Why Canopy Growth's Shares Jumped 22.4% This Week

Canadian cannabis company Canopy Growth (NASDAQ: CGC) saw its shares rise 22.4% so far this week, according to data from S&P Global Intelligence. Canopy's shares got a ride when Tilray, another cannabis company, said it had received approval to sell its medical marijuana in Poland. While the news only applies to Tilray, positive news for one Canadian marijuana company often affects the shares of others, as Tilray, Aurora Cannabis, and Canopy all saw big gains on Wednesday.
