The index that forecasts future economic growth rose 0.3 percent after rising 1.1 percent in December and 0.9 percent in November, the Conference Board said.
The six-month growth rate for the leading indicator is now 9.8 percent on an annualized basis, said Conference Board economist Ken Goldstein in a statement.
"This signals continued economic recovery at least through the spring," he said.
The Coincident Index measuring current business conditions rose 0.2 percent in January while the Lagging Index fell 0.1 percent, the Conference Board said.
