JPMorgan analyst Alex Yao last night downgraded Sogou (SOGO) to Underweight from Neutral and lowered his price target for the shares to $3.50 from $5.50. The analyst says he found no evidence to support the "widely adopted optimism" on an advertising growth recovery in the second half of 2019 for the China Internet sector. As a result, he's cautious on names with high exposure to online ads, or Baidu (BIDU), Weibo (WB), Sogou, Focus Media, Autohome (ATHM), and Bitauto (BITA). Yao downgraded both Sogou and Focus Media to Underweight and lowered his price target for Neutral-rated Baidu to $120 from $150.
