Cronos Group (TSX;CRON;NASDAQ:CRON) is up slightly in premarket trading after plunging nearly 30% on Thursday following a negative report from short seller Andrew Left. Analyst Jeremiah Katz of PI Financial says the sell-of is "unjustified" and investors should "buy on weakness" in part because he says Left's report is "light on meaningful content and had numerous red herrings". GMP analyst Martin Landry calls many of Left's claims "unfounded and biased".

Cronos CEO Michael Gorenstein told BNN Bloomberg,"I’m not able to comment on short seller reports at this time, but I can assure that all of our public oferings have been fully underwritten and we’ve had top legal advisors review our disclosure. We are very confident in our disclosure to the market.” Gorenstein is a lawyer by trade.

I've contacted Gorenstein to see if he'd like to come on our show again to update the company's story and refute Left's claims. Shares of Cronos had doubled in recent weeks partly on the expectation that it would team up with a big beverage maker. The stock had been up more than 600% this year before the big downturn yesterday.
