Maybe Wall Street should be called "Weed Street." Big Canadian marijuana grower Canopy Growth listed its stock on the New York Stock Exchange (NYSE) earlier this year. Now it's about to have company. Aurora Cannabis (NASDAQOTH: ACBFF) begins trading on the NYSE on Tuesday, Oct. 23. Aphria (NASDAQOTH: APHQF) filed last week to list its stock on the NYSE.It's quite possible that Aurora and Aphria could see nice gains once their stocks begin trading on the world's largest stock exchange.
