Fraud Rumors Swirling About SINA?

There is some speculation that fraud rumors are responsible for a major sell-off in shares of Chinese internet company SINA Corp.

this afternoon. On the surface, these type of rumors appear somewhat ridiculous, as SINA bears little similarity to many of the Chinese reverse mergers that have in fact been found out to be frauds. Whatever the rumors are, however, they are gaining traction as SINA shares began plunging about a half hour ago and are currently down 9.35% to $113.45. Volume has been exploding on this sell off with more than 10 million SINA shares already trading hands.
