There's a new name atop the rankings of pot companies, as Nanaimo, B.C.-based Tilray Inc. has passed Smith Falls, Ont.-based Canopy Growth to become the most valuable cannabis company in the world. Tilray has about 76 million shares in total, but only just over 10 million of them are available for trading at any given time. That's far fewer than big pot companies on the TSX tend to have, including Canopy, which has a float 20 times that size — 214 million shares. "Hence Tilray's stock keeps rising — a one-way street, for at least the short term." Bloomberg data shows that more than a third of Tilray's shares are currently held by short-sellers.
