Roku shares notch biggest daily percentage gain in four years
NEW YORK (Reuters) -Shares of video streaming company Roku Inc jumped 25% on Friday and were on track for their biggest daily percentage gain since May 2019 after the streaming device maker gave an upbeat quarterly revenue forecast. Roku's stock was last up 25.3% at $85.45 in afternoon trading and has more than doubled so far this year. Roku's strong guidance, beating consensus estimates on a pickup in digital ad sales, followed upbeat forecasts from Meta Platforms and results from Alphabet earlier this week, as both companies also reported improved ad sales in the recent quarter.
