Can we talk about $ROKU?

$Roku Inc (ROKU.US)$ Roku is currently hovering around $220 and has dropped $60 in the past month. With news over Google staying on the platform, the stock spiked, but nothing stuck.

Roku has seen prices of $400+, but what is stopping it from staying there?

According to Wolfram Alpha, Roku doesn't get the majority of its profits from actually selling Roku devices, but from ADs on the platform.

"Roku generates 14.3% of revenues from Player segment (Devices sold) while the rest comes from Platform Segment (Ads: 65% of profit)"

People are going to be getting these devices for Christmas, because of how low they are dropping their prices (You can get a 4k ROKU Device for $25 right now).

I'm expecting this stock to jump once the new year hits due to the influx of people opening Roku devices on Christmas.
