GPRO has fallen since its initial gap-up "pop" a few days ago, which is expected. The question now is, will the "pop" propel the stock further into bearish territory. Because it came on heavy volume with an "Island Gap," I think so.
As you can see, it was trading mostly at the bottom of its trading channel. It might fall a bit more as the price settles in. However, as we advance, I would not be surprised to see it trade more towards the top of its trading channel.
This is not trading advice. I'm new to this and still learning. Please don't listen to me.
