An index made up of leading economic indicators rose for the 12th straight time September, according to data released Thursday.
The Conference Board's Leading Economic Index for the U.S. increased by 0.5 percent last month, in line with what economists polled by Refinitiv expected.
The gain takes into account building permits, the ISM index of new orders and stock prices.
"The US LEI improved further in September, suggesting the US business cycle remains on a strong growth trajectory heading into 2019," said Ataman Ozyildirim, director and global chair at The Conference Board. "However, the LEI's growth has slowed somewhat in recent months, suggesting the economy may be facing capacity constraints and increasingly tight labor markets."
Ozyildirim noted economic growth could top 3.5 percent in the second half of this year, but "unless the momentum in housing, orders and stock prices accelerates, that pace is unlikely to be sustained in 2019."
The U.S. housing market has been under pressure lately as interest rates rise to multiyear highs. The Commerce Department said Wednesday housing starts fell 5.3 percent last month, more than was expected.
