Roku, Inc. Class A Common Stock logo ROKU Roku, Inc. Class A Common Stock Neutral
Nearly 791 big funds own ROKU, including the same heavy hitters as ARM, which shows serious confidence — but our data doesn't highlight a specific growth theme driving that interest the way it does for ARM.

The takeaway

Neutral

ARM comes with a clearer growth theme (AI computing) that big funds are explicitly betting on, while ROKU has strong fund interest too but no standout theme to anchor it — so the choice really comes down to whether you want a story with a clear tailwind behind it.

But watch out
Smart-money signals lag the market (13F filings ~45 days) and never guarantee direction — always check the latest price and news yourself.
