NEW YORK, Feb 14 (Reuters) - U.S. stocks rose modestly on Friday, with the S&P 500 on track for its first two-week winning streak of the year, as investors were once again willing to overlook some soft economic data stemming from bad weather.
U.S. export prices rose 0.2 percent in January, the third straight monthly increase in a potentially positive sign for global economic demand and the outlook for American manufacturers.
In the latest data point affected by harsh winter weather, factory production fell 0.8 percent in January, the biggest drop in more than 4-1/2 years. Investors have been willing to forgive soft data of late, attributing weak results to bad weather as opposed to a slowing economy.
"Industrial production was down. That was a big miss yet the market seems to be immune to it," said Andre Bakhos, managing director at Janlyn Capital LLC in Bernardsville, New Jersey.
"The fact the market has not been adversely affected by the weaker numbers, any of the recent numbers that have fallen short, the smart market money believes it is in fact the weather and the economy has not fallen off the tracks here."
Despite difficult weather, the preliminary reading of the Thomson Reuters/University of Michigan overall index of consumer sentiment stood at 81.2 in February, unchanged from the final January reading.
The Dow Jones industrial average rose 60.89 points or 0.38 percent, to 16,088.48, the S&P 500 gained 5.6 points or 0.31 percent, to 1,835.43 and the Nasdaq Composite added 3.226 points or 0.08 percent, to 4,243.897.
Volume is expected to be muted on Friday after the snowstorm that blanketed the U.S. East Coast on Thursday and ahead of the Presidents Day holiday on Monday, when markets will be closed.
