The major volatility in cannabis stocks, with some falling in recent weeks, may present an ideal opportunity for investors to buy on the dip. Five stocks positioned to outperform include Aurora Cannabis Inc. (ACB), Canopy Growth Corp. (CGC), HEXO Corp. (HEXO), Charlotteâs Web Holdings Inc. (CWBHF) and Tilray Inc. (TLRY), according to several analysts. While marijuana industry-related stocks have soared in 2019, with the ETFMG Alternative Harvest ETF (MJ) and the Horizons Marijuana Life Sciences Index ETF (HMMJ), up 44.4% and 53.2% respectively YTD, versus the S&P 500âs 17.4% return, many individual cannabis stocks have fallen recently due to a myriad of concerns.
