Clearly you don't know what you are talking about. You have to post a link of an opinion from the Motley Fool... That being said, I'm going to help you out with simple math... Ready?
The fully diluted share count for GOPRO is 146M shares, the Short interest is at all time high around 40M shares... That's a bit more than 25% of the entire Outstanding shares balance currently being borrowed, which at some point in the very near future needs to be returned...
So, who has an interest that the share price drops?
TA da da daaaam! Any guess?
If you said SHORTS, you guessed right! If not, you could try again... But only one more time...
And FYI, I'm not sure where are you getting your sources, but GOPROS are way more advanced than the competition by years light! The software and add ons are going to revolutionize the market in a way that no other company will have a chance to compete... And it's all patented.
Right now, this is a small step in the road... Wait after holidays and mid next year, we will re visit your post.
