On a fundamental level, I really like Roku as a device and service. I've got like four of them in my house and the family uses them daily.
I'm not a long term trader at all and don't know what type of trader you are. That being said ,I would wait and see how it goes. Right now she's in a channel and you have that huge gap,could be dangerous if you are an intra-day scalper . I would even take caution if I was a swing trader. Unless she shows you otherwise and has another rally and runs towards previous high. Long term you could be good,but I still think there's going to be more pullback before she finds her resting trading zone. If a long term trader and you have no problems tying your $ up waiting for her to climb out of any possible pullback thinking she'll make a new high,go for it. As for me,I like to have my $ working for me at all times and not tied up due to some pullback. I like to cut my losses right away and move on. PS: I know many people who use ROKU and love it, I even bought 2 of them as gifts a couple of years ago for family members. ROKU is well known among the masses and has a excellent sentiment / name recognition among the public. Could turn out to be another Netflix after everything settles down, then she proceeds to do her slow climb upward,if the fundamentals support it. Best of luck to you.
