Until the start of last year, the Canadian stock ticker âPOTâ was held by Potash Corp. of Saskatchewan, the worldâs largest potash producer. Now, following a lottery of some 40-odd hopefuls, the trading symbol has been gifted to tiny Vancouver-based cannabis company Weekend Unlimited Inc., whose stock rose by almost 150% in the wake of their Friday (Feb. 1) win. Weekend Unlimited was doing quite well on the ticker front already: Before winning big last week, the company traded under the almost-as-buzzy YOLO (âyou only live onceâ).
