Sina (SINA +13.4%), which had fallen sharply since March, is surging following its Q1 beat, even though it was accompanied by soft Q2 revenue guidance and a warning it could see additional losses due to its investments in Weibo, which are expected to grow to $160M in 2012 from $110M-$120M last year. An upgrade from Barclays is helping Sina's cause. BofA (Neutral), though worried about margin pressure, is pleased with Sina's efforts to monetize Weibo.
