Economy growth gauge falls to 6-week low: ECRI

NEW YORK (Reuters) - A measure of future U.S. economic growth fell to a 6-week low while the annualized growth index declined to a 3-week low, 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 127.5 in the week ended January 21 from 128.9 the previous week.

That was the lowest since December 10, 2010, when it stood at 127.2.

The index's annualized growth rate fell to 3.5 percent from 4.1 percent a week earlier. That was the lowest since December 31, 2010, when it was 3.2 percent.
