Netflix has crashed recently. Today Roku dropped below its critical 50 day moving average, which might end a three-week long bouncing from 98. If we took a Fabonacci analysis of its pricing history from last December's 52 week low of 26.300 to this September's 52 week high of 176.55 as shown in the figure below, we can see that its current price of 129.06 is little bit over 38.2% trace at 120.88, where it could be bears' first target. Furthermore, there is a gap between 109.58 and 110.69, which might be bears' second goal. The third target could be around 200 day moving average, which is about 90 now.
Disclaimer: I have short positions on Roku. Your money your decision.
