Subscriber growth gives Netflix shares biggest gain since 2021

Streaming service is on track to add more than 20m customers this year, a big jump from fewer than 9m in 2022

Netflix shares rose 15% at one stage and are now up more than 35% this year.

Netflix shares gained the most since January 2021 after it posted its best quarter for subscriber growth in years. 

The company credited a strong programming slate and its crackdown on password sharing.
