The Trend of the Market

Averages Close at High for the Year—Cumulative Advance-Decline Line 707 Issues Below February Peak—New Highs Exceed New Lows Eighth Week—The Week’s Count Broad

The S. & P. 500 finished the week at 7,580.06, the highest weekly close of the year. 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 fourteen weeks since, it has given back 707 issues, and it now stands at 5,878.

The week’s own count was broad: 7,138 issues advanced and 3,789 declined. A good week, but the line remains well below its peak.

New
Highs

New highs have outnumbered new lows in each of the last eight weeks. This week the exchanges recorded 2,016 new highs against 464 new lows. The ten-week average of issues advancing is 57.2 per cent, the highest reading on record here.

None of this says the averages must turn. It says the advance has narrowed, and that the count has not confirmed the high.

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.
