NEW YORK, June 11 (Reuters) - A measure of future U.S. economic growth fell to a 44-week low in the latest week, indicating that the economy is about to slow, a research group said on Friday.
The Economic Cycle Research Institute, a New York-based independent forecasting group, said its Weekly Leading Index fell to 123.2 for the week ended June 4, down from 124.0 in the prior week.
That was the lowest level since the week of July 31, 2009, when it stood at 122.4.
Meanwhile, the index's annualized growth rate fell to -3.5 percent after a rise of 0.3 percent a week earlier.
