U.S. stock index futures slipped on Wednesday, indicating the S&P 500 may snap a three-day winning streak after weaker-than-expected euro zone economic data and ahead of a report on the U.S. housing market.
European shares fell for a second straight session as recession concerns increased after data showed the euro zone's service sector unexpectedly shrank and amid residual worries about Greece despite its success in getting a bailout.
The FTSEurofirst 300 <.FTEU3> index of top European shares was down 0.7 percent and the euro edged down 0.1 percent.
But even with the weak European data, market sentiment remained positive in a market that has seen the benchmark S&P index rise 8.3 percent for the year on improving U.S. data and hopes the euro zone debt crisis could be held in check.
"We still have a slowing economy in Europe. It's just a function of how long their shallow recession lasts, but we will take a shallow recession over what the alternative was going to be, if not for the Greek deal and the ECB's intervention," said Art Hogan, managing director of Lazard Capital Markets in New York.

"From the beginning of the financial crisis, to a person, everybody you spoke to said this thing turns around when housing bottoms out. If we start to get that type of data, which we are starting to get, we are going to certainly see a market that can continue its upward trend here," said Hogan.
