Roku shares soared after it added the Apple TV app to its platform

Shares of streaming platform Roku (ROKU - Get Report)  on Tuesday jumped after the company said the Apple TV (AAPL - Get Report) app is available on Roku's players beginning today.

Roku users can get the app through Roku's Channel Store and subscribe to Apple TV channels directly on Roku devices.

Users of Roku will be able to access Apple TV+, the pipeline containing Apple's original video content, when it begins operation Nov. 1.

Shares of Roku, Los Gatos, Calif., finished at $132.82, up nearly 12%. The stock has more than doubled over the past year. 

Not everyone is enamored with Roku. Skeptics point out that the company faces intense competition in the market for devices that include multiple subscriptions.

For example, Comcast (CMCSA - Get Report) said last month that its internet customers can have a free streaming box that enables other services.

After that news, Loop Capital analyst Alan Gould offered a bearish take on Roku to Reuters.

"We are having a tough time justifying Roku's valuation, especially facing such substantial competitors as Amazon (AMZN - Get Report) , Apple and Google (GOOGL - Get Report) ," he said. "Now you can add Comcast."

Shares of Roku closed that day -- Sept. 18 -- at $129.88. Gould has a sell rating on the stock.
