Twitter, meanwhile, moved in the opposite direction on user growth results and second-quarter revenue guidance that fell short of analysts' forecasts. The social media platform said monetizable daily active users totaled 199 million during the three months ended March 31 and reported per-share earnings of 16 cents. Twitter plunged 14%.
