Cannabis is a hot industry but impossible to track valuations of the peer group, so MicroCap.com will take it on. 1st and 15th of each month they will post a valuation table of 94 CDN listed Cannabis companies. Snapshots of the valuation table (including ACB)are posted here: https://microcap.com/p/cannabis
For better clarity, the original PDF files are available on the blog section of their site: https://blog.microcap.com/pdfhost/ . There are two PDF's for each time period. One sorted by Price to Book Value and another sorted by Enterprise Value (EV).
