Sina swings to $336 million quarterly loss

BEIJING (AP) ? Sina Corp., a popular Chinese web portal operator, is reporting a $336.3 million quarterly loss but says revenues and microblog traffic are up.

Sina said Wednesday the loss for the quarter ended Sept. 30, equivalent to $5.10 per share, was due to writedowns in its investments in two businesses.

The Beijing-based company said quarterly revenue rose 20 percent from a year earlier to $130.3 million.
