A graph of Leading Economic Indicators and Coincident Economic Indicators from the Conference Board.

A U.S. index of leading economic indicators rose for the sixth straight month in September, with eight of ten indicators increasing for the month, suggesting a recovery in the U.S. economy is developing, the privately held non-profit Conference Board said on Thursday.

The Conference Board Leading Economic Index grew 1 percent and now stands at 103.5 as all indicators except average workweek and building permits contributed positively to the index this month.

The six month change in the index continued to pick up to 5.7 percent in the period through September, up from 2.7 percent for the previous six months. The index was at 97.9 in March.

The LEI has risen for six consecutive months and the coincident economic index has increased in two of the last three months. These numbers strongly suggest that a recovery is developing. However, the intensity of that recovery will depend on how much, and how soon, demand picks up, said Ken Goldstein, an economist at the Conference Board.

Positive contributors, beginning with the largest, were:

Interest rate spread

Index of consumer expectations

Average weekly initial claims for unemployment insurance (inverted)

Stock prices

Real money supply

Index of supplier deliveries (vendor performance)

Manufacturers' new orders for nondefense capital goods

Manufacturers' new orders for consumer goods and materials

Negative Contributors

Average weekly manufacturing hours

Building permits

The index is constructed using real and estimated data and is revised as new data is published.

Other indices

The Coincident Economic Index was unchanged. It tracks non-farm payrolls, personal income less transfer payments, industrial production and sales from manufacturing and trade.
