Jan 25, 2021 Marijuana ETFs have been among the best-performing sectors of 2021 and it's easy to see why. At the fundamental level, growth and demand are improving significantly, but legal victories (cannabis legislation passed in four states in the November elections) are quickly paving the way to legalize and de-stigmatize the use of cannabis-related products. Year-to-date, many of the big marijuana ETFs are up more than 25%. Over the past three months, several have gained more than 75%. Over the past couple of years, pot stocks have traded on speculation more than anything, but the Aphria-Tilray merger signaled that a narrative may finally be building making them a more viable investment option.
