Yes that is how almost all these type of plays happen. Volume starts to tick up with price, sets off scanners which gets more attention.
Very rarely will news itself start the Cascade unless it is a certain type of news that gets the attention of certain players.
There is a reason a lot of the volume leaders now are dark defunct junk stops being pumped on inuendo and hype.
All that matters is, was the news positive and does it reinforce the notion this is undervalued. Yes it does, it creates an even better risk/reward profile to me. All else is just noise that will correct itself over time.
You can go jump in on a stock that is already running and maybe a P&D, which is a profitable strategy if you time it right. It is also very profitable to load a undervalued stock that will run before it starts to get attention.
