The Dow Jones Industrial Average (INDEXDJX:DJI) fell 64.9 points or 0.4%. The China ADR Index, compiled by Chinavestor and measuring the performance of US listed Chinese stocks, slid 4.3 points or 0.6%. Sina Corp. (NASDAQ:SINA) fell $4.0, the most among major Chinese stocks. Rumors that a new app from rival Tencent (HKG:0700) is taking away users from Sina's Weibo microblog were behind the decline.
