NEW YORK, Jan 21 (Reuters) - A measure of future U.S. economic growth rose to a 36-week high, and the annualized growth rate advanced to a 34-week high, a research group said on Friday.
The Economic Cycle Research Institute, a New York-based independent forecasting group, said its Weekly Leading Index rose to 128.9 in the week ended Jan 14 from 128.1 the previous week.
That was the highest level since May 7, when it stood at 132.1.
The index's annualized growth rate rose to 4.1 percent from 3.6 percent, originally reported as 3.7 percent, a week earlier. That was the highest since May 21, when it was 5.2 percent.
