Twitter tumbled at the opening bell on Wednesday a day after the microblogging site reported weaker-than-anticipated growth in users, even as it posted a surge in revenue. Twitter was down more than 12% to $37.27, hitting a new low. Twitter reported average monthly active users of 255 million, slightly below analysts' consensus estimates. "User growth serves as canary once more," Evercore analyst Ken Sena told clients in a note. "This quarter represents at least Twitter's 4th in a row of stepped user growth deceleration, suggesting to us that some users are beginning to find alternative elsewhere."

"The only way of discovering the limits of the possible is to venture a little way past them into the impossible."
