Part of it might be uncertainty of whether the DEA will reschedule. The democratic candidate wanted at least more study, while the president-elect and his puppets Giuliani/Christie are pretty anti-recreational and reefer-madness-scared and ignorant about the benefits to society vs. alcohol.
This affects PHOT because, without federal help with rescheduling and decriminalizing, many risks/challenges remain as barriers to business.
This is only one possibility. I am concerned, like others, about the behavior of the entire sector at the same exact time PHOT got hit. Maybe a few investors decided to dump, triggering a lot more selling? Sell the news also can happen with bloated valuations not supported by DD or revenue speculation.
I have no doubt money can be made in the sector, but.....it is not clear that PHOT can participate. Time will tell.
