NEW YORK ( TheStreet) -- U.S. stock futures were pointing to a weaker open Tuesday on data showing stagnant economic growth in Germany in the second quarter. Futures for the Dow Jones Industrial Average were down by 69 points, or 115 points below fair value, at 11,334. Futures for the S&P 500 were lower by 12 points, or 16 points below fair value, at 1186, and Nasdaq futures were off by 20 points, or 26 points below fair value. Stocks surged Monday as a wave of deals news and signs of resilience in Japan's economy offset weak regional manufacturing data. The
German economy only grew 0.1% in the second quarter , which was well below expectations for an increase of 0.5% and below the prior quarter's growth of 1.3%. The news, along with the meeting of French President Nicolas Sarkozy and German Chancellor Angela Merkel in Paris, will likely bring concerns about the European sovereign debt crisis back to the forefront.
