LOL you've got to be joking. Name me a HOTTER sector right now! (Hint; there isnt one!). Well PHOT getting halted hurt the sector a little yesterday, that just leaves room for the LEGIT companies to climb higher.
IMO MJ plays are just getting started. There will be a TON of millionaires made off of them in the next few years as legalization continues. Well the "hype" may die down a little, the good companies actually producing revenues in the space are going to continue to rise. There is a reason so many of these plays have gone parabolic within the last year.
