Market
S. & P. 500 Gains 0.9 Per Cent on the Week—Cumulative Advance-Decline Line 697 Issues Below February Peak—New Highs Exceed New Lows Eleventh Week—The Week’s Count Better than Even
By the Editor
The S. & P. 500 finished the week at 7,500.58, up 0.93 per cent, 1.0 per cent below its high for the year of 7,580.06, set May 29. Underneath the average, the count of the market has gone the other way. The cumulative advance-decline line made its peak on February 20 at 6,585. In the seventeen weeks since, it has given back 697 issues, and it now stands at 5,888.
The week’s own count was better than even: 5,724 issues advanced and 5,146 declined. An average that rises while the count falls is being carried by fewer stocks.
New Highs
New highs have outnumbered new lows in each of the last eleven weeks. This week the exchanges recorded 1,555 new highs against 634 new lows. The ten-week average of issues advancing is 55.0 per cent, the lowest reading since the end of May.

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.
