Twitter shares continued their seemingly endless slide on Tuesday, amid a wildly volatile stock market that appears to be hitting particularly hard tech companies with weak growth prospects.

While some tech stocks rose on Tuesday, such as Fitbit, others such as Etsy and Box continued a steady decline. Etsy, like Twitter, has been affected by concerns about growth of its user base while Box has a different issue—struggling to control costs. Both Etsy and Box went public last year and have sold off steadily since.
