Pretty sure heightened US interest today is result of Sidoti Spring 2021 Investor Conference held Wed/Thurs.last week. It seems to me sp also responded favourably in sessions immediately following previous like conferences.You might want to fact check this but if it holds true then you will know how to position yourself on the next such announcement. I think there will be many more to come when the move to NASDAQ is complete. The signals I'm picking up suggest that the "transformative acquisition" is closer than we thought. In any case they will be raising funds so getting in front of new blood will be the IR priority.
