back in the day I'd say it's interesting because it had a price spike and then bottom fishers volume move it. But now days that seems to mean squat. If the action was because of a funder, it could have a 3 day pop and is worth watching closely for that.
But keep in mind, runs on the OTC the last 9 months have only lasted 3 days or so. So don't buy & hold expecting any longer term continuation. If a pop does happen, take profits quick. IMO
