Declining Active Users Cause Twitter's Shares <br />to Plummet Twitter's stock dropped 14 percent on Friday due to a decline in monthly active users. The social media site recorded 335 million users for 2018's second quarter against expectations of <br />338.5 million. Twitter recently purged tens of millions of fake accounts, but those changes occurred after the close of the second quarter. Full year projections for Twitter also declined compared to last <br />quarter's estimates, with stock-based compensation expenses ranging from $300 million to $350 million. This is opposed to $350 million to $450 million projected <br />last quarter. News wasn't all bad as Twitter reported revenue in the second quarter of $711 million against a prediction of $696.2 million.
