CNBC - Feb 22 - Tinder could see new user growth cut in half by the end of June unless it gets more kindling, J.P. Morgan said. J.P. Morgan's Doug Anmuth downgraded shares to neutral from overweight. "Tinder's highly successful Gold launch in late August/early Sept 2017 accelerated subscriber growth but we believe Tinder's peak Gold surge is now behind," he wrote. Thanks to Gold offerings, Tinder's user growth skyrocketed, jumping to 476K in Q3 and 544K in Q4. But Anmuth cautioned investors that people aren't likely to continue to join Tinder at that rate; he now expects the app to add 350K users in Q1 and 230K in Q2. Anmuth did note, however, that the company expects a big Tinder product later in the year.
