Proper Research on MedX
I think Bob McWhirter was an early stage investor in MedX back at the .$10 range, he annonced he only held warrants ( One of his BNN interviews) which means when the stock got ahead of itself back in 2018 he must have sold his position.
The most knowledgable analyst that follows MedX is Doug Cooper at Beacon Securities. Doug always updates his coverage when MedX makes a material announcement. MedX has Institutional Investors now who trust Doug's guidance and that would explain the volume and higher prices. Note in the latest report MedX is still deeply undervalued on a comparative basis.
Here is Doug's report;
