Shares of Twitter sunk 22% in early trading on Thursday after revealing quarterly results that showed slow user growth.
Although the social network's fourth-quarter report beat Wall Street forecasts, the rate at which Twitter is adding new users has left investors concerned.
After closing at a 52-week high of $73 the day after Christmas, Twitter stock has experienced a steady decline. Twitter shares opened Thursday's markets at $50.61.
For the quarter, the company reports an earnings per share of 2 cents on $243 million in revenue. Analysts had predicted a loss for the quarter.
