That day occurred on August 15, 2018, when leading beverage alcohol company Constellation Brands ( NYSE : STZ) announced a significant expansion of their strategic partnership with Canopy Growth by investing C$5 billion into the company. Constellation increased its ownership interest in Canopy Growth to around 38 percent by acquiring 104.5 million shares directly from the company—including the exercise of existing warrants, acquired in 2017. In turn, the news caused a vicious rally in the entire Canadian cannabis complex, which had been mired in a deep summer bear market decline.
