Why Roku Shares Are Sliding Today

Roku Inc ROKU is trading significantly lower Wednesday after MoffettNathanson analyst Michael Nathanson downgraded the stock from a Neutral rating to a Sell rating and lowered its price target from $330 to $220.

"Simply put, we think our and the Street's long-term revenue and earnings estimates are just too damn high," Nathanson said.

The MoffettNathanson analyst believes Roku will need to monetize an "absurdly high portion" of ad-based video on demand impressions to get close to meeting expectations. 

Nathanson also cited rising competition and signs of slowing revenue growth as reasons for the downgrade.
