Reported U.S. drop in Facebook users causes stock decline A drop in Facebook usage has led to a drop in the Facebook stock price. Karen Bleier/AFP/Getty Images July 17, 2012, 10:24 a.m. An analyst's report saying the number of Facebook users in the U.S. has fallen has caused the company's stock to fall early Tuesday after already experiencing a decline Monday. Rory Maher, an analyst for Capstone, said Facebook's number of users fell by 1.1% in the U.S. in the last six months, in a report he released Tuesday. But the decline in Facebook users isn't exclusive to the U.S. Maher also said the company has felt a drop in users in 14 of the 23 countries in which it has more than a 50% market penetration. In the nine countries that didn't see a decline in the social network's users, Facebook's growth saw very little change over the last three months, the analyst said. "This could be an issue for Facebook growth since we estimate that outside of Southeast Asia and some countries in Latin America, most markets are approaching 50 percent penetration," Maher said in the report, according to Bloomberg. That caused a 3.03% decline for the company's stock as of 9:43 a.m. Facebook's shares, which are now at $27.39, saw a big decline on Monday as well, falling 8.1%. Zynga also saw a big drop since its business is so closely tied to Facebook's. The social gaming company dropped 6.1%. But there was some good news from Maher's report. The analyst said Facebook saw growth in Japan and India. Maher said Facebook grew 60% in Japan and 20% in India, according to StreetInsider.com.
