LONDON, July 30 (Reuters) - European stocks recovered from a sharp fall to close only slightly lower on Friday, and to notch up the first monthly gain since March, with U.S. data giving mixed signals on economic growth.
The FTSEurofirst 300 <
> index of top European shares fell 0.3 percent to close at 1,043.66 points, having been as low as 1,034.35 earlier. The index rose 5 percent in July, the first gain in four months.U.S. economic growth slowed in the second quarter as companies invested heavily in equipment from abroad and consumers spent less, raising concerns about the recovery in the rest of 2010. Gross domestic product expanded at a 2.4 percent annual rate, the Commerce Department said in its first estimate on Friday, compared with forecasts of a 2.5 percent growth rate.
Shares initially fell sharply in reaction, but then recovered, with some analysts remaining upbeat.
"The market had second thoughts on the data we had," said Mike Lenhoff, chief strategist and head of research at Brewin Dolphin Securities in London. "All the news is not in the headline. The investment spending was strong."
He also pointed to corporate news helping sentiment. "There is no reason for the markets to be downbeat. Earnings are strong, and companies are guiding full-year estimates up."
Other data was also mixed. A report showed business activity in the nation's Midwest region expanded more than expected this month on strong orders.
However, consumer sentiment dropped this month to a nine-month low, according to Thomson Reuters/University of Michigan's Surveys of Consumers. [
